## Detailed Description

Definitions and prototypes for the GUS interface.

The Goodix UART Service is a customized GATT-based service with Tx, Rx and Flow Control characteristics. The application uses the service to send and receive data to and from the peer. The application data is sent to the peer as Handle Value Notification, and the data received from the peer is transmitted with GATT Write Command.

After gus_init_t variable is initialized , the application must call gus_service_init() to add the Goodix Uart Service and Rx, Tx, Flow Control characteristics to the BLE Stack database. The application can send the data to the peer with gus_tx_data_send() after GUS_EVT_TX_PORT_OPENED received. The application should copy the received data to its own buffer when handling GUS_EVT_RX_DATA_RECEIVED.
