Bluetooth implementation on the micro:bit is a bit confusing to say at least ;-)
Lets try to deal with the most common problems:
1. Pairing the board - you dont have to!
2. My board is not discoverable - this is a bit tricky but there is a way to fix it
3. Memory problems - on Micro:Bit v1 and v1.5
4. Naming - how to know what board to connect when your app sees 20 micro:bits at once
Hope it helps!
