Hello guys,

I have made some progress, but it's not working yet.
I'd appreciate any help.

Achievements :
1. Python file listening on bluetooth
2. Same file also activates location service and gets gps data.
3. The python file send that over bluetooth everytime there is a fix change.
4. Manage to see the bluetooth server from my N95, choose it as external gps, but it halts after 3 seconds, asking again for an external gps - hence it doesn't like what it's getting.

Thing I need help with :
1. Something with my check sums is wrong, wrong python syntax or something, don't know.
2. If I remove the checksums, as they are supposed to be optional this still doesn't work.
3. Need a way to detect that N95 disconnected and stop everything, and not with an exception, i want the script to keep running.
4. Does anyone know if the N95 must receive all types of GTXXX messages, or will it do with just some?

If there is a python guru which knows his gps who can help me,
Please do. I'll be grateful.

P.s. The file is mostly copy pastes from stuff I found on the net,
90% not my work, I am just putting it all together for N900.
It's attached here.
