    Using Bluetooth GPS on Fedora ?


    I have a Dell Inspiron running Fedora 9 and a Garmin GLO Bluetooth GPS/GLONASS gadget.

    I'd like to be able to read the GPS data.
    I've tried a few HOWTOs without success.

    Bluetooth on the Dell is basically working - I can push files to my phone and use it as a modem. The GLO works with my Nokia E71 phone and my Nokia N810 (Maemon Linux) tablet..

    Code:
    # hcitool scan
    Scanning ...
    	10:xx:xx:xx:xx:xx Garmin GLO #65e4e
    
    # sdptool browse 10:xx:xx:xx:xx:xx
    Browsing 10:xx:xx:xx:xx:xx

    Can't connect RFCOMM socket: Operation now in progress
    # rfcomm connect 5 10:xx:xx:xx:xx:xx 3
    Can't connect RFCOMM socket: Operation now in progress
    # rfcomm connect 5 10:xx:xx:xx:xx:xx 4
    Can't connect RFCOMM socket: Connection refused
    
    # sdptool add --channel=1 OPUSH
    OBEX Object Push service registered
    # cat /dev/rfcomm5
    cat: /dev/rfcomm5: Connection refused
    I tried setting /etc/bluetooth/hcid.conf and /etc/bluetooth/rfcomm.conf
    with e.g. "class 0x3e0100" and "security none" per a HOWTO without any luck.

    Nothing relevant in /var/log/messages or dmesg

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    Well, the system probably sees it as a USB serial device. You can use just about any software to read it, but interpreting the data (if in binary form) may be an issue. Without having a copy of the device, I really cannot advise you further.
    Sometimes, real fast is almost as good as real time.

    When I connect e.g. a serial/USB converter, there's an entry in syslog about TTYUSB0 etc. For the GPS, there's nothing.
