It is registered using NRF_SDH_BLE_OBSERVER from ble_advertising.h. This is done using section variables, so it might look a bit like magic if you are not used to using it.

When is it being configured? I set the breakpoint in ble_advertising_on_ble_evt () and it comes over there on disconnect event. But I could not find any instance in the entire solution where it is being configured to handle this event.

Hi,

The ble_template project in SDK 16 uses the advertising module, and that will restart advertising when disconnected. You can see the implementation of this in <SDK>/components/ble/ble_advertising/ble_advertising.c. Upon a BLE_GAP_EVT_DISCONNECTED event, on_disconnected() is called, and that calls ble_advertising_start().

Hi,

you can search BLE_GAP_EVT_DISCONNECTED with entire project.

Then you can find that in ble_advertising.c line 116, it will advertising again.
