|
|
* This demo showcases BLE GATT server. It can send adv data, be connected by client.
|
|
* Run the gatt_client demo, the client demo will automatically connect to the gatt_server demo.
|
|
* Client demo will enable gatt_server's notify after connection. The two devices will then exchange
|
|
* data.
