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

Build a new certificate list (based on the Google Android root CA list)

git clone https://android.googlesource.com/platform/system/ca-certificates
cp nina-fw/tools/nina-fw-create-roots.sh ca-certificates/files
cd ca-certificates/files
./nina-fw-create-roots.sh
cp roots.pem ../../nina-fw/data/roots.pem

Check certificate list against URL list

cd tools
./sslcheck.sh -c ../data/roots.pem -l url_lists/url_list_moz.com.txt -e
