    BluetoothLE-Multi-Library

    一个能够连接多台蓝牙设备的库,它可以作为client端,也可以为server端。支持主机/从机,外围设备连接。
    在发送消息时,它内部支持队列控制,避免因蓝牙间隔出现操作失败的情况。

    开始使用

    1. 主机client

    扫描

    BluetoothLeScannerCompat scannerCompat = BluetoothLeScannerCompat.getScanner();
    ScanSettings scanSettings = new ScanSettings.Builder()
        .setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY)
        .setReportDelay(int reportDelayMillis) //0 or above >0
        .setUseHardwareBatchingIfSupported(false)
        .build();
        
    //设置过滤扫描
    List<ScanFilter> filters = new ArrayList<>();
    
    ScanFilter builder = new ScanFilter.Builder().setDeviceName(deviceName).build();
    filters.add(builder);
    
    ScanFilter builder = new ScanFilter.Builder().setDeviceAddress(deviceAddress).build();
    filters.add(builder);
    
    ScanFilter builder = new ScanFilter.Builder()
                        .setServiceUuid(ParcelUuid.fromString(serviceUUID.toString())).build();
    filters.add(builder);
    
    scannerCompat.startScan(filters, scanSettings, scanCallback);
    

    扫描回调

    private ScanCallback scanCallback = new ScanCallback() {
            @Override
            public void onScanResult(final int callbackType, final ScanResult result) {
    
            }
    
            @Override
            public void onBatchScanResults(final List<ScanResult> results) {
    
            }
    
            @Override
            public void onScanFailed(final int errorCode) {
    
            }
    };

    连接

    //创建连接的一个对象,后续将使用该对象来访问操作
    private BluetoothLeConnector connector = BluetoothLe.newConnector();
    private BluetoothGatt mBluetoothGatt;
    
            //配置连接对象
            connector.setConfig(new BluetoothConfig.Builder()
                    .enableQueueInterval(true)//开启操作时间间隔
                    .setQueueIntervalTime(BluetoothConfig.AUTO)//单位ms,这里为自动
                    .build());
            //连接蓝牙
            connector.connect(true, mBluetoothDevice);
            connector.connect(true, mBluetoothDevice, BluetoothLeConnector.TRANSPORT_AUTO);//最后一个参数设置连接通道
            //开启indicate通知
            connector.enableIndication(true,UUID_SERVICE,UUID_INDICATION);
            //开启notify通知
            connector.enableNotification(true, UUID_SERVICE, UUID_NOTIFICATION);
            //写数据
            connector.writeCharacteristic(new byte[]{0x01, 0x02}, UUID_SERVICE, UUID_WRITE);
            //自定义写数据
            BluetoothGattService service = mBluetoothGatt.getService(UUID_SERVICE);
            BluetoothGattCharacteristic characteristic = service.getCharacteristic(UUID_WRITE);
            characteristic.setValue(byte[] value);
            characteristic.setValue(int value, int formatType, int offset);
            characteristic.setValue(int mantissa, int exponent, int formatType, int offset);
            characteristic.setValue(String value);
            connector.writeCharacteristic(characteristic);
            //读数据
            connector.readCharacteristic(UUID_SERVICE, UUID_READ);
            //断开连接
            connector.disconnect();
            //关闭gatt
            connector.close();
    

    回调监听

    //连接状态监听
    private ConnectListener mConnectListener = new ConnectListener() {
        @Override
        public void connecting() {
    
        }
    
        @Override
        public void connected() {
    
        }
    
        @Override
        public void disconnected() {
    
        }
    
        @Override
        public void onServicesDiscovered(BluetoothGatt gatt, int status) {
    
        }
    
        @Override
        public void error(ConnBleException e) {
    
        }
    };
    connector.addConnectListener(mConnectListener);

    更多的回调监听如下:

    mBleManager.addConnectListener(...)
    mBleManager.addNotificationListener(...)
    mBleManager.addIndicationListener(...)
    mBleManager.addWriteCharacteristicListener(...)
    mBleManager.addReadCharacteristicListener(...)
    mBleManager.addRssiListener(...)

    移除回调监听(好的程序员要懂避免内存泄漏):

    connector.removeListener(mConnectListener);

    2. 从机Server

    广播

    private GattServer mGattServer = new GattServer();
    
    mGattServer.startAdvertising(UUID.fromString("0000fff0-0000-1000-8000-00805f9b34fb"));//该uuid可提供给主机client过滤扫描
    
    mGattServer.stopAdvertising();

    伺服器server

    1. 启动startServer
    mGattServer.startServer(context);
    2. 关闭closeServer
    mGattServer.closeServer();
    3. 添加服务addService
    List<ServiceProfile> list = new ArrayList<>();
    
    //设置一个写的特征
    ServiceProfile profile = new ServiceProfile();
    profile.setCharacteristicUuid(UUID.fromString("0000fff3-0000-1000-8000-00805f9b34fb"));
    profile.setCharacteristicProperties(BluetoothGattCharacteristic.PROPERTY_WRITE);
    profile.setCharacteristicPermission(BluetoothGattCharacteristic.PERMISSION_WRITE);
    profile.setDescriptorUuid(GattServer.CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR_UUID);
    profile.setDescriptorPermission(BluetoothGattDescriptor.PERMISSION_READ);
    profile.setDescriptorValue(new byte[]{0});
    list.add(profile);
    
    //设置一个读的特征
    ServiceProfile profile1 = new ServiceProfile();
    profile1.setCharacteristicUuid(UUID.fromString("0000fff2-0000-1000-8000-00805f9b34fb"));
    profile1.setCharacteristicProperties(BluetoothGattCharacteristic.PROPERTY_READ);
    profile1.setCharacteristicPermission(BluetoothGattCharacteristic.PERMISSION_READ);
    profile1.setDescriptorUuid(GattServer.CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR_UUID);
    profile1.setDescriptorPermission(BluetoothGattDescriptor.PERMISSION_READ);
    profile1.setDescriptorValue(new byte[]{1});
    list.add(profile1);
    
    //设置一个notify通知
    ServiceProfile profile2 = new ServiceProfile();
    profile2.setCharacteristicUuid(UUID.fromString("0000fff1-0000-1000-8000-00805f9b34fb"));
    profile2.setCharacteristicProperties(BluetoothGattCharacteristic.PROPERTY_NOTIFY);
    profile2.setCharacteristicPermission(BluetoothGattCharacteristic.PERMISSION_READ);
    profile2.setDescriptorUuid(GattServer.CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR_UUID);
    profile2.setDescriptorPermission(BluetoothGattDescriptor.PERMISSION_WRITE);
    profile2.setDescriptorValue(new byte[]{1});
    list.add(profile2);
    
    final ServiceSettings serviceSettings = new ServiceSettings.Builder()
            .setServiceUuid(UUID.fromString("0000fff0-0000-1000-8000-00805f9b34fb"))//服务uuid
            .setServiceType(BluetoothGattService.SERVICE_TYPE_PRIMARY)
            .addServiceProfiles(list)//上述设置添加到该服务里
            .build();
    
    mGattServer.addService(serviceSettings);

    回调监听

            mGattServer.setOnAdvertiseListener(new OnAdvertiseListener() {
                @Override
                public void onStartSuccess(AdvertiseSettings settingsInEffect) {
                    setContentText("开启广播  成功,uuid:0000fff0-0000-1000-8000-00805f9b34fb");
                }
    
                @Override
                public void onStartFailure(int errorCode) {
                    setContentText("开启广播  失败,uuid:0000fff0-0000-1000-8000-00805f9b34fb");
                }
    
                @Override
                public void onStopAdvertising() {
                    setContentText("停止广播,uuid:0000fff0-0000-1000-8000-00805f9b34fb");
                }
            });
    
            mGattServer.setOnServiceAddedListener(new OnServiceAddedListener() {
                @Override
                public void onSuccess(BluetoothGattService service) {
                    setContentText("添加服务成功!");
                }
    
                @Override
                public void onFail(BluetoothGattService service) {
                    setContentText("添加服务失败");
                }
            });
    
            mGattServer.setOnConnectionStateChangeListener(new OnConnectionStateChangeListener() {
                @Override
                public void onChange(BluetoothDevice device, int status, int newState) {
    
                }
    
                @Override
                public void onConnected(BluetoothDevice device) {
                    setContentText("连接上一台设备 :{ name = " + device.getName() + ", address = " + device.getAddress() + "}");
                    mBluetoothDevice = device;
                }
    
                @Override
                public void onDisconnected(BluetoothDevice device) {
                    setContentText("设备断开连接 :{ name = " + device.getName() + ", address = " + device.getAddress() + "}");
                }
            });
    
            mGattServer.setOnWriteRequestListener(new OnWriteRequestListener() {
                @Override
                public void onCharacteristicWritten(BluetoothDevice device, BluetoothGattCharacteristic characteristic, byte[] value) {
                    setContentText("设备写入特征请求 : device = " + device.getAddress() + ", characteristic uuid = " + characteristic.getUuid().toString() + ", value = " + Arrays.toString(value));
                }
    
                @Override
                public void onDescriptorWritten(BluetoothDevice device, BluetoothGattDescriptor descriptor, byte[] value) {
                    setContentText("设备写入描述请求 : device = " + device.getAddress() + ", descriptor uuid = " + descriptor.getUuid().toString() + ", value = " + Arrays.toString(value));
                }
            });
