Revision as of 01:13, 7 June 2007

The Neo1973 device contains an integrated GPS. The particular device is marketed as an AGPS, and there is some discussion available as to what significance that "A" might have.

As of P1, a binary-only program for talking the the GPS is available in /home/root/DM2/gps, (and presumably, the same binary would function on a P0 device). There is an ongoing effort to write a Free Software program that could be used instead of this binary-only program. See Hammerhead_protocol for details and the latest status.

In the meantime, Pavel Machek provides the following script for recording an NMEA stream from the binary program:

#!/bin/sh
echo 1 > /sys/class/leds/gta01\:vibrator/brightness
killall gllin cat
sleep 1
echo 0 > /sys/class/leds/gta01\:vibrator/brightness
mknod /tmp/nmeaNP p
cat /tmp/nmeaNP | tee /media/card/gps.nmea >> /tmp/gps.nmea &
/home/root/DM2/gps/gllin -low 5
strace /home/root/DM2/gps/gllin >> /tmp/gps.strace 2>&1

He also succeeded at getting the Neo1973 to act like a bluetooth GPS with the following script:

#!/bin/sh
mknod /dev/rfcomm0 c 216 0
echo 1 > /sys/devices/platform/s3c2410-i2c/i2c-0/0-0008/gta01-pm-bt.0/power_on
sleep 1
hciconfig hci0 up name linuxgps
sleep 1
sdpd
sleep 1
sdptool add SP
(
	while true; do
	rfcomm listen /dev/rfcomm0 1
	sleep 1
	done
) &
(
	while true; do
	tail -f /tmp/gps.nmea > /dev/rfcomm0
	sleep 1
	done
) &

As people develop more sophisticated GPS applications, please note them here.

Here are some ideas for possibilites:

  • Cairo-based mapping
  • Routing
  • Openstreetmap logger, (with voice annotations)

The Neo1973 device contains an integrated GPS. The particular device is marketed as an AGPS, and there is some discussion available as to what significance that "A" might have.

As of P1, a binary-only program for talking the the GPS is available in /home/root/DM2/gps, (and presumably, the same binary would function on a P0 device). There is an ongoing effort to write a Free Software program that could be used instead of this binary-only program. See Hammerhead_protocol for details and the latest status.

In the meantime, Pavel Machek provides the following script for recording an NMEA stream:
