# Arduino NINA-W102 firmware This firmware uses [Espressif's IDF](https://github.com/espressif/esp-idf) ## Building 1. [Download the ESP32 toolchain](http://esp-idf.readthedocs.io/en/v3.1/get-started/index.html#setup-toolchain) 1. Extract it and add it to your `PATH`: `export PATH=$PATH:/bin` 1. Clone **v3.1** of the IDF: `git clone --branch v3.1 --recursive https://github.com/espressif/esp-idf.git` 1. Set the `IDF_PATH` environment variable: `export IDF_PATH=` 1. Run `make` to build the firmware (in the directory of this read me) 1. Load the `Tools -> SerialNINAPassthrough` example sketch on to the board 1. Use `esptool` to flash the compiled firmware ## License Copyright (c) 2018 Arduino SA. All rights reserved.
