-Arduino-LMIC library
-====================
-This repository contains the IBM LMIC (LoraMAC-in-C) library, slightly
-modified to run in the Arduino environment, allowing using the SX1272,
-SX1276 tranceivers and compatible modules (such as some HopeRF RFM9x
-modules).
-
-This library mostly exposes the functions defined by LMIC, it makes no
-attempt to wrap them in a higher level API that is more in the Arduino
-style. To find out how to use the library itself, see the examples, or
-see the PDF file in the doc subdirectory.
-
-This library requires Arduino IDE version 1.6.6 or above, since it
-requires C99 mode to be enabled by default.
-
-Installing
-----------
-To install this library:
-
- - install it using the Arduino Library manager ("Sketch" -> "Include
-   Library" -> "Manage Libraries..."), or
- - download a zipfile from github using the "Download ZIP" button and
-   install it using the IDE ("Sketch" -> "Include Library" -> "Add .ZIP
-   Library..."
- - clone this git repository into your sketchbook/libraries folder.
-
-For more info, see https://www.arduino.cc/en/Guide/Libraries
-
-Features
---------
-The LMIC library provides a fairly complete LoRaWAN Class A and Class B
-implementation, supporting the EU-868 and US-915 bands. Only a limited
-number of features was tested using this port on Arduino hardware, so be
-careful when using any of the untested features.
-
-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).
-
-What has not been tested:
- - Receiving downlink packets in the RX1 window.
- - Receiving and processing MAC commands.
- - Class B operation.
-
-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 configured or disabled by editing the
-`config.h` file in the library folder. Unfortunately the Arduino
-environment does not offer any way to do this (compile-time)
-configuration from the sketch, so be careful to recheck your
-configuration when you switch between sketches or update the library.
-
-At the very least, you should set the right type of transceiver (SX1272
-vs SX1276) in config.h, most other values should be fine at their
-defaults.
-
-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.
-
-This library an be quite heavy, 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 `config.h`
-(like beacon tracking and ping slots, which are not typically needed),
-some space can be freed up. Some work is underway to replace the AES
-encryption implementation, which should free up another 8K or so of
-flash in the future, making this library feasible to run on a 328p
-microcontroller.
-
-Connections
------------
-To make this library work, your Arduino (or whatever Arduino-compatible
-board you are using) should be connected to the transceiver. 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
-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
-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).
-
-[SPI]: https://www.arduino.cc/en/Reference/SPI
-
-### DIO pins
-The DIO (digitial I/O) pins on the transceiver board 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, since the current implementation does not use
-interrupts or other special hardware features (though this might be
-added in the feature, see also the "Timing" section).
-
-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 tranceiver 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 (see below).
-
-### Reset
-The transceiver has a reset pin that can be used to explicitely 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 (see below).
-
-### RXTX
-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). It is not entirely clear why would *not* want the transceiver to
-control the antenna directly, though.
-
-### Pin mapping
-As described above, most connections can use arbitrary I/O pins on the
-Arduino side. To tell the LMIC library about these, a pin mapping struct
-is used in the sketch file.
-
-For example, this could look like this:
-
-	lmic_pinmap lmic_pins = {
-	    .nss = 6,
-	    .rxtx = LMIC_UNUSED_PIN,
-	    .rst = 5,
-	    .dio = {2, 3, 4},
-	};
-
-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 this struct must always be `lmic_pins`, which is a special name
-recognized by the library.
-
-#### LoRa Nexus by Ideetron
-This board uses the following pin mapping:
-
-    const lmic_pinmap lmic_pins = {
-        .nss = 10,
-        .rxtx = LMIC_UNUSED_PIN,
-        .rst = LMIC_UNUSED_PIN, // hardwired to AtMega RESET
-        .dio = {4, 5, 7},
-    };
-
-Examples
---------
-This library currently provides three examples:
-
- - `ttn-abp.ino` shows a basic transmission of a "Hello, world!" message
-   using the LoRaWAN protocol. It contains some frequency settings and
-   encryption keys intended for use with The Things Network, but these
-   also correspond to the default settings of most gateways, so it
-   should work with other networks and gateways as well. This example
-   uses activation-by-personalization (ABP, preconfiguring a device
-   address and encryption keys), and does not employ over-the-air
-   activation.
-
-   Reception of packets (in response to transmission, using the RX1 and
-   RX2 receive windows is also supported).
-
- - `ttn-otaa.ino` also sends a "Hello, world!" message, but uses over
-   the air activation (OTAA) to first join a network to establish a
-   session and security keys. This was tested with The Things Network,
-   but should also work (perhaps with some changes) for other networks.
-
- - `raw.ino` shows how to access the radio on a somewhat low level,
-   and allows to send raw (non-LoRaWAN) packets between nodes directly.
-   This is useful to verify basic connectivity, and when no gateway is
-   available, but this example also bypasses duty cycle checks, so be
-   careful when changing the settings.
-
-Timing
-------
-Unfortunately, the SX127x tranceivers do not support accurate
-timekeeping themselves (there is a sequencer that is *almost* sufficient
-for timing the RX1 and RX2 downlink windows, but that is only available
-in FSK mode, not in LoRa mode). This means that the microcontroller is
-responsible for keeping track of time. In particular, it should note
-when a packet finished transmitting, so it can open up the RX1 and RX2
-receive windows at a fixed time after the end of transmission.
-
-This timing uses the Arduino `micros()` timer, which has a granularity
-of 4μs and is based on the primary microcontroller clock.  For timing
-events, the tranceiver uses its DIOx pins as interrupt outputs. In the
-current implementation, these pins are not handled by an actual
-interrupt handler, but they are just polled once every LMIC loop,
-resulting in a bit inaccuracy in the timestamping. Also, running
-scheduled jobs (such as opening up the receive windows) is done using a
-polling approach, which might also result in further delays.
-
-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 inacurracy of plus or minus 2.5 symbol times should be
-acceptable.
-
-At the fastest LoRa setting supported by the tranceiver (SF5BW500) a
-single preamble symbol takes 64μs, so the receive window timing should
-be accurate within 160μs (for LoRaWAN this is SF7BW250, needing accuracy
-within 1280μs). This is certainly within a crystal's accuracy, but using
-the internal oscillator is probably not feasible (which is 1% - 10%
-accurate, depending on calibration). This accuracy should also be
-feasible with the polling approach used, provided that the LMIC loop is
-run often enough.
-
-It would be good to properly review this code at some point, since it
-seems that in some places some offsets and corrections are applied that
-might not be appropriate for the Arduino environment. So if reception is
-not working, the timing is something to have a closer look at.
-
-The LMIC library was intended to connect the DIO pins to interrupt
-lines and run code inside the interrupt handler. However, doing this
-opens up an entire can of worms with regard to doing SPI transfers
-inside interrupt routines (some of which is solved by the Arduino
-`beginTransaction()` API, but possibly not everything). One simpler
-alternative could be to use an interrupt handler to just store a
-timestamp, and then do the actual handling in the main loop (this
-requires modifications of the library to pass a timestamp to the LMIC
-`radio_irq_handler()` function).
-
-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.
-Unfortunately, timer0, as used by Arduino's `millis()` and `micros()`
-functions does not seem to have an input capture unit, meaning a
-separate timer is needed for this.
-
-If the main microcontroller does not have a crystal, but uses the
-internal oscillator, the clock output of the transceiver (on DIO5) could
-be usable to drive this timer instead of the main microcontroller clock,
-to ensure the receive window timing is sufficiently accurate. Ideally,
-this would use timer2, which supports asynchronous mode (e.g. running
-while the microcontroller is sleeping), but that timer does not have an
-input capture unit. Timer1 has one, but it seems it will stop running
-once the microcontroller sleeps. Running the microcontroller in idle
-mode with a slower clock might be feasible, though. Instead of using the
-main crystal oscillator of the transceiver, it could be possible to use
-the transceiver's internal RC oscillator (which is calibrated against
-the transceiver crystal), or to calibrate the microcontroller internal
-RC oscillator using the transceiver's clkout. However, that datasheet is
-a bit vague on the RC oscillator's accuracy and how to use it exactly
-(some registers seem to be FSK-mode only), so this needs some
-experiments.
-
-Downlink datarate
------------------
-Note that the datarate used for downlink packets in the RX2 window
-defaults to SF12BW125 according to the specification, but some networks
-use different values (iot.semtech.com and The Things Network both use
-SF9BW). 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.
-
-     LMIC.dn2Dr = DR_SF9;
-
-When using OTAA, the network communicates the RX2 settings in the
-join accept message, but the LMIC library does not currently process

+# Adding a new region to Arduino LMIC
+This variant of the Arduino LMIC code supports adding additional regions beyond the eu868 and us915 bands supoprted by the original IBM LMIC 1.6 code.
+
+This document sketches how to add a new region.
+
+## Planning
+
+### Determine the region/region category
+Compare the target region (in the LoRaWAN regional specification) to the EU868 and US915 regions. There are three possibilities.
+1. the region is like the EU region. There are a limited number of channels (up to 8), and only a small number of channels are used for OTAA join operations. The response masks refer to individual channels, and the JOIN-response can send frequencies of specific channels to be added.
+
+2. The region is like the US region. There are many channels (the US has 64) with fixed frequences, and the channel masks refer to subsets of the fixed channels.
+
+3. The region is not really like either the EU or  US. At the moment, it seems that CN470-510MHz (section 2.6 of LoRaWAN Regional Parameters spec V1.0.2rB) falls into this category.
+
+Bandplans in categories (1) and (2) are easily supported. Bandplans in category (3) are not supoprted by the current code.
+
+### Check whether the region is already listed in `lmic_config_preconditions.h`
+Check `src/lmic/lmic_config_preconditions.h` and scan the `LMIC_REGION_...` definitions. The numeric values are assigned based on the subchapter in section 2 of the LoRaWAN 1.0.2 Regional Parmaters document. If your symbol is already there, then the first part of adaptation has already been done. There will already be a corresponding `CFG_...` symbol. But if your region isn't supported, you'll need to add it here.  
+
+- `LMIC_REGION_myregion` must be a distinct integer, and must be less than 32 (so as to fit into a bitmask)
+
+## Make the appropriate changes in `lmic_config_preconditions.h`
+
+- `LMIC_REGION_SUPPORTED` is a bit mask of all regions supported by the code. Your new region must appear in this list.
+- `CFG_LMIC_REGION_MASK` is a bit mask that, when expanded, returns a bitmask for each defined `CFG_...` variable. You must add your `CFG_myregion` symbol to this list.
+- `CFG_region` evaluates to the `LMIC_REGION_...` value for the selected region (as long as only one region is selected). The header files check for this, so you don't have to.
+- `CFG_LMIC_EU_like_MASK` is a bitmask of regions that are EU-like, and `CFG_LMIC_US_like_MASK` is a bitmask of regions that are US-like. Add your region to the appropriate one of these two variables.
+
+## Document your region in `config.h`
+You'll see where the regions are listed. Add yours.
+
+## Document your region in `README.md`
+You'll see where the regions are listed. Add yours.
+
+## Add the definitions for your region in `lorabase.h`
+- If your region is EU like, copy the EU block. Document any duty-cycle limitations.
+- if your region is US like, copy the US block. 
+- As appropriate, copy `lorabase_eu868.h` or `lorabase_us915.h` to make your own `lorabase_myregion.h`.  Fill in the symbols.
+
+At time of writing, you need to duplicate some code to copy some settings from `..._CONFIG_SYMBOL` to the corresponding `CONFIG_SYMBOL`; and you need to put some region-specific knowledge into the `lorabase.h` header file. The long-term direction is to put all the regional knowledge into the region-specific header, and then the central code will just copy. The architectural impulse is that we'll want to be able to reuse the regional header files in other contexts. On the other hand, because it's error prone, we don't want to `#include` files that aren't being used; otherwise you could accidentally use EU parameters in US code, etc.
+
+- Now's a good time to test-compile and clean out errors introduced. You'll still have problems compiling, but they should look like this:
+    ```
+    lmic.c:29: In file included from
+ 
+    lmic_bandplan.h: 52:3: error: #error "maxFrameLen() not defined by bandplan"
+       # error "maxFrameLen() not defined by bandplan"
+ 
+    lmic_bandplan.h: 56:3: error: #error "pow2dBm() not defined by bandplan"
+       # error "pow2dBm() not defined by bandplan"
+    ```
+
+## Edit `lmic_bandplan.h`
+The next step is to add the region-specific interfaces for your region.
+
+Do this by editing `lmic_bandplan.h` and adding the appropriate call to a (new) region-specific file `lmic_bandplan_myregion.h`, where "myregion" is the abbreviation for your region.
+
+Then, if your region is eu868-like, copy `lmic_bandplan_eu868.h` to create your new region-specific header file; otherwise copy `lmic_bandplan_us915.h`.
+
+## Create `lmic_myregion.c`
+Once again, you will start by copying either `lmic_eu868.c` or `lmic_us915.c` to create your new file. Then touch it up as necessary.
+
+## General Discussion
+- You'll find it easier to do the test compiles using the example scripts in this directory, rather than trying to get all the Catena framework going too. On the other hand, working with the Catena framework will expose more problems.
+
+## Addding the region to the Arduino_LoRaWAN library
+
+In `Arduino_LoRaWAN_ttn.h`:
+- Add a new class with name `Arduino_LoRaWAN_ttn_myregion`, copied either from the `Arduino_LoRaWAN_ttn_eu868` class or the `Arduino_LoRaWAN_ttn_us915` class.
+- Extend the list of `#if defined(CFG_eu868)` etc to define `Arduino_LoRaWAN_REGION_TAG` to the suffix of your new class if `CFG_myregion` is defined.
+
+Then copy either `ttn_eu868_netbegin.cpp`/`ttn_eu868_netjoin.cpp` or `ttn_us915_netbegin.cpp`/`ttn_us915_netjoin.cpp` to make your own file(s) for the key functions.
