Check WiFiNINA Firmware Version

This tutorial will guide you in the process of assessing the firmware release of your Arduino UNO WiFi Rev.2, Arduino MKR 1010 and Arduino MKR VIDOR 4000. It is important to check firmware version against WiFiNNINA library version so that they are both aligned. Having different versions of library and firmware may create compatibility issues.

Hardware required

Arduino UNO WiFi Rev.2, Arduino MKR 1010 or Arduino MKR VIDOR 4000

Circuit

The board should be connected to the USB port of the computer.

Code

When you load the sketch on the board, it will wait for a serial monitor console to be opened on your computer, then it prints out the result of the check between the expected firmware and the one available. If everything is fine, then you can proceed with your tasks, otherwise you should update the firmware following this update procedure.

CheckFW OK
