Android-BLE蓝牙框架,提供了扫描、连接、使能/除能通知、发送/读取数据、接收数据,读取rssi,设置mtu等蓝牙相关的所有操作接口,内部优化了连接队列,以及快速写入队列, 并支持多服务通讯,可扩展配置蓝牙相关操作。

Android-BLE API

  • Ble - 最重要的类,对外提供所有的蓝牙操作接口.
  • BleDevice - 封装了蓝牙对象类,包含蓝牙连接状态以及基本蓝牙信息.
  • BleLog - 内部日志类,开发环境下打开可查看蓝牙相关操作信息.
  • BleStates - 蓝牙操作异常状态码信息类.(扫描、连接、读写等异常状态码).
  • ByteUtils - 各种字节数据转换的工具类.
  • CrcUtils - 字节校验的crc各种算法的工具类.
  • UuidUtils - 蓝牙服务/特征uuid转换工具类.

异常状态码

BleStates

接入前提示

1. 如果项目中的设备是统一类型(服务,特征uuid相同),则推荐在初始化时把服务,特征的uuid配置完整。
2. 如果项目中需要兼容多种设备类型(服务,特征uuid不相同),则在通信时需要使用byUuid的方式进行。

接入文档

1. 在 build.gradle 中添加下面依赖. Download

implementation 'cn.com.superLei:blelibrary:latestVersion'

2. 在Application中初始化.

private void initBle() {
    Ble.options()//开启配置
        .setLogBleEnable(true)//设置是否输出打印蓝牙日志(非正式打包请设置为true,以便于调试)
        .setThrowBleException(true)//设置是否抛出蓝牙异常 (默认true)
        .setAutoConnect(false)//设置是否自动连接 (默认false)
        .setIgnoreRepeat(false)//设置是否过滤扫描到的设备(已扫描到的不会再次扫描)
        .setConnectTimeout(10 * 1000)//设置连接超时时长(默认10*1000 ms)
        .setMaxConnectNum(7)//最大连接数量
        .setScanPeriod(12 * 1000)//设置扫描时长(默认10*1000 ms)
        .setScanFilter(scanFilter)//设置扫描过滤
        .setUuidService(UUID.fromString(UuidUtils.uuid16To128("fd00")))//设置主服务的uuid(必填)
        .setUuidWriteCha(UUID.fromString(UuidUtils.uuid16To128("fd01")))//设置可写特征的uuid (必填,否则写入失败)
        .setUuidReadCha(UUID.fromString(UuidUtils.uuid16To128("fd02")))//设置可读特征的uuid (选填)
        .setUuidNotifyCha(UUID.fromString(UuidUtils.uuid16To128("fd03")))//设置可通知特征的uuid (选填,库中默认已匹配可通知特征的uuid)
        .setUuidServicesExtra(new UUID[]{BATTERY_SERVICE_UUID})//设置额外的其他服务组,如电量服务等
        .setFactory(new BleFactory() {//实现自定义BleDevice时必须设置
            @Override
            public MyDevice create(String address, String name) {
                return new MyDevice(address, name);//自定义BleDevice的子类
            }
        })
        .setBleWrapperCallback(new MyBleWrapperCallback())//设置全部蓝牙相关操作回调(例: OTA升级可以再这里实现,与项目其他功能逻辑完全解耦)
        .create(mApplication, new Ble.InitCallback() {
            @Override
            public void success() {
                BleLog.e("MainApplication", "初始化成功");
            }

            @Override
            public void failed(int failedCode) {
                BleLog.e("MainApplication", "初始化失败:" + failedCode);
            }
        });
     }

3. 开始使用.

1.扫描

ble.startScan(scanCallback);

扫描回调 (注: 记得打开蓝牙并检查是否授予蓝牙权限)

BleScanCallback<BleDevice> scanCallback = new BleScanCallback<BleDevice>() {
        @Override
        public void onLeScan(final BleDevice device, int rssi, byte[] scanRecord) {
            //Scanned devices
        }

       @Override
        public void onStart() {
            super.onStart();
        }

        @Override
        public void onStop() {
            super.onStop();
        }

        @Override
        public void onScanFailed(int errorCode) {
            super.onScanFailed(errorCode);
            Log.e(TAG, "onScanFailed: "+errorCode);
        }
    };

2.连接/断开

//连接设备
ble.connect(device, connectCallback);

//连接多个设备
ble.connects(devices, connectCallback);

//取消正在连接的设备
ble.cancelConnecting(device);

//取消正在连接的多个设备
ble.cancelConnectings(devices);

//断开设备
ble.disconnect(device);

//断开所有设备
ble.disconnectAll();

连接/断开回调

private BleConnCallback<BleDevice> connectCallback = new BleConnCallback<BleDevice>() {
        @Override
        public void onConnectionChanged(BleDevice device) {

        }

        @Override
        public void onConnectTimeOut(BleDevice device) {
            super.onConnectTimeOut(device);
            Log.e(TAG, "onConnectTimeOut: " + device.getBleAddress());
        }

        @Override
        public void onConnectCancel(BleDevice device) {
            super.onConnectCancel(device);
            Log.e(TAG, "onConnectCancel: " + device.getBleName());
        }

        @Override
        public void onServicesDiscovered(BleDevice device, BluetoothGatt gatt) {
            super.onServicesDiscovered(device, gatt);
        }

        @Override
        public void onReady(BleDevice device) {
            super.onReady(device);
            //connect successful to enable notification
            ble.enableNotify(...);
        }

        @Override
        public void onConnectException(BleDevice device, int errorCode) {
            super.onConnectException(device, errorCode);

        }
    };

3.使能/除能通知

ble.enableNotify(device, true, new BleNotifyCallback<BleDevice>() {
        @Override
        public void onChanged(BleDevice device, BluetoothGattCharacteristic characteristic) {
            UUID uuid = characteristic.getUuid();
            BleLog.e(TAG, "onChanged==uuid:" + uuid.toString());
            BleLog.e(TAG, "onChanged==data:" + ByteUtils.toHexString(characteristic.getValue()));
        }

        @Override
        public void onNotifySuccess(BleDevice device) {
            super.onNotifySuccess(device);
            BleLog.e(TAG, "onNotifySuccess: "+device.getBleName());
        }
    });

4.读取数据

ble.read(device, new BleReadCallback<BleRssiDevice>() {
            @Override
            public void onReadSuccess(BleRssiDevice dedvice, BluetoothGattCharacteristic characteristic) {
                super.onReadSuccess(dedvice, characteristic);
            }

            @Override
            public void onReadFailed(BleRssiDevice device, int failedCode) {
                super.onReadFailed(device, failedCode);
            }
        })

5.写入数据

//写入一包数据
ble.write(device, data, new BleWriteCallback<BleRssiDevice>() {
    @Override
    public void onWriteSuccess(BleRssiDevice device, BluetoothGattCharacteristic characteristic) {

    }

    @Override
    public void onWriteFailed(BleRssiDevice device, int failedCode) {
        super.onWriteFailed(device, failedCode);
    }
});

//写入大数据(文件、图片等)
byte[]data = toByteArray(getAssets().open("WhiteChristmas.bin"));
ble.writeEntity(mBle.getConnectedDevices().get(0), data, 20, 50, new BleWriteEntityCallback<BleDevice>() {
    @Override
    public void onWriteSuccess() {

    }

    @Override
    public void onWriteFailed() {

    }

    override void onWriteProgress(double progress) {

    }

    override void onWriteCancel() {

    }
});

//写入数据到队列中 (默认发送间隔50ms)
ble.writeQueue(RequestTask.newWriteTask(address, data));
//写入数据到队列中 (自定义间隔时间)
ble.writeQueueDelay(delay, RequestTask.newWriteTask(address, data));

//通过特定服务和特征值uuid写入数据
ble.writeByUuid(device, data, serviceUuid, charUuid, new BleWriteCallback<BleRssiDevice>() {
    @Override
    public void onWriteSuccess(BleRssiDevice device, BluetoothGattCharacteristic characteristic) {

    }

    @Override
    public void onWiteFailed(BleRssiDevice device, int failedCode) {
        super.onWiteFailed(device, failedCode);
    }
});

6. 移除监听(scan、connect)

ble.cancelCallback(connectCallback);
或
ble.cancelCallback(scanCallback);

8. 释放资源

 ble.released();
