  • 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.
