This is a fairly simple add-on for mobile phones to enable SMS-like messaging in a group when outside cell coverage, or in disaster scenarios. It utilises Semtech LoRa radios, for low-power/long-range communications. There are a lot of hardware options, and I am still trying different devices and manufacturers, but for now this tutorial will show how to assemble and setup one of the following boards:

  • TTGO ESP32 Lora with OLED
  • Adafruit Feather M0 RFM96

do you sell LoRa mesh chat?

Systemkiller2000

Hello,

i like this project and i want to build up a Lora Mesh Messenger, but i am new in this.
I have those devices:

2 Pieces ESP32 Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores ESP32s Antenna Module Board for Arduino IDE

2 Pieces lorawan transceiver RF LoRa module SX1276 chip nrf52832 radio comunicador de longo alcance communication Receiver and Transmitter

I don’t want to use an ESP32 Board with OLED Display. I want to use the Ripple App to chat.

But i don’t know how to wire it correctly and also i have not really an idea how to set up the right software.

Could you help me?

Many thanks and best regards
