Mark Read Well-Known Member Licensed User Longtime User Feb 1, 2016 #3 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? Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Feb 1, 2016 #4 Terminated is called when the connection is closed by the other side. Practically you should handle both cases in the same way. Upvote 0

Mark Read Well-Known Member Licensed User Longtime User Feb 1, 2016 #5 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.
