how do I disable automatic advertising after BLE_GAP_EVT_DISCONNECT?

[Richard von Lehe]

I want as much control over advertising as possible. Barring that, I want to understand why the softdevice automatically goes back into advertising after a GAP disconnect event.

Why does the device automatically advertise when a disconnect event occurs? I can see that this might often be beneficial, but I would also imagine there must be a way to disable this functionality.

Rather than change ble_advertising, I decided to make sure the ble_advertising_on_ble_evt is called before on_ble_evt in my main. Then in this application event handler, I go ahead and immediately disable advertising using sd_ble_gap_advertising_stop. It's ugly, but this is for a demo and it seems better than hacking the SDK-level code which would affect all applications.
