HEllo,

I suggest to for instance look at the usage of the advertising module in the ble_app_hrs example.

You typically init the module by calling ble_advertising_init() with the durations of advertisment you want to perform, and start advertisement by calling ble_advertising_start(). As the advertisement is switching modes you will get events in the on_adv_evt() callback handler. For instance when all advertisement modes have occured it will go to idle as reported by an BLE_ADV_EVT_IDLE event in on_adv_evt(). 

You can at any time call ble_advertising_start() to switch advertising mode or even go directly to idle by calling ble_advertising_start(&m_advertising, BLE_ADV_MODE_IDLE).
