You need to handle AStream_Error and AStream_Terminated events.

Okay. I can imagine that the Astream_Error would be called if data cannot be sent to the client but when is Astream_Terminated called?

Terminated is called when the connection is closed by the other side. Practically you should handle both cases in the same way.

So to sum up:

RPi sends data continuously to a tablet. Tablet listens for data.

RPi cannot send data over bluetooth - AStreams_Error will be called on RPi.
Tablet closes bluetooth - AStreams_Terminated is called on RPi.
Correct?

What error deos the tablet generate?

Thanks Erel.

Yes (errors can happen even if nothing is written).

Thanks for the clear explanation Erel. Have added the two subs on my tablet and RPi. Now I can reconnect if the bluetooth connection is lost, without restarting both Apps!
