Some Armadeus/Opossom SOM are shipped with u-blox chips for GPS functionnality; as these chips have custom tools, they will be detailed here.

Tools installation

  • To benefit from u-blox custom features, you have to activate them in gpsd:
$ make menuconfig
Target packages  --->
    ...
    Hardware handling  --->
        ..
        [*] gpsd  --->
            ..
            [*]   install python tools (ubxtool, python-gps, etc...)
            *** Protocols ***
            ...
            [*]   UBX
  • rebuild rootfs, reflash, you know ;-)

Usage

  • In following examples $SERIAL_DEV is the serial port device on which the GPS is connected (/dev/ttyXXX)
  • Show current NMEA config/version:
# ubxtool -p CFG-NMEA
  • Activate NMEA 4.1 protocol (on NEO-8M):
# gpsctl -t u-blox -D 5 -b -x "\x06\x17\x00\x41\x00\x02\x00\x00\x00\x00\x00\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00" $SERIAL_DEV
  • Switch u-blox module to UBX binary frame format:
# gpsctl -t u-blox -b $SERIAL_DEV
  • Switch u-blox module to ascii NMEA frame format:
# gpsctl -t u-blox -n $SERIAL_DEV
  • Show current GNNS config:
# ubxtool -p CFG-GNSS
  • Activate/deactivate Glonass:
# ubxtool -e/-d GLONASS
  • Activate/deactivate Galileo:
# ubxtool -e/-d GALILEO
  • Shows Galileo time status (galTOW):
# ubxtool -p NAV-TIMEGAL
  • Activate/deactivate GPS:
# ubxtool -e/-d GPS
  • Save config to chip (if possible):
# ubxtool -p SAVE
