Testing the nrf_modem_fault_handler

[Niklas Norin]

We have experienced some modem faults and have implemented a custom `nrf_modem_fault_handler` to try to capture them.

We have enabled the config:

CONFIG_NRF_MODEM_LIB_ON_FAULT_APPLICATION_SPECIFIC=y
CONFIG_NRF_MODEM_LIB_FAULT_STRERROR=y

Do you have any recommendation on how to test that the modem will indeed call our `nrf_modem_fault_handler`?

E.g. a modem interaction that is sure to fault would be helpful.

Thank you in advance!

Hello,

E.g. a modem interaction that is sure to fault would be helpful.

have you tried searching the devzone for ways to cause modem crash? There are plenty of cases with instructions for how to reproduce various modem fault behavior.
