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 (suggested, 1W modules will provide decent coverage for APRS, stable frequency suitable for < 125 kHz BW at 433 MHz, 5V from USB power bank is enough to power it, has additional LNA)
- 👍 E22-400M30S (SX1268)
- E220-400M30S (LLCC68) BW125 SF from 7 to 9 (chip limitations)
- These modules are 30dbm modules, but maximum power should be set to no more than 20-22dbm, see https://github.com/jgromes/RadioLib/wiki/High-power-Radio-Modules-Guide
- SX127X (low power, 50-100mW, temperature frequency drift, problematic for narrow band)
- RA-01 (SX1278)
- RA-02 (SX1276)
- TTGO T-Beam (SX1276)
