Hello, I have some problem with BLE and arduino communication. I can send string from my phone to arduino bluetooth module (HM 10), but from arduino to phone I receive only unusual characters.  
Any solution about that?  
Thanks

Don’t spam the forum by creating multiple topics about the same thing.

Anyway, do you have any suggestions to solve my problem?
