Hello,
I have been doing some Bluetooth SPP development with an HTC Legend
which was working just fine.
Today I received my HTC Desire and I cant get an SPP connection to
work.
The first thing I had to do is remove the mAdapter.cancelDiscovery()
call in the connectThread().
It seems there is some sort of timing issue here and with the faster
processor its not working like this.
Below is an extract from the logs when mAdapter.cancelDiscovery() was
being called just prior to mmSocket.connect();

I get a little farther after this change and it almost seems as if the
connection is up because the BT Icon on my laptop changes to green but
then the connection fails anyway.
Here is an extract of the stack after the call to mmSocket.connect();

So basically it fails with a java.io.IOException: Service discovery
failed.... I have no idea why.
Anyone have any ideas?
Thanks,
Serge
