*
* This demo showcases creating a GATT database using a predefined attribute table.
* It acts as a GATT server and can send adv data, be connected by client.
* Run the gatt_client demo, the client demo will automatically connect to the gatt_server_service_table demo.
* Client demo will enable GATT server's notify after connection. The two devices will then exchange
* data.
