Arduino library for LoRa communication with Semtech SX126x chips. It is based on Semtech's SX126x libraries and adapted to the Arduino framework for ESP32, ESP8266, nRF52832 and RP2040. It will not work with other uC's like AVR.

- Add addional bandwidths for LoRa transmissions. Breaks
Radio.TimeOnAir()for bandwidths other than BW 125, 250 and 500 - Fix minor problem in CF list handling for AS923-x regions
- Implement new regions AS923-2, AS923-3, AS923-4, RU864

- When OTAA join failed callback was called, following lmh_join() calls fail always
- Add callback for OTAA join failure
- Fix ADR problem
- Fix Join problem for some Regions
- Add some debug output
- Add option to set node class during initialization. Defaults to CLASS_A for backward compatibility:
lmh_error_status lmh_init(lmh_callback_t *callbacks, lmh_param_t lora_param, bool otaa, eDeviceClass class = CLASS_A);
- Fix wrong control of antenna switch for RAK4631
- Add option to control power of antenna switch by the library with
_hwConfig.USE_RXEN_ANT_PWR
- Duty cycle and adaptive data rate control moved out of Commissioning.h
- Fixed linker error when header files are included from multiple source files
- Support for RAKwireless RAK4630 module finished
V1.1.3 Improve LoRaWan implementation (special thanks to RAKwireless who did a lot of testing with the library)
- Rework the timer functions for nRF52 family. OTAA now working better
- Add option to select between OTAA and ABP for LoRaWan when calling
lmh_init() - Reworked SX126x reset function
- Support for RAKwireless RAK4630/4631 modules =>
lora_rak4630_init() - Update region settings
Commissioning.hneeds only to be edited for the region. All other LoRaWan settings can be done now from the application side.
