A Flutter plugin to expose the features of Bluetooth Adapter for Android only.
The primary purpose of this project was to communicate between flutter and Rasburry Pie using Bluetooth.
- Setting up a UUID from user end.
- Checking Bluetooth connection status and giving alerts if its off or not right.
- Getting list of paired devices.
- Get a particular paired device info.
- Start Bluetooth server.
- Start Bluetooth client.
- Start Bluetooth client.
- Send message to a connected device.
- Stream for listening to received messages.
- Stream for listening to connection status (CONNECTED, CONNECTING, CONNECTION FAILED, LISTENING, DISCONNECTED).
For a full example please check /example folder. Here are only the most important parts of the code to illustrate how to use the library.
//Initiatinng the bluetooth adapter
Bluetoothadapter flutterbluetoothadapter = Bluetoothadapter();
//Listening to the connection status listener
String _connectionStatus = "NONE";
StreamSubscription _btConnectionStatusListener =flutterbluetoothadapter.connectionStatus().listen((dynamic status) {
setState(() {
_connectionStatus = status.toString();
});
});
//Listening to the recieved messages
String _recievedMessage;
StreamSubscription _btReceivedMessageListener = flutterbluetoothadapter.receiveMessages().listen((dynamic newMessage) {
setState(() {
_recievedMessage = newMessage.toString();
});
});
List<BtDevice> devices = await flutterbluetoothadapter.getDevices();
await flutterbluetoothadapter.getDevice(deviceAddress);
await flutterbluetoothadapter.startServer();
flutterbluetoothadapter.startClient(devices.indexOf(element), true);
flutterbluetoothadapter.sendMessage(messageString);
await flutterbluetoothadapter.checkBluetooth(); //returns bool
flutterbluetoothadapter.initBlutoothConnection(uuid);
