Hello,
We are using A-GPS in our application to get faster TTFF and will be reading location coordinates after every 5 mins of duration. The application flow looks like:- Connect to LTE network through LwM2M carrier lib ------ Enable PSM mode, Activate GPS, get Long & Lat coordinates, Stop GPS, Disable PSM mode ------ Disconnect LTE modem. (Repeat same steps after 5 mins.).
Randomly, after 1 or 2 hours of long run nRF9160 will stuck at below mentioned logs:
GPS_EVT_AGPS_DATA_NEEDED [03:14:49.960,083] <dbg> nrf9160_gps.gps_priority_set: GPS priority disabled [03:14:49.960,296] <dbg> nrf9160_gps.start: GPS operational [03:14:49.960,388] <dbg> nrf9160_gps.gps_thread: A-GPS data update needed
But this time we could see our test is end up with SUPL error: 3

Can you please support me to solve this issues asap and explain us why and what exactly is happening when we are performing long running test ?
