gps values delayed

[Ralph Nemitz]

Hallo together,

I' using an ublox NEO-M8P-2-11 and gpsd-3.19 go get the position.

If I start gpsd, no signals occur (nmea_0.log). After a while the time 
comes (nmea_1.log). Later also latitude and longitude have the right 
values (nmea_2.log).

If I kill gpsd and start it new wrong values for latitude and longitude 
occur (nmea_3.log, nmea_4.log).

The gpsd wall called by "gpsd -n /dev/ttyACM1".

The logfile I got by "gpspipe -r -n 50 > nmea_*.log".

It can also happen that the values come right directly after switching 
on the board, after 30 min or 3 hours.

I think there is hardware problem but not sure.

Do you have any experience with such a strange behavior? Is there a 
possibility the get more information (output with debug brought nothing)?

Any help is appreciated!

Regards

Ralph
