Hi,
I'm trying to open an RFCOMM connection from my android device to my
desktop pc running Ubuntu 10.04, send some data, close the connection
and then do it again. My desktop program is written in Java and relies
on BlueCove[1] to handle bluetooth details which calls Bluez 4.x in
this case.
The problem is that I get a successful connection and data transfer in
the first communication attempt but nothing in subsequent attempts.
There is this thread[2] in the android-platform mailing list with much
more detail, but I think you could just take a look at this hcidump
that has been requested there to let me know if this is a problem in
bluez on the android or desktop side:

Please, let me know if you need more info.
The same program works perfectly when the android application connects
to it running on Windows 7 using the Microsoft Bluetooth Stack.

So, any ideas? Don't you find it strange that bluez can't communicate
with itself?
