I managed to get my first Core working and it all worked fine. Then I have my second one. Followed the same setup - power up, fire up App, write the WiFi details - all good. It flashed green… and that was it… kept flashing… infinitely.
I’ve restarted the app, cleared memory, unplugged USB multiple times. I’ve also tried setting it up over USB to manually set the SSID and password. No luck. It doesn’t seem to be able to connect to WiFi.
Powered via 1A output charger, next to my WiFi.
Note: My other Core ( I have 2 ) works fine. I can write new code via online IDE upload, etc. All good. On this very same network.
