I just got a pair of the free drum sensors and quite excited to experiment with it!
I charged the sensors and turned it on to connect to my app/windows 10 system. But when I turn on one of the sensors, the led light is constanly changing from blue to green to red. I’m not sure how to fix this and I couldn’t find a solution yet. I tried resetting the sensor by long press, but this persists. Your help would be great.
