Question

Hi
I’m trying to implement a bluetooth library and in it I want to connect an rfcomm socket once and then reuse it on all calls.
I want to know if it’s connected or not in order to know if I should call the connect method.
I can’t find anything in the source code for Bluetooth sockets since it’s all native calls and there’s no isConnected method defined in the API…
Does anyone have any experience with this?

I think you would have a member variable maintain the state of your connection. on successful connection set it to true, start a thread that loops always reading bytes from the sockets inputstream and if you get an IOException on that thread, set your flag to false.
