  • Hi.

    • You cannot send anything to a device you are not connected to. You can however configure the peer device to do something when a disconnect event is detected. You can do the same for the connected event.
    • These event come in through the event handler of your application. I will assume that you are using the proximity example project. look inside the ble_evt_dispatch in main.c You see that many event handler for different services are called. If you look inside the link loss service event handler, ble_lls_on_ble_evt, you see that it will act on the BLE_GAP_EVT_DISCONNECTED event. It will report a link loss event to the application.
    • You can also handle the BLE_GAP_EVT_CONNECTED in any way you want to.
