安装教程

1.在项目根目录下的build.gradle文件中，

allprojects {
   repositories {
       maven {
           url 'https://s01.oss.sonatype.org/content/repositories/releases/'
       }
   }
}

2.在entry模块的build.gradle文件中，

dependencies {
   implementation('com.gitee.chinasoft_ohos:okble:1.0.0')
   ......  
}

在sdk6，DevEco Studio 2.2 Beta1下项目可直接运行如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

使用说明

扫描外设

OKBLEScanManager scanManager = new OKBLEScanManager(this);
 scanManager.setScanCallBack(scanCallBack);
    DeviceScanCallBack scanCallBack = new DeviceScanCallBack() {
        @Override
        public void onBLEDeviceScan(BLEScanResult device, int rssi) {
           LogUtils.e(" scan:"+device.toString());
       }

       @Override
       public void onFailed(int code) {
          switch (code) {
                case DeviceScanCallBack.SCAN_FAILED_BLE_NOT_SUPPORT:
                    showToast("该设备不支持BLE");
                    break;
                case DeviceScanCallBack.SCAN_FAILED_BLUETOOTH_DISABLE:
                    showToast("请打开手机蓝牙");
                    break;
                case DeviceScanCallBack.SCAN_FAILED_LOCATION_PERMISSION_DISABLE:
                    showToast("请授予位置权限以扫描周围的蓝牙设备");
                    break;
                case DeviceScanCallBack.SCAN_FAILED_LOCATION_PERMISSION_DISABLE_FOREVER:
                    showToast("位置权限被您永久拒绝,请在设置里授予位置权限以扫描周围的蓝牙设备");
                    break;
            }
       }

       @Override
       public void onStartSuccess() {
       }
   };

连接外设

OKBLEDevice okbleDevice=new OKBLEDeviceImp(mContext,bleScanResult);
//okbleDevice=new OKBLEDeviceImp(mContext);
//okbleDevice.setBluetoothDevice(mBluetoothDevice);
okbleDevice.addDeviceListener(this);
okbleDevice.connect(true);//true表示连接断开后OKBLE的会自动重连

APP主动断开连接

okbleDevice.disConnect(false); //false表示断开后不需要OKBLE的自动重连; disConnect断开后,可以使用okbleDevice.connect()重新连接回来

APP清除连接

okbleDevice.remove(); //remove会清除连接的外设信息; 重新连接前需要重新调用setBleScanResult/setBluetoothDevice 来设置外设信息

数据通讯

  // Read
  application.okbleDevice.addReadOperation(characteristicModel.getUuid(), new OKBLEOperation.ReadOperationListener() {

发送大数据(应用场景1:OAD/空中升级) OAD原理其实就是把固件(如.bin文件)加载成byte[]数组,然后把byte[]数据分段发送给设备,以下代码演示了主要分段部分,OAD细节不展示(如每个包的整合),根据需求会有变化

        final int sendInterval=50;//每个包之间的发送间隔,有些手机会因为发送太快而导致蓝牙奔溃,OAD失败率很高,可以适当增大,如80-100;
        okbleDevice.setOperationInterval(sendInterval);
        byte[] oadValues=loadBytesFromFile(filePath);
        final int blockSize=20;//表示一个包发送20个字节
        final int blockCount= (int) Math.ceil(oadValues.length*1.0f/blockSize);//发送的总包数
        percent=0;
        for (int i=0;i<blockCount;i++){
            byte[] value=new byte[blockSize];
            System.arraycopy(oadValues,i*blockSize,value,0,blockSize);
            okbleDevice.addWriteOperation(OAD_WRITE_UUID, value, new OKBLEOperation.WriteOperationListener() {
                @Override
                public void onWriteValue(byte[] value) {
                    percent++;
                    float progress=percent*1.0f/blockCount;
                    int leftSeconds= (int) ((sendInterval*blockCount)/1000*(1-progress));              
                    HiLog.error(LABEL, "OAD 进度:"+progress+" 剩余时间:"+leftSeconds +"秒");
                }

                @Override
                public void onFail(int code, String errMsg) {
                    HiLog.error(LABEL, " OAD failed");
                    okbleDevice.clearOperations();
                    break;
                }

                @Override
                  public void onExecuteSuccess(OKBLEOperation.OperationType type) {
                }
            });
        }

                }
            });
        }

    scanManager.setBeaconScanCallback(scanCallBack);
    OKBLEBeaconManager.OKBLEBeaconScanCallback scanCallBack = new OKBLEBeaconManager.OKBLEBeaconScanCallback() {

            int value[] = scanedResults.put(beacon.getIdentifier(), beacon);
            new EventHandler(EventRunner.getMainEventRunner()).postTask(new Runnable() {
                @Override
                public void run() {
                    if (value[1] == 1) {
                        //这是新增数据
                        provider.notifyDataChanged();
                    } else {
                        //这是重复数据,刷新rssi
                        int index = value[0];
                        updatePosition(index);
                    }
                }
