This one has me a little confused. My PBV3 works fine when I reset it or put it in AP mode. As soon as I connect it to wifi in client mode, there is no output. It works fine otherwise, and I can change everything, and have tried changing everything that might make the output not work, but all the settings carry over between resets other than WiFi, so I don’t think any setting is causing it.
I’ve gone through the process a few times resetting it, putting it in AP mode, checking that it works, resetting, putting it into client mode, confirming that it still doesn’t work, and then going back to AP mode, and having it work perfectly.
