Steps:

1. Start advertising from first device
2. Pair and connect as a second device
3. call Characteristic.write([0x12, 0x34]) from second device
   And crashes in first advertisible device

Please help me!

@alisherbu seems like the characteristic write handler callback is executing on main thread
you can try to wrap this
with handler.post {} like this
If it works fine for you, the please send a PullRequest for this Fix
