USB Serial

This has not been reported to work with Linux, it causes these errors:

Bluetooth Serial

Plug in your bluetooth adaptor, turn it on, or otherwise make sure it's ready for use. Once you're ready use hcitool to scan for available devices as follows.

robert@The-Pandora:~/workspace/C++Test$ hcitool scan
Scanning ...
        <<your device's mac>>       HOLUX_M-1000

Now you have the information to proceed, edit /etc/bluetooth/rfcomm.conf and use the following:

rfcomm1 {
        bind yes;
        device <<your device's mac>>;
        comment "Holux M-1000 serial.";
}

This will enable you to point gpsd to /dev/rfcomm1

gpsd /dev/rfcomm1

Now you can use gpsd as you wish. If you want to do a quick test you can open /dev/rfcomm1 in cutecom or just with cat, it seems to generally auto-initialise itself with the right baud rate (any multiple of 600 it seems). You'll get a few lines starting with $GPGSV, $GPRMC, $GPVTG, $GPGGA, and/or $GPRMC; if so then everything is working well!
