I guess most people will buy a GPS receiver to use it with Maemo-mapper so it would be helpful to describe on the Maemo-mapper site (and in this thread) how to pair/connect the GPS receiver to the N770. My first attempt was to use the BT wizard to pair but this failed. Then I used the Maemo Bluetooth Plugin which picked it up and dislayed the MAC address. I then had to manually type this address in Maemo-mapper because it was set to 00:00:00:00:00:00 as I was using it without a GPS receiver. Once the MAC address was set, all I do is to start Maemo-mapper and it connects automatically, ie. I don't have to Connect in the Maemo Bluetooth Plugin. Interestingly the BT phone icon at the top changes, showing that a BT "phone" is connected.

It sounds that the previous 00:00:00:00:00:00 value and the presence of the Maemo Bluetooth Plugin confuse the program, probably none of this messing is necessary if Maemo-mapper is ran first time when a GPS receiver is already running.

Most of us here are of the experimenting type but it would be useful to document how to connect the BT receiver. Probably even better, the code might be changed so that it picks up the receiver without any manual intervention.

I am hooked on Maemo-mapper... what a program!
