I'm not 100%, but GDB may be responsible for interfering with the soft device function call triggering a reset. Without GDB it seems to work fine :(

I'm not sure what the name is, its just the default code.

err_code = ble_advertising_init(&advdata, &scanrsp, &options, on_adv_evt, NULL);

This returns 0

(gdb) p/x err_code $3 = 0x0

Can you show what m_adv_uuids is configured to, and what's the name of the device? You should check the return value of ble_advertising_init

Your softDevice is in Flash yes? and you've called ble_stack_init() before? Are you able to get an example like HRS working?

The function does not return, so there is no return value.

What is the value of err_code?
Can you post your complete advertising_init function?

I'm using the example code without edits.

The code resets/crashes here: err_code = sd_ble_gap_adv_start(&adv_params); Which is a soft device call

if (m_adv_mode_current != BLE_ADV_MODE_IDLE)
{
err_code = sd_ble_gap_adv_start(&adv_params); if(err_code != NRF_SUCCESS) {
return err_code; }
}

Can you provide the code where you set up the advertisement? The failure to start may be due to bad parameters. Also, the return code will be helpful.
