app_error_fault_handler() called with PC at 0x172C0 (dec. 94912)

Hi,

I am developping on a nRF52DK board with the PCA10040 and reference nRF52823 using the SDK 16.0.0 and the nrf5 SDK for Mesh v4.0.0 and have successfully been able to realise an application that can send messages between several boards in a mesh network, using the light_switch example as a starting point.

I now have to merge it with several drivers developped by the company I work for (the drivers allow for example to use an API to control the GPIO which acts as an interface between the code and the SDK). However I am running into some troubles as when running the program, after a few seconds it faults and enter the app_error_fault_handler() function.

After some debugging and some more researches, I discovered that it is related to an Assert problem within the softdevice as I have the following parameters when entering the app_error_fault_handler function :

I have seen some similar posts while browsing though the forum, but none of them had the same adress as I have.

Do you have any idea what could be causing the problem ?

Thanks in advance, regards

Quentin

Hi.

It's almost impossible for me to know what causing the assert here. You will need to either debug your code and find exactly which part of your code is causing the assert.

Or you can use addr2line to find what part of the code match the address.

Thanks for your quick reply, in the end it turned out that the Softdevice was crashing because I was debugging my application, everything works fine when it runs normally.
