    How to rfcomm bind /dev/bluetooth/rfcomm0 ?


    how to bind rfcomm to rfcomm0 device ?
    is sudo necessary or required ?

    I get
    [admin@oo root]$ rfcomm
    rfcomm0: 00:15:4B:01:2E:BD channel 1 closed

    bt GPS is not connected.

    get gps connected

    [admin@oo root]$ hcitool connect 00:15:4B:01:2E:BD
    < ACL 00:15:4B:01:2E:BD handle 6 state 1 lm MASTER
    [admin@oo root]$

    and the same message

    [admin@oo root]$ rfcomm

    sudo doesn't exist on the oleg
    try setting your admin to root in the webinterface, it might work

    follow-up 2

    finally get my bluetooth gps connected
    and can read NMEA sentences in terminal.

    Now I am looking for basic NMEA parser to extract lon, lat, time, speed
    None in IPKG.

    Maybe shell script parser .
    Any idea ?

    gpsd and gpspipe - no NMEA sentences, why ?


    I can read NMEA sentences from Bluetooth GPS device
    cat reading binded rfcomm0 device.

    I wanted the same with gpsd.

    gpsd /dev/rfcomm0
    and no NMEA entences,
    why ?

    From previous thread I have learned, gpsd worked with usb-serial Prolific device.
    Any chance to have gpsd to work with rfcomm .
    If so, how to set up gpsd.

    I would prefer gpsd as it comes with some parameters to read long, lat, time, speed.


  7. #7

    got a hint from Gary Miller, author of gpspipe
    and gpsd started to work finally
    sending NMEA sentences to stdout - terminal.

    I need to learn more how to use gpsd to select long, lat, time, speed data only.

    Can you help me or refer to some nice examples ?


  8. #8

    gpsd and gpspipe work fine, showing up NMEA sentences

    follow -up

    finally got gpsd and gpspipe working
    showing up
    NMEA sentences in 2 opened terminal sessions respectively.


    Have a Happy New Year 2009

    How to start request protocol for gpsd client ?


    I can run gpsd in debug mode 5, gpspipe works normally.

    What I am looking for is how to switch gpsd to interactive mode,
    to read request protocol .

    Each request normally consists of a single ASCII character followed by a newline

    Best approach for sharing GPS over Ethernet

    Hi folks, first post!

    I'm looking for the fastest and safest approach to incorporating a GPS receiver into an Asus router. I simply want it to be available over the wired network and it seems that using a standard USB GPS receiver and installing gpsd on the router is the best way to do this.

    I'm comfortable with Linux and custom electronics, but was really hoping I could avoid some risk by consulting those that had come before me. Has anyone gone down this route and would be willing to share details?
