Re: [Discuss-gnuradio] get GPS time from GPSDO module

[Bastien Auneau]

I use :

uhd::sensor_value_t val = usrp->get_mboard_sensor("gps_time");

std::cout << val.to_pp_string() << std::endl;

I got first an unhandled exception runtime error

at second run, it outputs :

GPS time: 2077252342 seconds

and these two in a row at each try

Also, the value returned 2077252342 never increase

And I did not plug the GPS antenna, so the GPSDO is not locked

How can I get is stable ?

Why runtime error pops up half of the time ?

should I plug the antenna and wait for GPS lock ?

How do I check if GPS is locked ?

The mboard_sensors interface should be used.
get_mboard_sensor("gps_time") should get you what you're looking for.
