Question

我参与了一个Android APP，它与我们公司的Bt芯片进行BLE连接和配对。 APP作为BLE核心角色，而Bt芯片则作为BLE外设角色。

当APP在Android 4.4或5.0智能手机上运行时，BLE连接和配对效果很好。当APP在Android 5.1或最新版本6.0上运行时，BLE配对由错误代码（错误代码：13）终止，而BLE连接成功。这是空气日志：

我的Bt主机程序（基于Bt芯片）收到CONNECTION_PARAMETER_UPDATE_COMP_IND事件，然后收到LE_DEVICE_DISCONNECT_COMP_IND事件。我想断开BLE的操作是由Android Bt堆栈完成的。

在Android 4.4或5.0中，没有收到CONNECTION_PARAMETER_UPDATE_COMP_IND个事件，那么问题是什么，我怎样才能在Android 5.1或6.0上成功配置BLE。任何帮助将不胜感激。

Answer 1

对于蓝牙低功耗设备的查找和配对，支持两种方式

kitkat版及以下
```
startLeScan() 
```

此方法将 BluetoothAdapter.LeScanCallback 作为参数

棒棒糖版及以上

mBluetoothLeScanner = mBluetoothAdapter.getBluetoothLeScanner();

mBluetoothLeScanner.startScan(filters, settings, mScanCallback);

您需要将回调定义为获取响应的流程

private ScanCallback mScanCallback = new ScanCallback() {
@Override
public void onScanResult(int callbackType, ScanResult result) {

}

@Override
public void onBatchScanResults(List<ScanResult> results) {

}

@Override
public void onScanFailed(int errorCode) {

}
};

Answer 2

感谢您的回复。我尝试使用startScan方法而不是startLeScan，但问题仍然存在。以下是代码的一部分：

    mBluetoothScanner = mBluetoothAdapter.getBluetoothLeScanner();
    mBluetoothScanner.startScan(mScanCallback);
    private ScanCallback mScanCallback = new ScanCallback() {
    @Override
    public void onScanResult(int callbackType, ScanResult result) {
        final byte[] scanRecord = result.getScanRecord().getBytes();
        final int rssi = result.getRssi();
        final BluetoothDevice device = result.getDevice();

        mHandler.post(new Runnable() {
            @Override
            public void run() {
                // TODO Auto-generated method stub
                //Application analyzes data in received packet.
                AdvertisingData adData = new AdvertisingData(scanRecord);
                byte[] adManufacturerData = adData.getAdManufacturerData();
                if (adManufacturerData.length < 2) {return;}

                byte[] carBrand = Arrays.copyOf(adManufacturerData, adManufacturerData.length - 2);
                byte[] carModel = Arrays.copyOfRange(adManufacturerData, adManufacturerData.length - 2, adManufacturerData.length);
                if (!Arrays.equals(carBrand, mManufacturerData)) {return;}

                mScanningFrame.setRssiInfo(rssi);

                if (rssi >= mRssi) {
                    mConnectingFrame.setCarImage(carModel);
                    mConnectedFrame.setCarImage(carModel);
                    mDisconnectedFrame.setCarImage(carModel);
                    try {
                        Thread.sleep(1000);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    showFrame(mConnectingFrame);
                    mBleDevice = device;
                    mBluetoothGatt = mBleDevice.connectGatt(getApplicationContext(), false, mGattCallback);
                    mBluetoothAdapter.stopLeScan(mLeScanCallback);
                }
            }
        });
    }

    @Override
    public void onBatchScanResults(List<ScanResult> results) {

    }

    @Override
    public void onScanFailed(int errorCode) {

    }
};

还有其他方法可以解决这个问题，或者我错过了什么？谢谢

如果您已经有了一个搜索设备的arrayList（ArrayList<Bluetoothdevice> scannedDevice），则可以选择其中之一并创建绑定。

scannedDevice.get(position).createBond();
