Server¶

Now, an Android server can be built to implement Bluetooth communication between two Androids. (Currently only supports single device connection)

Build instance¶

val serialPortServer = SerialPortServerBuilder
            .setServerName("SerialPortServer")
            .setServerUUID("00001101-0000-1000-8000-00805F9B34FB")
            .setServerReceivedDataCallback {
                
            }
            .setServerConnectStatusCallback { status, bluetoothDevice ->
                
            }
            .build(this)

setServerName Set server name
setServerUUID Set the UUID of the server, the UUID of the traditional device needs to be set to the same as this when the client connects
setServerReceivedDataCallback The server receives message monitoring
setServerConnectStatusCallback Server connection status monitoring
- status Connection Status
- bluetoothDevice Connected device, null when status is false

Open server¶

Only after the service is opened, the client can connect to the server.

serialPortServer.openServer()

Close server¶

serialPortServer.closeServer()

Set the server discoverable state¶

By default, if the server is turned on, it will be automatically set to be discoverable, and if the server is turned off, it will be set to be invisible.

setServerDiscoverable(status)

status is of type Boolean, indicating the discoverable status

Disconnect¶

Actively disconnect from the client

serialPortServer.disconnect()

Send¶

serialPortServer.sendData("Hello")
