How to detect bluetooth connectoin exist or not?

Hi All,
we can initial/close a bluetooth connection, if user pause my
program to do other work and then back to my program, how can I detect
the bluetooth connection exist or not?

Should I add check routine in run()?

Best regards,
Boki.

Well, how does one usually solve the lost connection problem? *g*
If you connect to a server and then you don't send data for an extended
period of time, the server will kick you.
Usually one should have a timer mechanism that continuosly sends packets
from the sender to show the counterpart that you are still there. This
doesn't have to be done every 10ms, once every 5 min or so should be
enough, provided you don't move your bluetooth stuff too much in and out
of the reception area.

Either that or you have a separate thread the accesses the then
shared(!) file pointer, sends a short ping and sleeps for 5min.
Closing and opening connections for every send would be another option,
but it depends among other things on what characteristics your traffic has.

1. If Sony Ericsson devices, try to hang up it.
2. Tell your bluetooth firmware.

public boolean processEvents(InputStream is, OutputStream os) {
try {

int bytesToRead = is.available();
...
}


Throws:
