## Release History
|
||||
|
||||
- Interim bug fixes: added a new API (`radio_irq_handler_v2()`), which allows the caller to provide the timestamp of the interrupt. This allows for more accurate timing, because the knowledge of interrupt overhead can be moved to a platform-specific layer ([#148](https://github.com/mcci-catena/arduino-lmic/issues/148)). Fixed compile issues on ESP32 ([#140](https://github.com/mcci-catena/arduino-lmic/issues/140) and [#153](https://github.com/mcci-catena/arduino-lmic/issues/150)). We added ESP32 and 32u4 as targets in CI testing. We switched CI testing to Arduino IDE 1.8.7.
|
||||
Fixed issue [#161](https://github.com/mcci-catena/arduino-lmic/issues/161) selecting the Japan version of as923 using `CFG_as923jp` (selecting via `CFG_as923` and `LMIC_COUNTRY_CODE=LMIC_COUNTRY_CODE_JP` worked).
|
||||
Fixed [#38](https://github.com/mcci-catena/arduino-lmic/issues/38) -- now any call to hal_init() will put the NSS line in the idle (high/inactive) state. As a side effect, RXTX is initialized, and RESET code changed to set value before transitioning state. Likely no net effect, but certainly more correct.
|
||||
|
||||
- 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)).

*
|

* This example sends a valid LoRaWAN packet with payload "Hello,
|

* world!", using frequency and encryption settings matching those of
|
||||
* the The Things Network.
|
||||
*
|
||||
* This uses ABP (Activation-by-personalisation), where a DevAddr and
|
||||
* Session keys are preconfigured (unlike OTAA, where a DevEUI and
|
||||
* application key is configured, while the DevAddr and session keys are
|
||||
* assigned/generated in the over-the-air-activation procedure).
|
||||
*
|
||||
* Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
|
||||
* g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
|
||||
* violated by this sketch when left running for longer)!
|
||||
*
|
||||
* To use this sketch, first register your application and device with
|
||||
* the things network, to set or generate a DevAddr, NwkSKey and
|
||||
* AppSKey. Each device should have their own unique values for these
|
||||
* fields.
|
||||
*
|
||||
* Do not forget to define the radio type correctly in
|
||||
* arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.

* NO WARRANTY OF ANY KIND IS PROVIDED.
|

*
|
||||
* This example sends a valid LoRaWAN packet with payload "Hello,
|
||||
* world!", using frequency and encryption settings matching those of
|
||||
* the The Things Network. It's pre-configured for the Adafruit
|
||||
* Feather M0 LoRa.
|
||||
*
|
||||
* This uses OTAA (Over-the-air activation), where where a DevEUI and
|
||||
* application key is configured, which are used in an over-the-air
|
||||
* activation procedure where a DevAddr and session keys are
|
||||
* assigned/generated for use with all further communication.
|
||||
*
|
||||
* Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
|
||||
* g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
|
||||
* violated by this sketch when left running for longer)!
|
||||
|
||||
* To use this sketch, first register your application and device with
|
||||
* the things network, to set or generate an AppEUI, DevEUI and AppKey.
|
||||
* Multiple devices can use the same AppEUI, but each device has its own
|
||||
* DevEUI and AppKey.
|
||||
*
|
||||
* Do not forget to define the radio type correctly in
|
||||
* arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.

* NO WARRANTY OF ANY KIND IS PROVIDED.
|

*
|
||||
* This example sends a valid LoRaWAN packet with payload "Hello,
|
||||
* world!", using frequency and encryption settings matching those of
|
||||
* the The Things Network.
|
||||
*
|
||||
* This uses OTAA (Over-the-air activation), where where a DevEUI and
|
||||
* application key is configured, which are used in an over-the-air
|
||||
* activation procedure where a DevAddr and session keys are
|
||||
* assigned/generated for use with all further communication.
|
||||
*
|
||||
* Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
|
||||
* g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
|
||||
* violated by this sketch when left running for longer)!
|
||||
|
||||
* To use this sketch, first register your application and device with
|
||||
* the things network, to set or generate an AppEUI, DevEUI and AppKey.
|
||||
* Multiple devices can use the same AppEUI, but each device has its own
|
||||
* DevEUI and AppKey.
|
||||
*
|
||||
* Do not forget to define the radio type correctly in
|
||||
* arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.
