softdevice_fault_handler called when single stepping

[daveb1]

When I'm single stepping my nRF52 application in Keil with a BLE connection I always get the softdevice_fault_handler called.

I'm using SD 132, v2.0.0 and the the parameters passed to softdevice_fault_handler are: id = 1, pc = variable (always in SD address space), info = 0

Any idea what fault_id 1 is and where other ids are documented ?

Thanks Dave

Hi

as soon as the soft device is running, you can't single step due to the BLE time slots. You could use RTT logging for debugging purposes.

In all other cases you will run into the fault handler.

Thanks for the answer. It looks like ETM trace might be useful here
