Hold initial code for micropython and lorawan

uPyLoraWAN

The ESP32 and M5Stack using MicroPython meet LoRaWAN.

Setup

Use VSCode and the PyMakr extension to upload the code. If you are new on MicroPython, this tutorial can help you to install the firmware on a ESP32.

Follow these steps to deploy the project:

1. Rename the file config.sample.py to config.py
2. Configure the SPI pins to connect to the SX127x module. I've included the following example connections:
   • ES32 TTGO v1.0
   • M5Stack ATOM connected to LoRa v2.0 board.
   • M5Stack Fire connected to the LoRa868 Module.
3. Configure the devaddr, nwkey, and app of the ttn_config variable following the instruction from this link.

Hardware

• Wemos® TTGO LORA32 868/915Mhz board.
• M5Stack ATOM connected to LoRa v2.0 board. M5Stack Fire connected to the LoRa868 Module.
