So it asserts in the next step after line 230? Are you using the Softdevice? Note that there is a specific debug procedure for debugging with Softdevice.

okay, I need to take back the posts.
The code is actually not getting stuck in the soft device functions, It's getting stuck in nrf_drv_init().

I thought it was getting stuck on advertising, but then I added a breakpoint to the serial function. When I comment out the serial function, the code works fine.

The problem is, that I still cannot tell which function it's getting stuck at because the call stack is empty.

Please help,

thanks

You mean in:

    if (p_advertising->evt_handler != NULL)
    {
        p_advertising->evt_handler(p_advertising->adv_evt);
    }

What does p_advertising->evt_handler point at?

I'm using Soft device "s140_nrf52_6.0.0_softdevice.hex".

I tried debugging, it seems to be getting stuck at :

Edit: It actually gets stuck in the if statement on line 663 event handler

Hi,

Are you using a Softdevice? You can use breakpoints to see how far the application reach before it asserts. See our guide on debugging in SES here.
