    • Sketch -> Include Library -> Manage Libraries
    • Search for "LoRa" (LoRa by Sandeep Mistry) -> Install
  • After installing the libraries copy and paste the LoRa_TRX.ino file into your Adurino IDE
  • Before flashing the firmware set the right frequency config in line 23 and the right borad config in line 26 - 29.
    • Currently supported boads: TTGO T-Beam V1, TTGO LoRa32 V1, TTGO LoRa32 V2.1
  • Compile it and upload to the board

Usage

  • Sending and receiving messages is done via serial communication over Bluetooth.
  • Pair your Smartphone with the ESP32 LoRa-Board.
  • Download a Serial Bluetooth Terminal APP and chose your previously paired device for serial communication.
  • Once you are connected you can start sending and receiving messages over LoRa direct on your cellphone.
