How to upload certificates on UNO R4 WiFi?

Hello, I would like to use the WiFiSSLClient with my UNO R4 WiFi, but I can't use the "Firmware Updater" or "Certificate Uploader" in the IDE because the board seems to be incompatible. What now?

Hi @baumxyz. You can use the "Arduino Firmware Uploader" command line tool:

Work is also in progress to add UNO R4 WiFi support to the firmware updater and certificate uploader features of Arduino IDE:

That should be available in the nightly build of Arduino IDE within the next few days.


Please let me know if you have any questions or problems while following those instructions.
