I just found this text about nRF9160 connection loss.
nRF9160 uses the same radio for GPS and LTE connectivity. GPS signal is
caught between LTE transmissions and in case GPS "cold" fix acquisition takes
too much time, Anjay turns off LTE transmissions for the time of fix acquisition.
It can be seen by the following warning:
gps_nrf: GPS was interrupted multiple times by the LTE modem when producing a fix
.
Anjay is notified by it, enters offline mode and reconnects when the first fix is acquired and LTE is enabled back.
This was also added to the Thingy:91
documentation as they use the same baseband.

Hi,
As mentioned by the NRF documentation - this is intended behaviour to allow GPS to catch fix.
You can also disable GPS completely through KConfig options during compilation, or set timeout and cooldown values during runtime to different values

Yes, I know, and my point of #4 was exactly that. Add this functionality to the client so you don't need to recompile the entire client, just to turn on/off the GPS etc.
