ESP32 LoRa APRS Modem

This project is amateur radio ESP32 based LoRa KISS Bluetooth/BLE/USB/TCPIP modem + LoRa APRS-IS RX/TX iGate server over WiFI + LoRa APRS digipeater + Codec2 DV modem (with Codec2 Talkie Android application).

⚠ To configure sketch modify default parameters in config.h file.

For project description, detailed setup and more information, please, visit our Wiki at https://github.com/sh123/esp32_loraprs/wiki
For discussions, visit https://github.com/sh123/esp32_loraprs/discussions

⚠ Project also supports APRSDroid TNC2 text APRS packet mode (configurable), which makes it interoperable with other LoRa APRS trackers without AX25 support.

Supported module types: SX126X, SX127X and other modules supported by RadioLib.

Modules, which are used by users and known to work

SX126X
- E22-400M30S
- E220-400M30S (LLCC68) BW125 SF from 7 to 9 (chip limitations)
SX127X
- RA-01
