Doesn't ble_scan_stop() return a status code?

It sounds like the nRF is entering the HardFault handler.

You should use the hardfault handler from the hardfault handling library. Just add the following files to your build and enable the handler in sdk_config.h:

- nRF5_SDK_15.3.0_59ac345\components\libraries\hardfault\hardfault_implementation.c

- nRF5_SDK_15.3.0_59ac345\components\libraries\hardfault\nrf52\handler\hardfault_handler_<name of toolchain used>.c

This handler will attempt to determine the cause and print out the error information.

I have a similar issue, related code as follow:
The scan had been stopped, but if I call ble_scan_stop() again after some while, it crashes atfer printing "Scan stop!" with no reason, and the call stack window show nothing, the dissassembly window show it crashed at :
4B01 ldr r3, [pc, #4]

source code:

void ble_scan_stop(void)
{
    nrf_ble_scan_stop();
    event_send(CENTRAL_SCAN_STOP, NULL);
    
    NRF_LOG_INFO("Scan stop!");
}

source code:

void ble_scan_stop(void)
{
    nrf_ble_scan_stop();
    event_send(CENTRAL_SCAN_STOP, NULL);
    
    NRF_LOG_INFO("Scan stop!");
}

Hi Asantos,

You need to provide more information, the content of the CPU registers, the call stack etc.

Are you stepping through the code after the SoftDevice has been enabled? Are you stepping into a function with a sd_-prefix, i.e. a SoftDevice function?

Best regards
