Hi, unfortunately I still get no GPS data. I went for a 25 minute trip on a plain field, so GPS reception should be no prob. . When connecting via 'nc' to the gpsd I get output " GPSD,R=1 $GPRMC,,V,,,,,,,,,,N*53 $GPVTG,,,,,,,,,N*30 $GPGGA,,,,,,0,00,99.99,,,,,,*48 $GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30 $GPGSV,1,1,00*79 $GPGLL,,,,,,V,N*64 $GPZDA,,,,,00,00*48 $GPRMC,,V,,,,,,,,,,N*53 $GPVTG,,,,,,,,,N*30 $GPGGA,,,,,,0,00,99.99,,,,,,*48 $GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30 $GPGSV,1,1,00*79 $GPGLL,,,,,,V,N*64 $GPZDA,,,,,00,00*48 $GPRMC,,V,,,,,,,,,,N*53 $GPVTG,,,,,,,,,N*30 $GPGGA,,,,,,0,00,99.99,,,,,,*48 $GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30 $GPGSV,1,1,00*79 $GPGLL,,,,,,V,N*64 $GPZDA,,,,,00,00*48 $GPRMC,,V,,,,,,,,,,N*53 $GPVTG,,,,,,,,,N*30 $GPGGA,,,,,,0,00,99.99,,,,,,*48 $GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30 $GPGSV,1,1,00*79 $GPGLL,,,,,,V,N*64 $GPZDA,,,,,00,00*48 $GPRMC,,V,,,,,,,,,,N*53 $GPVTG,,,,,,,,,N*30 $GPGGA,,,,,,0,00,99.99,,,,,,*48 $GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30 ... " but when I use TangoGPS I don't see any positioning-data. Track-logging in tangoGPS only produced empty logfiles.
I have no external GPS antenna available at the moment. I read some posts after problems with the internal antenna, but I don't think that's the problem here.
