Is it possible to get the RGB LED and BLE to work at the same time?
As soon as I try to change the RGB colors it kills BLE scanning.
Not sure if this is it, but something to maybe look into (until somebody with more knowledge replies)...
I know back when I was playing with some combo projects on my UNO, I had some conflicts between timers used by libraries as well as the PWM pins. Here's a link with some related discussion (not exactly your case though):
My fix was to just use a different pin for the conflicting LED pin.
Good luck!
its pretty Hard to answer without a code or wiring diagram to look for any reason...
