Re: [gpsd-users] UBX-TIM-TP on F9T?

the latest from gitlab (3.19-661) does build OK for me.
I will try to look for the PPS message with an F9T later today and report what I find..

I tried, but could not get a PPS-message from gpsd.
Using u-center (which runs on wine) I do see the qErr value, and u-center can plot a graph of it over time which shows a saw-tooth from -4ns to +4ns, as expected.
ubxtool does show the UBX-TIM-TP message OK.

the output from my python client is below.
This might be tied to having a separate pps-device (?), but I don't have (or need) a separate /dev/pps0 device, I would just want to log the qErr value.
In time-transfer, the electrical PPS output from the receiver is used for other things.

cheers,
Anders
