Hi - yes I've tried resetting the bluetooth and clearing the memory. Unfortunately BIAB only works with the wired version.
I have also read up on the wired verson - it does not provide MIDI output to any apps. I've seen one individual however place a fretlight wireless neck and hardware onto a midi capable guitar. The wired version could possibly be done too (although they would be two separate attachments).

Ultimately I've tried the Fretlight for a week and I have too many problems to enjoy it. I'm going to put it up for sale.

Issue 1: The pickups screetch with loud noise any time an LED lights up.
Issue 2: The wireless bluetooth disonnects if I'm more than 3-4 ft from a receiver. It has also disconnected if I hit the body of the guitar too hard with my picking hand.
Issue 3: I just cannot see the LEDs unless I turn the guitar neck to face me (which is not ideal for playing). If I hold the guitar in a playable position the strings block the LED lights so that I cannot tell which string the LED is telling me to fret.

I wish it would have worked out for learning scales. But I've found it to be a bit of a headache.
