Sounds through Bluetooth

I use BluetoothClient to connect to a headphone.
AI tell me he is connected but my headphone doesn't...and i sounds are not send to it.
If I look in bluetooth in Android it doesn't seems to be connected.

Connect_BT.aia (418,6 Ko)

Is someone has an Idea about what is my problem ?

I used this configuration in a Dodocool and it worked for me.

No. it doesn't works for me: connect response is false...

I can connect my headphone clicking in BT android screen or using for exemple "Macrodroi", but i don't succed to do it with AI !
