Every once in a while I will get a failure that results in the app_error_fault_hanlder() being called and the following info:
ID = 1
PC = 0x14550
error_code = 0x495
line_num = 0x400.
I used the nrf_strerror_get() to try to figure out, but it just returns "Unknown error code".
It happens infrequently, maybe a couple of times per day. Can you provide some info on this error?
