Re: 32d fails to connect bt speaker when power anyting but micro usb

I do power it with 3.3v. Have tried with. 5 v also same problem

Only time I don’t have problem is if I power into micro usb


I’m not using WiFi I know they can’t coexist

The problem resolved if I push reset on board I have used a cap from en to ground thst did nothing
