This is the demo for users to use ESP_APIs to create a GATT Client.
To test this demo, you can run the gatt_server_demo, which creates services and starts advertising. Gatt_client_demo will start scanning and connect to the gatt_server_demo automatically.
This demo will enable gatt server's notification function once the connection is established and then the devices start exchanging data.
Please check the tutorial for more information about this example.
