Android BLE 蓝牙开发框架，使用回调方式处理，搜索、连接、notify、indicate、读、写等一系列蓝牙操作。传参，然后回调结果，就是这么简单。

Usage

• 初始化

  bleManager = BleManager.getInstance();
  
  bleManager.init(this);
  

• 扫描指定名称设备、并连接

  bleManager.connectDevice(
          DEVICE_NAME,
          TIME_OUT,
          new BleManagerConnectCallback() {
              @Override
              public void onConnectSuccess(BluetoothGatt gatt, int status) {
                  Log.i(TAG, "连接成功！");
              }
  
              @Override
              public void onServicesDiscovered(BluetoothGatt gatt, int status) {
                  Log.i(TAG, "服务被发现！");
              }
  
              @Override
              public void onConnectFailure(BleException exception) {
                  Log.i(TAG, "连接失败或连接中断：" + '\n' + exception.toString());
              }
          });
  

• notify

  bleManager.notifyDevice(
          UUID_SERVICE_LISTEN,
          UUID_LISTEN_NOTIFY,
          UUID_CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR,
          new BleManagerNotifyCallback() {
              @Override
              public void onNotifyDataChangeSuccess(BluetoothGattCharacteristic characteristic) {
                  Log.d(TAG, "特征值Notification通知数据回调： "
                          + '\n' + Arrays.toString(characteristic.getValue())
                          + '\n' + HexUtil.encodeHexStr(characteristic.getValue()));
              }
  
              @Override
              public void onNotifyDataChangeFailure(BleException exception) {
                   Log.e(TAG, "特征值Notification通知回调失败: " + '\n' + exception.toString());
              }
  
          });
  

• indicate

  bleManager.indicateDevice(
          UUID_SERVICE_LISTEN,
          UUID_LISTEN_INDICATE,
          UUID_CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR,
          new BleManagerIndicateCallback() {
              @Override
              public void onIndicateDataChangeSuccess(BluetoothGattCharacteristic characteristic) {
                  Log.d(TAG, "特征值Indication通知数据回调： "
                          + '\n' + Arrays.toString(characteristic.getValue())
                          + '\n' + HexUtil.encodeHexStr(characteristic.getValue()));
              }
  
              @Override
              public void onIndicateDataChangeFailure(BleException exception) {
                  Log.e(TAG, "特征值Indication通知回调失败: " + '\n' + exception.toString());
              }
          });
  

• 写指令

  bleManager.writeDevice(
          UUID_SERVICE_OPERATE,
          UUID_OPERATE_WRITE,
          UUID_CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR,
          HexUtil.hexStringToBytes(SAMPLE_WRITE_DATA),
          new BleManagerWriteCallback() {
             @Override
             public void onDataWriteSuccess(BluetoothGattCharacteristic characteristic) {
                  Log.d(TAG, "写特征值成功: "
                          + '\n' + Arrays.toString(characteristic.getValue())
                          + '\n' + HexUtil.encodeHexStr(characteristic.getValue()));
             }
  
             @Override
             public void onDataWriteFailure(BleException exception) {
                  Log.e(TAG, "写读特征值失败: " + '\n' + exception.toString());
             }
          });
  

• 关闭操作

  bleManager.closeBluetoothGatt();
  

• 其他

  其他蓝牙操作可参考示例代码，或从BleManager这个类中开放的方法中找到。
