LoRa_Parrot

Its a proof of concept to realize a LoRa Repeater/Parrot on ESP32 LoRa Boards.

Installation

Using Arduino IDE:

• Install ESP32 Boards on Arduino IDE
  • Install instructions for the ESP32 Board
• Install OLED Libraries
  • Sketch -> Include Library -> Manage Libraries
  • Search for "SSD1306" from Adafruit in Library Manager -> Install
  • Search for "GFX Library" from Adafruit in Library Manager -> Install
• Install LoRa Library for Semtech SX1276/77/78/79
  • 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 17, "URCALL" or ID in line 90 and the right borad config in line 21 - 24.
  • Currently supported boads: TTGO T-Beam V1, TTGO LoRa32 V1, TTGO LoRa32 V2.1
• Compile it and upload to the board

Usage

• The parrot repeats everything that has ">>" in the message. Without ">>" the packet will be ignored
• You have to assign an ID / CALL to the parrot (before compiling and flashing).
• The parrot adds "(Parrot: URCALL_1 / ID)" to the retransmitted package.
• The parrot (with same ID / CALL) cannot retransmit itself to prevent loops.
