Hardware Arduino WiFi Rev2

ZainS:
Is 1.2.2 released as yet?

It depends on what you mean by "released".

There are three components to that question:

  • Has there been a release of the NINA firmware? I would say "yes" (actually there is even a 1.2.3 now), though the developers haven't created Git tags in that repository since the 1.1.0 release for some reason.
  • Has there been a release of the WiFi101/WiFi NINA Firmware Updater plugin for the Arduino IDE which contains NINA firmware 1.2.2? Yes. The 0.10.7 release of the plugin contains NINA firmware 1.2.2. The 0.10.8 release of the plugin contains NINA firmware 1.2.3.
  • Has there been a release of the Arduino IDE which contains WiFi101/WiFi NINA Firmware Updater plugin 0.10.7 or newer? No. There has not been an Arduino IDE release since the time that WiFi NINA 1.2.2 came out. It is part of the Arduino IDE hourly build though.
