What exactly are you looking for? Take a look at this question for an explanation of the different roles in BLE.

If you need a GATT Client as a Peripheral, you can take a look at for example ble_ias_c.c in Source\ble\ble_services, and see how it's used in ble_app_proximity. If you need a GATT Client as a Central you can look at ble_app_hrs_c in Board\nrf6310\s120\experimental\ble_app_hrs_c.
