Only a limited +number of features was tested using this port on Arduino hardware, so be careful when using any of the untested features. + +The library has only been tested with LoRaWAN 1.0.2 networks and does not have the separated key structure defined by LoRaWAN 1.1. + +What certainly works: + + - Sending packets uplink, taking into account duty cycling. + - Encryption and message integrity checking. + - Receiving downlink packets in the RX2 window. + - Custom frequencies and datarate settings. + - Over-the-air activation (OTAA / joining). + - Receiving downlink packets in the RX1 and RX2 windows. + - Some MAC command processing. + +What has not been tested: + + - Receiving and processing all MAC commands. + - Class B operation. + - FSK has not been extensively tested. + +If you try one of these untested features and it works, be sure to let +us know (creating a github issue is probably the best way for that). + +## Configuration + +A number of features can be enabled or disabled at compile time. +This is done by adding the desired settings to the file +`project_settings/lmic_project_config.h`. The `project_settings` +directory is the only directory that contains files that you +should edit to match your project; we organize things this way +so that your local changes are more clearly separated from +the distribution files. The Arduino environment doesn't give +us a better way to do this. + +Unlike other ports of the LMIC code, in this port, you should not edit `src/lmic/config.h` to configure this package. + +The following configuration variables are available. + +### Selecting the LoRaWAN Region Configuration + +The library supports the following regions: + +`-D` variable | CFG region name | CFG region value | LoRa Spec Reference| Frequency +------------|-----------------|:----------------:|:-------------------:|-------- +`-D CFG_eu868` | `LMIC_REGION_eu868` | 1 | 2.1 | EU 863-870 MHz ISM +`-D CFG_us915` | `LMIC_REGION_us915` | 2 | 2.2 | US 902-928 MHz ISM +`-D CFG_au921` | `LMIC_REGION_au921` | 5 | 2.5 | Australia 915-928 MHz ISM +`-D CFG_as923` | `LMIC_REGION_as923` | 7 | 2.7 | Asia 923 MHz ISM +`-D CFG_in866` | `LMIC_REGION_in866` | 9 | 2.9 | India 865-867 MHz ISM + +You should define exactly one of `CFG_...` variables. If you don't, +the library assumes `CFG_eu868`. The library changes configuration pretty substantially +according to the region. Some of the differences are listed below. + +#### eu868, as923, in866 + +If the library is configured for EU868, AS923, or IN866 operation, we make +the following changes: +- Add the API `LMIC_setupBand()`. +- Add the constants `MAX_CHANNELS`, `MAX_BANDS`, `LIMIT_CHANNELS`, `BAND_MILLI`, +`BAND_CENTI`, `BAND_DECI`, and `BAND_AUX`. + +#### us915, au921 + +If the library is configured for US915 operation, we make the following changes: +- Add the APIs `LMIC_enableChannel()`, +`LMIC_enableSubBand()`, `LMIC_disableSubBand()`, and `LMIC_selectSubBand()`. +- Add the constants `MAX_XCHANNELS`. +- Add a number of additional `DR_...` symbols. + +### Selecting the target radio transceiver + +You should define one of the following variables. If you don't, the library assumes +sx1276. There is a runtime check to make sure the actual transceiver matches the library +configuration. + +`#define CFG_sx1272_radio 1` + +Configures the library for use with an sx1272 transceiver. + +`#define CFG_sx1276_radio 1` + +Configures the library for use with an sx1276 transceiver. + +### Controlling use of interrupts + +`#define LMIC_USE_INTERRUPTS` + +If defined, configures the library to use interrupts for detecting events from the transceiver. If left undefined, the library will poll for events from the transceiver. See [Timing](#timing) for more info. + +### Disabling PING + +`#define DISABLE_PING` + +If defined, removes all code needed for PING. Removes the APIs `LMIC_setPingable()` and `LMIC_stopPingable()`. +Class A devices don't support PING, so defining `DISABLE_PING` is often a good idea. + +By default, PING support is included in the library. + +### Disabling Beacons + +`#define DISABLE_BEACONS` + +If defined, removes all code needed for handling beacons. Removes the APIs `LMIC_enableTracking()` and `LMIC_disableTracking()`. +Class A devices don't support beacons, so defining `DISABLE_BEACONS` might be a good idea. + + +### Rarely changed variables ### + +The remaining variables are rarely used, but we list them here for completeness. + +#### Changing debug output + +`#define LMIC_PRINTF_TO SerialLikeObject` + +This variable should be set to the name of a `Serial`-like object, used for printing messages. If not defined, `Serial` +is assumed. + +#### Getting debug from the RF library + +`#define LMIC_DEBUG_LEVEL number /* 0, 1, or 2 */` + +This variable determines the amount of debug output to be produced by the library. The default is `0`. + +If `LMIC_DEBUG_LEVEL` is zero, no output is produced. If `1`, limited output is produced. If `2`, more extensive +output is produced. If non-zero, printf() is used, and the Arduino environment must be configured to support it, +otherwise the sketch will crash at runtime. + +#### Selecting the AES library + +The library comes with two AES implementations. The original implementation is better on +ARM processors becasue it's faster, but it's larger. For smaller AVR8 processors, a +second library ("IDEETRON") is provided that has a smaller code footprint. +You may define one of the following variables to choose the AES implementation. If you don't, +the library uses the IDEETRON version. + +`#define USE_ORIGINAL_AES` + +If defined, the original AES implementation is used. + +`#define USE_IDEETRON_AES` + +If defined, the IDEETRON AES implementation is used. + +#### Defining the OS Tick Frequency + +`#define US_PER_OSTICK_EXPONENT number` + +This variable should be set to the base-2 logarithm of the number of microseconds per OS tick. The default is 4, +which indicates that each tick corresponds to 16 microseconds (because 16 == 2^4). + +#### Setting the SPI-bus frequency + +`#define LMIC_SPI_FREQ floatNumber` + +This variable sets the default frequency for the SPI bus connection to the transceiver. The default is `1E6`, meaning 1 MHz. However, this can be overridden by the contents of the `lmic_pinmap` structure, and we recommend that you use that approach rather than editing the `project_settings/lmic_project_config.h` file. + +#### Changing handling of runtime assertion failures + +The variables `LMIC_FAILURE_TO` and `DISABLE_LMIC_FAILURE_TO` +control the handling of runtime assertion failures. By default, assertion messages are displayed using +the `Serial` object. You can define LMIC_FAILURE_TO to be the name of some other `Print`-like obect. You can +also define `DISABLE_LMIC_FAILURE_TO` to any value, in which case assert failures will silently halt execution. + +#### Disabling JOIN + +`#define DISABLE_JOIN` + +If defined, removes code needed for OTAA activation. Removes the APIs `LMIC_startJoining()` and `LMIC_tryRejoin()`. + +#### Disabling Class A MAC commands + +`DISABLE_MCMD_DCAP_REQ`, `DISABLE_MCMD_DN2P_SET`, and `DISABLE_MCMD_SNCH_REQ` respectively disable code for various Class A MAC +commands. + +#### Disabling Class B MAC commands + +`DISABLE_MCMD_PING_SET` disables the PING_SET MAC commands. It's implied by `DISABLE_PING`. + +`DISABLE_MCMD_BCNI_ANS` disables the next-beacon start command. It's implied by `DISABLE_BEACON` + +#### Special purpose + +`#define DISABLE_INVERT_IQ_ON_RX` disables the inverted Q-I polarity on RX. If this is defined, end-devices will be able +to receive messages from each other, but will not be able to hear the gateway. + +## Supported hardware + +This library is intended to be used with plain LoRa transceivers, +connecting to them using SPI. In particular, the SX1272 and SX1276 +families are supported (which should include SX1273, SX1277, SX1278 and +SX1279 which only differ in the available frequencies, bandwidths and +spreading factors). It has been tested with both SX1272 and SX1276 +chips, using the Semtech SX1272 evaluation board and the HopeRF RFM92 +and RFM95 boards (which supposedly contain an SX1272 and SX1276 chip +respectively). + +This library contains a full LoRaWAN stack and is intended to drive +these Transceivers directly. It is *not* intended to be used with +full-stack devices like the Microchip RN2483 and the Embit LR1272E. +These contain a transceiver and microcontroller that implements the +LoRaWAN stack and exposes a high-level serial interface instead of the +low-level SPI transceiver interface. + +This library is intended to be used inside the Arduino environment. It +should be architecture-independent, so it should run on "normal" AVR +arduinos, but also on the ARM-based ones, and some success has been seen +running on the ESP8266 board as well. It was tested on the Arduino Uno, +Pinoccio Scout, Teensy LC and 3.x, ESP8266, Arduino 101, Adafruit Feather M0 LoRa 900. It has been tested on the Lattice RISC-V CPU soft core running in an iCE40 UltraPlus, and also on the Murata LoRaWAN module on the MCCI Catena 4551. + +This library an be quite heavy on small systems, especially if the fairly small ATmega +328p (such as in the Arduino Uno) is used. In the default configuration, +the available 32K flash space is nearly filled up (this includes some +debug output overhead, though). By disabling some features in `project_settings/lmic_project_config.h` +(like beacon tracking and ping slots, which are not needed for Class A devices), +some space can be freed up. + +## Connections + +To make this library work, your Arduino (or whatever Arduino-compatible +board you are using) should be connected to the transceiver. In some cases (such as the Adafruit Feather series and Murata-based boards such as the MCCI Catena 4551), the settings are fixed by the board, and you won't have to worry about many of these details. However, you'll need to find the configuration that's suitable for your board. + +> To help you know if you have to worry, we'll call such boards "pre-integrated" and prefix each section with suitable guidance. + +The exact +connections are a bit dependent on the transceiver board and Arduino +used, so this section tries to explain what each connection is for and +in what cases it is (not) required. + +Note that the SX1272 module runs at 3.3V and likely does not like 5V on +its pins (though the datasheet is not say anything about this, and my +transceiver did not obviously break after accidentally using 5V I/O for +a few hours). To be safe, make sure to use a level shifter, or an +Arduino running at 3.3V. The Semtech evaluation board has 100 ohm resistors in +series with all data lines that might prevent damage, but I would not +count on that. + +### Power + +> If you're using a pre-integrated board, you can skip this section. + +The SX127x transceivers need a supply voltage between 1.8V and 3.9V. +Using a 3.3V supply is typical. Some modules have a single power pin +(like the HopeRF modules, labeled 3.3V) but others expose multiple power +pins for different parts (like the Semtech evaluation board that has +`VDD_RF`, `VDD_ANA` and `VDD_FEM`), which can all be connected together. +Any *GND* pins need to be connected to the Arduino *GND* pin(s). + +### SPI + +> If you're using a pre-integrated board, you can skip this section, and instead refer to your board's documentation on the pins to be used. + +The primary way of communicating with the transceiver is through SPI +(Serial Peripheral Interface). This uses four pins: MOSI, MISO, SCK and +SS. The former three need to be directly connected: so MOSI to MOSI, +MISO to MISO, SCK to SCK. Where these pins are located on your Arduino +varies, see for example the "Connections" section of the [Arduino SPI +documentation](SPI). + +The SS (slave select) connection is a bit more flexible. On the SPI +slave side (the transceiver), this must be connect to the pin +(typically) labeled *NSS*. On the SPI master (Arduino) side, this pin +can connect to any I/O pin. Most Arduinos also have a pin labeled "SS", +but this is only relevant when the Arduino works as an SPI slave, which +is not the case here. Whatever pin you pick, you need to tell the +library what pin you used through the pin mapping (see [below](#pin-mapping)). + +[SPI]: https://www.arduino.cc/en/Reference/SPI + +### DIO pins + +> If you're using a pre-integrated board, you can ignore this section; refer to your board's documentation for information on what DIO pins need to be used. + +The DIO (digital I/O) pins on the SX127x can be configured +for various functions. The LMIC library uses them to get instant status +information from the transceiver. For example, when a LoRa transmission +starts, the DIO0 pin is configured as a TxDone output. When the +transmission is complete, the DIO0 pin is made high by the transceiver, +which can be detected by the LMIC library. + +The LMIC library needs only access to DIO0, DIO1 and DIO2, the other +DIOx pins can be left disconnected. On the Arduino side, they can +connect to any I/O pin. If interrupts are used, the accuracy of timing +will be improved, particularly the rest of your `loop()` function has +lengthy calculations; but in that case, the enabled DIO pins must all +support rising-edge interrupts. See the [Timing](#timing) section below. + +In LoRa mode the DIO pins are used as follows: + * DIO0: TxDone and RxDone + * DIO1: RxTimeout + +In FSK mode they are used as follows:: + * DIO0: PayloadReady and PacketSent + * DIO2: TimeOut + +Both modes need only 2 pins, but the transceiver does not allow mapping +them in such a way that all needed interrupts map to the same 2 pins. +So, if both LoRa and FSK modes are used, all three pins must be +connected. + +The pins used on the Arduino side should be configured in the pin +mapping in your sketch, by setting the values of `lmic_pinmap::dio[0]`, `[1]`, and `[2]` (see [below](#pin-mapping)). + +### Reset + +> If you're using a pre-configured module, refer to the documentation for your board. + +The transceiver has a reset pin that can be used to explicitly reset +it. The LMIC library uses this to ensure the chip is in a consistent +state at startup. In practice, this pin can be left disconnected, since +the transceiver will already be in a sane state on power-on, but +connecting it might prevent problems in some cases. + +On the Arduino side, any I/O pin can be used. The pin number used must +be configured in the pin mapping `lmic_pinmap::rst` field (see [below](#pin-mapping)). + +### RXTX + +> If you're using a pre-configured module, refer to the documentation for your board. + +The transceiver contains two separate antenna connections: One for RX +and one for TX. A typical transceiver board contains an antenna switch +chip, that allows switching a single antenna between these RX and TX +connections. Such a antenna switcher can typically be told what +position it should be through an input pin, often labeled *RXTX*. + +The easiest way to control the antenna switch is to use the *RXTX* pin +on the SX127x transceiver. This pin is automatically set high during TX +and low during RX. For example, the HopeRF boards seem to have this +connection in place, so they do not expose any *RXTX* pins and the pin +can be marked as unused in the pin mapping. + +Some boards do expose the antenna switcher pin, and sometimes also the +SX127x *RXTX* pin. For example, the SX1272 evaluation board calls the +former *FEM_CTX* and the latter *RXTX*. Again, simply connecting these +together with a jumper wire is the easiest solution. + +Alternatively, or if the SX127x *RXTX* pin is not available, LMIC can be +configured to control the antenna switch. Connect the antenna switch +control pin (e.g. *FEM_CTX* on the Semtech evaluation board) to any I/O +pin on the Arduino side, and configure the pin used in the pin map (see +[below](#pin-mapping)). + +The configuration entry `lmic_pinmap::rxtx` configures the pin to be used for the *RXTX* control function, in terms of the Arduino `wire.h` digital pin number. If set to `LMIC_UNUSED_PIN`, then the library assumes that software does not need to control the antenna switch. + +### RXTX Polarity + +If an external switch is used, you also must specify the polarity. Some modules want *RXTX* to be high for transmit, low for receive; Others want it to be low for transmit, high for receive. The Murata module, for example, requires that *RXTX* be *high* for receive, *low* for transmit. + +The configuration entry `lmic_pinmap::rxtx_rx_active` should be set to the state to be written to the *RXTX* pin to make the receiver active. The opposite state is written to make the transmitter active. If `lmic_pinmap::rxtx` is `LMIC_UNUSED_PIN`, then the value of `lmic_pinmap::rxtx_rx_active` is ignored. + +### Pin mapping + +> For pre-configured boards, refer to the documentation on your board for the required settings.

As described above, a variety of configurations are possible. To tell the LMIC library how your board is configured, you must declare a variable containing a pin mapping struct in the sketch file. + +For example, this could look like this: + +```c++ + lmic_pinmap lmic_pins = { + .nss = 6, + .rxtx = LMIC_UNUSED_PIN, + .rst = 5, + .dio = {2, 3, 4}, + // optional: set polarity of rxtx pin. + .rxtx_rx_active = 0, + // optional: set RSSI cal for listen-before-talk + // this value is in dB, and is added to RSSI + // measured prior to decision. + // Must include noise guardband! Ignored in US, + // EU, IN, other markets where LBT is not required. + .rssi_cal = 0, + // optional: override LMIC_SPI_FREQ if non-zero + .spi_freq = 0, + }; +``` + +The names refer to the pins on the transceiver side, the numbers refer +to the Arduino pin numbers (to use the analog pins, use constants like +`A0`). For the DIO pins, the three numbers refer to DIO0, DIO1 and DIO2 +respectively. Any pins that are not needed should be specified as +`LMIC_UNUSED_PIN`. The nss and dio0 pin is required, the others can +potentially left out (depending on the environments and requirements, +see the notes above for when a pin can or cannot be left out). + +The name of the variable containing this struct must always be `lmic_pins`, which is a special name recognized by the library. + + +#### Adafruit Feather M0 LoRa + +See Adafruit's [Feather M0 LoRa product page](https://www.adafruit.com/product/3178). +This board uses the following pin mapping, as shown in the various "...-feather" +sketches. + +DIO0 is hard-wired by Adafruit to Arduino D3, but DIO1 is not connected to any Arduino pin (it comes to JP1 pin 1, but is not otherwise connected).

Remember that you may also have to change `config.h` + from defaults.

In particular, the library must note +when a packet finishes transmitting, so it can open up the RX1 and RX2 +receive windows at a fixed time after the end of transmission. The library does this +by watching for rising edges on the DIO0 output of the SX127x, and noting the time. + +The library observes and processes rising edges on the pins as part of `os_runloop()` processing. +This can be configured in one of two ways (see +[Controlling use of interrupts](#controlling-use-of-interrupts)). + +By default, the routine `hal_io_check()` +polls the enabled pins to determine whether an event has occured. This approach +allows use of any CPU pin to sense the DIOs, and makes no assummptions about +interrupts. However, it means that the end-of-transmit event is not observed +(and time-stamped) until `os_runloop()` is called. + +Optionally, you can configure the LMIC library to use interrupts. The +interrupt handlers capture the time of +the event. Actual processing is done the next time that `os_runloop()` +is called, using the captured time. However, this requires that the +DIO pins be wired to Arduino pins that support rising-edge interrupts. + +Fortunately, LoRa is a fairly slow protocol and the timing of the +receive windows is not super critical. To synchronize transmitter and +receiver, a preamble is first transmitted. Using LoRaWAN, this preamble +consists of 8 symbols, of which the receiver needs to see 4 symbols to +lock on. The current implementation tries to enable the receiver for 5 +symbol times at 1.5 symbol after the start of the receive window, +meaning that a inaccuracy of plus or minus 2.5 symbol times should be +acceptable. + +The HAL bases all timing on the Arduino `micros()` timer, which has a platform-specific +granularity, and is based on the primary microcontroller clock. + +At the fastest LoRa setting supported by the SX127x (SF5BW500) a +single preamble symbol takes 64 microseconds, so the receive window timing should +be accurate within 160 microseconds (for LoRaWAN this is SF7BW250, needing accuracy +within 1280μs). This accuracy should also be +feasible with the polling approach used, provided that the LMIC loop is +run often enough. + +If using an internal oscillator (which is 1% - 10% +accurate, depending on calibration), or if your other `loop()` processing +is time consuming, you may have to use [`LMIC_setClockError()`](#lmic_setclockerror) +to cause the library to leave the radio on longer. + +An even more accurate solution could be to use a dedicated timer with an +input capture unit, that can store the timestamp of a change on the DIO0 +pin (the only one that is timing-critical) entirely in hardware. +Experience shows that this is not normally required, so we leave this as +a customization to be performed on a platform-by-platfom basis. We provide +a special API, `radio_irq_handler_v2(u1_t dio, ostime_t tEvent)`. This +API allows you to supply a hardware-captured time for extra accuracy. + +The practical consequence of inaccurate timing is reduced battery life; +the LMIC must turn on the reciever earlier in order to be sure to capture downlink packets. + +### `LMIC_setClockError()` + +You may call this routine during intialization to infom the LMIC code about the timing accuracy of your system. + +```c++ +enum { MAX_CLOCK_ERROR = 65535 }; + +void LMIC_setClockError( + u2_t error +); +``` + +This function sets the anticipated relative clock error. `MAX_CLOCK_ERROR` +represents +/- 100%, and 0 represents no additional clock compensation. +To allow for an error of 20%, you would call + +```c++ +LMIC_setClockError(MAX_CLOCK_ERROR * 20 / 100); +``` + +Setting a high clock error causes the RX windows to be opened earlier than it otherwise would be. This causes more power to be consumed. For Class A devices, this extra power is not substantial, but for Class B devices, this can be significant. + +This clock error is not reset by `LMIC_reset()`. + +## Downlink datarate + +Note that the datarate used for downlink packets in the RX2 window varies by region. Consult your network's manual for any divergences from the LoRaWAN Regional Parameters. This library assumes that the network follows the regional default. + +Some networks use different values than the specification. For example, in Europe, the specification default is DR0 (SF12, 125 kHz bandwidth). However, iot.semtech.com and The Things Network both used SF9 / 125 kHz or DR3). If using over-the-air activation (OTAA), the network will download RX2 parameters as part of the JoinAccept message; the LMIC will honor the downloaded parameters. + +However, when using personalized activate (ABP), it is your +responsibility to set the right settings, e.g. by adding this to your +sketch (after calling `LMIC_setSession`). `ttn-abp.ino` already does +this. + +```c++ +LMIC.dn2Dr = DR_SF9; +``` + +## Encoding Utilities + +It is generally important to make LoRaWAN messages as small as practical. Extra bytes mean extra transmit time, which wastes battery power and interferes with other nodes on the network. + +To simplify coding, the Arduino header file defines some data encoding utility functions to encode floating-point data into `uint16_t` values using `sflt16` or `uflt16` bit layout. For even more efficiency, there are versions that use only the bottom 12 bits of the `uint16_t`, allowing for other bits to be carried in the top 4 bits, or for two values to be crammed into three bytes. + +- `uint16_t LMIC_f2sflt16(float)` converts a floating point number to a [`sflt16`](#sflt16)-encoded `uint16_t`. +- `uint16_t LMIC_f2uflt16(float)` converts a floating-point number to a [`uflt16`](#uflt16)-encoded `uint16_t`. +- `uint16_t LMIC_f2sflt12(float)` converts a floating-point number to a [`sflt12`](#sflt12)-encoded `uint16_t`, leaving the top four bits of the result set to zero. +- `uint16_t LMIC_f2uflt12(float)` converts a floating-point number to a [`uflt12`](#sflt12)-encoded `uint16_t`, leaving the top four bits of the result set to zero. + +JavaScript code for decoding the data can be found in the following sections. + +### sflt16 + +A `sflt16` datum represents an unsigned floating point number in the range [0, 1.0), transmitted as a 16-bit field.

The full 16-bit number is 0x1AB. +2. `b` is therefore 0x1, and `b`-15 is -14. 2^-14 is 1/16384 +3. `f` is 0xAB. 0xAB/256 is 0.67 +4. `f * 2^(b-15)` is therefore 0.67/16384 or 0.0000408 (to three significant digits) + +Floating point mavens will immediately recognize: + +* There is no sign bit; all numbers are positive. +* Numbers do not need to be normalized (although in practice they always are). +* The format is somewhat wasteful, because it explicitly transmits the most-significant bit of the fraction. (Most binary floating-point formats assume that `f` is is normalized, which means by definition that the exponent `b` is adjusted and `f` is shifted left until the most-significant bit of `f` is one. Most formats then choose to delete the most-significant bit from the encoding. If we were to do that, we would insist that the actual value of `f` be in the range 256 .. 512, and then transmit only `f - 256`, saving a bit. However, this complicates the handling of gradual underflow; see next point.) +* Gradual underflow at the bottom of the range is automatic and simple with this encoding; the more sophisticated schemes need extra logic (and extra testing) in order to provide the same feature. + +#### JavaScript decoder + +```javascript +function uflt122f(rawUflt12) + { + // rawUflt12 is the 2-byte number decoded from wherever; + // it's in range 0..0xFFF (12 bits). For safety, we mask + // on entry and discard the high-order bits. + // bits 11..8 are the exponent + // bits 7..0 are the the mantissa. Unlike IEEE format, + // the msb is explicit; this means that numbers + // might not be normalized, but makes coding for + // underflow easier. + // As with IEEE format, negative zero is possible, so + // we special-case that in hopes that JavaScript will + // also cooperate. + // + // The result is a number in the half-open interval [0, 1.0); + // + + // throw away high bits for repeatability. + rawUflt12 &= 0xFFF; + + // extract the exponent + var exp1 = (rawUflt12 >> 8) & 0xF; + + // extract the "mantissa" (the fractional part) + var mant1 = (rawUflt12 & 0xFF) / 256.0; + + // convert back to a floating point number. We hope + // that Math.pow(2, k) is handled efficiently by + // the JS interpreter! If this is time critical code, + // you can replace by a suitable shift and divide. + var f_unscaled = sSign * mant1 * Math.pow(2, exp1 - 15); + + return f_unscaled; + } +``` + +## Release History + +- V2.2.2 adds `ttn-abp-feather-us915-dht22.ino` example, and fixes some documentation typos. It also fixes encoding of the `Margin` field of the `DevStatusAns` MAC message ([#130](https://github.com/mcci-catena/arduino-lmic/issues/130)). This makes Arduino LMIC work with newtorks implemented with [LoraServer](https://www.loraserver.io/). + +- V2.2.1 corrects the value of `ARDUINO_LMIC_VERSION` ([#123](https://github.com/mcci-catena/arduino-lmic/issues/123)), allows ttn-otaa-feather-us915 example to compile for the Feather 32u4 LoRa ([#116](https://github.com/mcci-catena/arduino-lmic/issues/116)), and addresses documentation issues ([#122](https://github.com/mcci-catena/arduino-lmic/issues/122), [#120](https://github.com/mcci-catena/arduino-lmic/issues/120)). + +- V2.2.0 adds encoding functions and `tn-otaa-feather-us915-dht22.ino` example. Plus a large number of issues: [#59](https://github.com/mcci-catena/arduino-lmic/issues/59), [#60](https://github.com/mcci-catena/arduino-lmic/issues/60), [#63](https://github.com/mcci-catena/arduino-lmic/issues/63), [#64](https://github.com/mcci-catena/arduino-lmic/issues/47) (listen-before-talk for Japan), [#65](https://github.com/mcci-catena/arduino-lmic/issues/65), [#68](https://github.com/mcci-catena/arduino-lmic/issues/68), [#75](https://github.com/mcci-catena/arduino-lmic/issues/75), [#78](https://github.com/mcci-catena/arduino-lmic/issues/78), [#80](https://github.com/mcci-catena/arduino-lmic/issues/80), [#91](https://github.com/mcci-catena/arduino-lmic/issues/91), [#98](https://github.com/mcci-catena/arduino-lmic/issues/98), [#101](https://github.com/mcci-catena/arduino-lmic/issues/101). Added full Travis CI testing, switched to travis-ci.com as the CI service. Prepared to publish library in the offical Arduino library list. + +- V2.1.5 fixes issue [#56](https://github.com/mcci-catena/arduino-lmic/issues/56) (a documentation bug). Documentation was quickly reviewed and other issues were corrected. The OTAA examples were also updated slightly. + +- V2.1.4 fixes issues [#47](https://github.com/mcci-catena/arduino-lmic/issues/47) and [#50](https://github.com/mcci-catena/arduino-lmic/issues/50) in the radio driver for the SX1276 (both related to handling of output power control bits). + +- V2.1.3 has a fix for issue [#43](https://github.com/mcci-catena/arduino-lmic/issues/43): handling of `LinkAdrRequest` was incorrect for US915 and AU921; when TTN added ADR support on US and AU, the deficiency was revealed (and caused an ASSERT). + +- V2.1.2 has a fix for issue [#39](https://github.com/mcci-catena/arduino-lmic/issues/39) (adding a prototype for `LMIC_DEBUG_PRINTF` if needed). Fully upward compatible, so just a patch. + +- V2.1.1 has the same content as V2.1.2, but was accidentally released without updating `library.properties`. + +- V2.1.0 adds support for the Murata LoRaWAN module. + +- V2.0.2 adds support for the extended bandplans. + +## Contributions + +This library started from the IBM V1.5 open-source code. + +- Thomas Telkamp and Matthijs Kooijman ported V1.5 to Arduino and did a lot of bug fixing. + +- Terry Moore, LeRoy Leslie, Frank Rose, and ChaeHee Won did a lot of work on US support. + +- Terry Moore added the AU921, AS923 and IN866 bandplans, and created the regionalization framework. + +- [@tanupoo](https://github.com/tanupoo) of the WIDE Project debugged AS923JP and LBT support. + +## Trademark Acknowledgements + +LoRa is a registered trademark of the LoRa Alliance.
