Hi! I have just received my first sonoff, and tested it quickly. Rf433 works fine but I can not configure the wifi link. I have installed the Android app and long click the sonoff button. I can even see the sonoff network name.But the app does not connect to my sonoff. It just shows a countdown and ends up with a timeout. My smartphone is a Motorola X play with android 6. I think these sonoffs are a little wonder. Please give some clues to help debugging this weird behaviour.
