Hi
I think that this forum is trying to solve two different problems. For the server problem when only the first connection can be established I think could be a SDP problem and it is described at:

Advice on managing connections between Bluetooth SDP records and a game server

How ever I also have problems with the Bluetooth that occasionally stops working and forces me to restart the phone to be able to reconnect the Bluetooth connection. I have a background midlet that reads data from a Bluetooth GPS and sends it to a server. This works fine but in some time between 8-72 hours the Bluetooth hangs and I have to restart the phone. The exception that is thrown is a “security block”. How ever that exception can be thrown earlier and don't block the communication. So what I can se the security exception does not always lead to a blocked connection. I would appreciate any ideas about this.
