Hello,
I am having an issue with the GPS on the nRF9160. I have been developing a custom program that will switch between NB-IoT and GPS when an interrupt pin is triggered. This code has all been tested in isolation and modulised into various source code files.
When the modules are brought together, the code works but only for a while. Eventually the code will hard fault when switching to GPS mode. To be clear, it is not the act of calling the GPS socket set-up but after the socket is initialised and the first 'scanning' line is printed. The hard fault can occur at the very first activation of the GPS, or the second, or the third, etc. it is not specific to any one call of the GPS module.
I have noticed that in the sample GPS program, there is a k_sleep() function placed in the main while loop that controls the scan frequency of the GPS. When this function is manipulated to increase the amount of milliseconds waited between cycles, the device will hardfault immediately after the GPS is initialised. This is leading me to believe my issue lies with this aspect of the GPS code.
From my own tests in my code, manipulating k_sleep(); has lead to more GPS cycles being completed before a hard fault occurs in the device.
For 3 tests across each k_sleep(), 1 full cycle is NB-IoT -> GPS -> NB-IoT without fault
At k_sleep() set to 50 milliseconds: cycles complete 4/6/6 before fault
At k_sleep() set to 100 milliseconds: cycles complete 6/1/6 before fault
At k_sleep() set to 250 milliseconds: cycles complete 3/6/2 before fault
At k_sleep() set to 500 milliseconds: cycles complete 2/3/1 before fault
At k_sleep() set to 750 milliseconds: cycles complete 1/2/2 before fault
At k_sleep() set to 900 milliseconds: cycles complete 3/1/1 before fault
At k_sleep() set to 1000 milliseconds: cycles complete 0/0/0 before fault
Note: Never could seem to get past 6 cycles before a fault (tried 50 milliseconds 10 times and 6 was the highest I could get to), may be a different issue or just bad luck but main issue here isn't related to the number of cycles the code does.
I am not able to show my current code publicly but the k_sleep(); I am referring to can be found on line 302 of the main gps sample code, manipulating that will cause my code to fault faster or slower. github.com/.../main.c
Terminal output for k_sleep() at 500millseconds:

What is the purpose behind the k_sleep() function and is there a way to avoid this issue?
EDIT:
Just to demonstrate the GPS code is functioning as expected before the fault and is capable of acquiring locks (including faster locks after the first cycle) after each interrupt trigger.
