Using the packet_forwarder, I got these kind of errors, preventing me to activate beacons and I think to have better packet timestamping accuracy:

As you can see, GPS position is updated, but still, I have an invalid GPS time reference. Output from "date -R" on my system returns the correct time and date.

Hi, did you manage to solve the problem ?

kersing commented 5 years ago

There have been extensive discussions regarding GPS on the TTN forum resolving some issues. Are you still having issues or are your issues resolved?

kersing commented 5 years ago

I will close this issue as resolved in 10 days if no feedback is provided.

Asghar-Usman commented 5 years ago

I could not resolve the issue, but as i am no more using the TTN network you can close the thread.
