Volume up-down with android

[Epasta]

Hi, I have implemented a music control button.

This button can send (volume+, volume-, play music, stop music and my custom control (0x06) for my app ).

Procedure: pairing android and button; now i press the button for music control and all is ok, all functions works perfectly!

Now I turn off the board (or i turn off the bluetooth on android phone; is the same)

Music control notification does not works, when i send this notifications the chip restart; but if i send my custom notification works perfectly!

I have to redo the pairing procedure and all works perfectly!

On iPhone I don't have any problem, I can connect and disconnect 1000 times that woks perfectly!

I do not understand why...

Sdk 10.0.0; SoftDevice 8.0.0; Chip nrf51822;

Someone can halpme?!

thanks for the reply and the time! Enrico

Can you capture a sniffer trace showing the pairing and also the failing connection?

Note that there are a couple of examples for this here and here.
