Arduino NINA-W102 firmware

This firmware uses Espressif's IDF

Building

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 to build the firmware (in the directory of this read me)
6. Load the Tools -> SerialNINAPassthrough example sketch on to the board
7. Use esptool to flash the compiled firmware

Notes

If updating Arduino UNO WiFi Rev. 2 NINA firmware via SerialNINAPassthrough sketch then the esptool invocation needs to be changed slightly:

-  --baud 115200 --before default_reset
+  --baud 115200 --before no_reset
