The pico-wifi-settings setup app has an interactive, text mode user interface which you can access by USB. Once installed on your Pico, it allows you to search for WiFi hotspots and create/edit the WiFi settings file. This release package contains pre-built UF2 firmware files for Pico W and Pico 2 W.
Version 0.3.1 fixes a bug preventing OTA updates on devices with a short watchdog time: new firmware could be downloaded but not installed, as the verification process would cause the watchdog timer to overflow.
