Adafruit fork of the Arduino NINA-W102 firmware

Build Status

This is the Adafruit fork of the Arduino NINA-W102 firmware. The original repository is located at https://github.com/arduino/nina-fw

This firmware uses Espressif's IDF

The NINA firmware version needs to be updated in four places in this repo:

  1. CommandHandler.cpp
  2. combine.py
  3. Makefile
  4. CHANGELOG

Building

The firmware shipped in Adafruit's products is compiled following these instructions. These may differ from the instructions included in the original Arduino firmware repository.

  1. Download the ESP32 toolchain
  2. Extract it and add it to your PATH: export PATH=$PATH:<path/to/toolchain>/bin
  3. Clone v3.3.1 of the IDF: git clone --branch v3.3.1 --recursive https://github.com/espressif/esp-idf.git
  4. Set the IDF_PATH environment variable: export IDF_PATH=<path/to/idf>
  5. Run make firmware to build the firmware (in the directory of this read me)
  6. You should have a file named NINA_W102-x.x.x.bin in the top directory
  7. Use appropriate tools (esptool.py, appropriate pass-through firmware etc) to load this binary file onto your board. a. If you do not know how to do this, we have an excellent guide on the Adafruit Learning System for upgrading your ESP32's firmware
