I didn't have quite this much success. Did you get a fix using "device = NMEADevice"? No but I did find an explanation for the problem: http://git.freesmartphone.org/?p=framework.git;a=commitdiff;h=5271e445b327c2132eee6a1f43fcf58c37c67e00 I applied the patch manually and things seem to be working now.

Hi, Quoting Jonathan Schultz : ... so moving the pickle file out of the way ... rm /var/lib/freesmartphone/ogpsd.pickle ... restoring /etc/frameworkd.conf ... [ogpsd] device = GTA02Device ... going outside ... and theres a fix within 60 seconds! I didn't have quite this much success. Did you get a fix using "device = NMEADevice"? Just an idea, Erich ___ Smartphones-userland mailing list Smartphones-userland@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/smartphones-userland

... so moving the pickle file out of the way ... rm /var/lib/freesmartphone/ogpsd.pickle ... restoring /etc/frameworkd.conf ... [ogpsd] device = GTA02Device ... going outside ... and theres a fix within 60 seconds! I didn't have quite this much success. The GPS did go back to sending UBX data, which is good, but after some time (10 mins?) it still had no fix, though it had got the time so maybe it was just being slow at getting a fix). I turned the GPS off then on again, and it was back to sending NMEA data. So I had to delete the pickle file again, and apparently the same each time I turn off the GPS. Also, although I can see the time in the UBX data, requesting the time through dbus doesn't work. Likewise fso-gpsd doesn't appear to receive any data. So it looks like some other problem in ogpsd? I'd take a look if I knew where to start. I know there's no hardware problem because the GPS works fine with other distros.

My guess is you'll see the GPS crash and restart. This used to be a problem when loading bad almanac and/or ephemeris data, but I thought that was fixed long ago.

Yes the gps returns NMEA data when you turn it on. Tell it to switch to UBX mode (I don't know how). > 4. what exactly is introducing the change? Hard to say since I don't have your system here.
