Hello,

The NRF_SDH_BLE_OBSERVER macro is used to register application layer functions as observers to specific SoftDevice events. In essence, this means that events from the SoftDevice's different components will be sent to the application layer of your program.
You can read more in-depth about this in the SoftDevice Handler Library documentation. Specifically, you might be interested in the Registering with the nrf_sdh_* components section.

Best regards,
Karl
