android - 蓝牙连接与 Android 应用程序自动断开

转载作者：行者123 更新时间：2023-12-04 14:18:25

我正在创建一个应用程序，它以编程方式与带有 android 应用程序的 BLE 设备连接。这是我的连接/断开代码

当用户点击连接按钮时

new Thread(new Runnable() {
            @Override
            public void run() {
                mConnecting = true;
                mConnectException = null;
                mConnectWait.close(); // Reset the condition.
                if (mConnectedGatt != null) {
                    // Reconnect to the BLE DEX adapter.
                    Logger.d(LOG_TAG, "going to connect");
                    mConnectedGatt.connect();
                    BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(deviceAddress);
                    device.connectGatt(mContext, false, mGattCallback);
                } else {
                    // Start scanning BLE devices.
                    Logger.d(LOG_TAG, "going to scan LE Devices");
                    scanLeDevice(true);
                }
                mConnectWait.block(); // Wait for connect to complete
                try {
                    if (mConnected) {
                        connectCallback.onConnectSuccess();

                    } else { // Error occurred in the connecting process
                        if (null == mConnectException) {
                            mConnectException = new BleDexException(
                                    "Failed to connect to the BLE DEX adapter",
                                    BleDexException.ERROR_BLE_CONNECT_FAILED);
                        }
                        connectCallback.onConnectFailed(mConnectException);
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }

                mConnecting = false;
            }
        }).start();

扫码:

if (!mBleScanning) {
            // Stops scanning after a pre-defined scan period.
            mHandler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    mBleScanning = false;
                    if ((null != mBleScanner) && (mBluetoothAdapter.getState() == BluetoothAdapter.STATE_ON)) {
                        mBleScanner.stopScan(mScanCallback);
                        if (mConnecting) {
                            Logger.e(LOG_TAG, "Timed out in scanning BLE devices");
                            mConnectException = new BleDexException(
                                    "Timed out in scanning BLE devices",
                                    BleDexException.ERROR_BLE_CONNECT_FAILED);
                            mConnectWait.open();
                        }
                    }
                }
            }, mBleScanPeriod);

            mBleScanning = true;
            //ScanFilter scanFilter = new ScanFilter.Builder().setServiceUuid(new ParcelUuid(DEX_SERVICE_SPP)).build();
            ScanFilter scanFilter = new ScanFilter.Builder().setDeviceName("DEXAdapter").build();
            java.util.ArrayList<ScanFilter> scanFilterList = new java.util.ArrayList<ScanFilter>();
            scanFilterList.add(scanFilter);
            ScanSettings scanSettings = new ScanSettings.Builder()
                    .setScanMode(ScanSettings.SCAN_MODE_BALANCED)
                    .build();
            if((null != mBleScanner) && (mBluetoothAdapter.getState() == BluetoothAdapter.STATE_ON))
                mBleScanner.startScan(scanFilterList, scanSettings, mScanCallback);
        }
    } else {
        Logger.d(LOG_TAG, "stop scanning. what 's the scan flag is: " + mBleScanning);
        if (mBleScanning) {
            mBleScanning = false;
            if ((null != mBleScanner) && (mBluetoothAdapter.getState() == BluetoothAdapter.STATE_ON))
                mBleScanner.stopScan(mScanCallback);
        }
    }

这是配对 Intent 的广播接收器

public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(action)) {
            if (mBtPin == null || mBtMacAddress == null) {
                return;
            }
            // Programmatically set the Bluetooth PIN.
            device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
            pairingRequestType = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_VARIANT,
                    BluetoothDevice.ERROR);
            Logger.d(LOG_TAG, "Received pairing request intent, Device mac address is: " + mBtMacAddress +
                    ". Device pairingrequest type is: " + pairingRequestType);
            if (device.getAddress().equals(mBtMacAddress)) {
                try {
                    int btpin = Integer.parseInt(mBtPin);
                    Logger.d(LOG_TAG, "Set pin to BT = " + btpin);
                    byte[] pinbytes;
                    pinbytes = ("" + btpin).getBytes("UTF-8");
                    device.setPin(pinbytes);
                    abortBroadcast();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        } else if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) {
            int state = intent.getIntExtra(BluetoothDevice.EXTRA_BOND_STATE, -1);
            switch (state) {
                case BluetoothDevice.BOND_NONE:
                    Logger.d(LOG_TAG, "Remote device is not bonded. Device: ");
                case BluetoothDevice.BOND_BONDING:
                    Logger.d(LOG_TAG, "Remote device is in bonding process");
                    break;
                case BluetoothDevice.BOND_BONDED:
                    Logger.d(LOG_TAG, "Remote device is paired");
                    BluetoothDevice bluetoothDevice = mBluetoothAdapter.getRemoteDevice(deviceAddress);
                    mConnectedGatt = bluetoothDevice.connectGatt(mContext, false, mGattCallback);
                    if (mConnectedGatt == null) {
                        Logger.e(LOG_TAG, "Failed to connect to GATT server");
                        if (mConnecting) {
                            mConnectException = new BleDexException(
                                    "Failed to connect to GATT server",
                                    BleDexException.ERROR_BLE_CONNECT_FAILED);
                            mConnectWait.open();
                        }
                    }
                    //scanLeDevice(false);
                    break;
            }
        }
    }
};

会发生什么情况，只要我按下连接按钮，它就会检查设备是否已连接？如果不是，它将开始蓝牙 LE 扫描。我添加了用于扫描设备的 ScanFilter，以便它扫描受限设备。

一旦应用程序收到扫描回调，它就会使用 createbond() 方法对设备进行配对。一旦完成并完成配对，它将尝试连接蓝牙 gatt。

所有这一切在第一次尝试时就成功了。但一段时间后，应用程序会自动断开蓝牙设备。

这是自动断开的日志

现在我稍微改变了应用程序的行为，而不是配对和连接设备，我直接连接设备而不配对。通过此更改，我看到蓝牙连接在连接 30 秒后自动断开连接。以下是日志:

提前致谢。

最佳答案

Disconnect with reason 8 表示连接超时，这是硬件问题(不是软件问题)。连接超时失败的唯一原因(至少我现在能想到的)是当两个设备尝试使用两个不同的绑定(bind) key 时。然后两者都使用不同的 key 设置加密，然后因此失败。

您可以使用空气嗅探器找出断开连接的原因或时间。
