Android 蓝牙连接检查 mac 个地址

Question

我正在尝试比较来自配对设备的 MAC 地址，以确保它是应用程序中两个已知地址之一。我正在使用以下方法获取设备

    Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
    if (pairedDevices.size() > 0) {
        BluetoothAdapter btAdapter = BluetoothAdapter.getDefaultAdapter();
        BluetoothDevice device = btAdapter.getRemoteDevice(address1);
        mmDevice = device;
    }

所以我想做的是

if(foundMacAddress == address1){
        BluetoothDevice device = btAdapter.getRemoteDevice(address1);
}else{
        BluetoothDevice device = btAdapter.getRemoteDevice(address2);
}

但是我不确定如何检索和比较 MAC 地址。

Answer 1

您可以在 BluetoothDevice 对象上使用方法：.getBluetoothClass() , getMajorDeviceClass()，可以从pairedDevices，在你的代码中。剩下的只是字符串比较。此外，这可能对您有所帮助：How to get the bluetooth devices as a list?

Answer 2

if (!mBluetoothAdapter.isEnabled()) {
            Intent enableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
            startActivityForResult(enableIntent, REQUEST_ENABLE_BT);

你可以在 onActivityResult 函数中查看 activity 来找到 MAC 地址 像这样

public void onActivityResult(int requestCode, int resultCode, Intent data) {

        switch (requestCode) {
        case REQUEST_CONNECT_DEVICE:
            // When DeviceListActivity returns with a device to connect
            if (resultCode == Activity.RESULT_OK) {
                // Get the device MAC address
                 String add = data.getExtras()
                                     .getString(DeviceListActivity.EXTRA_DEVICE_ADDRESS);
                address= add.toString();

                 // Get the BluetoothDevice object
                BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);

            }
            break; 
}
}

Answer 3

我发现我可以循环遍历配对的设备，并以这种方式检查地址：

      BluetoothAdapter btAdapter = BluetoothAdapter.getDefaultAdapter();
        String conn = null;
        for(BluetoothDevice device : pairedDevices)
        {
            String theAddress = device.getAddress();

            if(theAddress == address1) {
                conn = address1;
            }else{
                conn = address2;
            }
            Log.d("CONNECTION: ",conn);

        }

        BluetoothDevice device = btAdapter.getRemoteDevice(conn);
        mmDevice = device;
