could be. i'm no expert in GPS, sorry. i've seen a couple of GPS receivers
and the high-level protocol is simple - just ASCII strings. it should be
very easy to figure it out - just need a serial port snooper :)

it does not work like this, sorry. Serial Port Profiles is based on RFCOMM.
RFCOMM in its turn based on L2CAP, L2CAP on HCI, etc. so you need to port
entire stack back to 4.8-R. i barely have time to keep -current development
going. i missied my deadlines few times already :-( if you have time to port
the code back to 4.8 i can offer my help.
