Hi Joel,

I have modified the code using

err_code = sd_ble_gap_adv_stop(m_advertising.adv_handle);

and it looked as if this has worked well.

Note that the function will return 'invalid state' if the stack is not advertising at that point. You may want to ignore that error.

Yes, you the stack will not draw any additional current if you stop any ongoing BLE activities such as active connections, advertising, or scanning.

Hi Joel,

sd_ble_gap_adv_stop() expects the advertisment handle (uint8_t) as input, not the advertisment struct you are passing to the function. Since the Softdevice only supports one advertisment handle, you can hardcode it to '0'.

(void) sd_ble_gap_adv_stop(0);
