我试图建立与其他手机在免提模式Android设备之间的蓝牙连接。我使用下面的code -

I am trying to establish Bluetooth connection between an Android device with other mobile phone over Handsfree profile. I am using following code -

private static final UUID MY_UUID = UUID.fromString("0000111F-0000-1000-8000-00805F9B34FB"); // UUID for Hands free profile   

// Some code...

// Get Bluetooth Adapter.
m_oBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

// Some code...

// For paired BT device, getting a connection established.
if(null != m_oBluetoothDevice)
{
    if(BluetoothDevice.BOND_BONDED == m_oBluetoothDevice.getBondState())
    {
        try
        {
            m_oBluetoothSocket = m_oBluetoothDevice.createRfcommSocketToServiceRecord(MY_UUID);     
            m_oBluetoothSocket.connect();

            Log.i(TAG, "Socket Connected");

        }
        catch(Exception e)
        {
            if(null != m_oBluetoothSocket)
            {
                Log.i(TAG, "Closing socket");
                try 
                {
                    m_oBluetoothSocket.close();
                }
                catch (Exception e1) 
                {
                    Log.i(TAG, "Error while closing socket : " + e1.getMessage());
                }
            }
        }               
    }
}

我可以用这个code创建RFCOMMSocket。

I can create RFCOMMSocket using this code.

现在我要发送AT命令基于蓝牙免提模式。例如如果其他的手机收到一个电话，我的Andr​​oid设备可以通过发送AT命令 - + CHUP拒绝这一呼吁。我不知道这是否是可以或不可以。

Now I want to send AT commands based on Bluetooth Hands-Free profile. e.g. If other mobile phone receives a phone call, my Android device can reject this call by sending AT command- "+CHUP". I am not sure whether this is possible or not.

在这一点上，我坚持。我已阅读蓝牙API的，我发现 -

At this point, I am stuck. I have read Bluetooth APIs where I found -

     BluetoothHeadset.ACTION_VENDOR_SPECIFIC_HEADSET_EVENT

我们可以用这个意向发送AT命令？这是发送AT命令基于蓝牙免提模式之有道？请人帮助我，并给我正确的方向。

Can we use this Intent for sending AT commands? Is this a proper way to send AT command based on Bluetooth Hands-Free profile? Please someone help me out and give me proper direction.

这是你们的任何投入将是对我很大的帮助。

Any input from you all will be great help for me.

在此先感谢。

推荐答案

您需要创建InputStream和OutputStream这样你就可以交谈的电​​话：

You need to create InputStream and OutputStream so you can talk to the phone:

mmInStream = m_oBluetoothSocket.getInputStream();
mmOutStream = m_oBluetoothSocket.getOutputStream();

要设置HFP连接开始传送：

To setup the HFP connection you start to send:

mmOutStream.write("AT+BRSF=20r".getBytes());

其中20为code为你支持HFP的。

Where 20 is code for what you support of HFP.

和从手机阅读：

buffer = new byte[200];
mmInStream.read(buffer);
command = new String(buffer).trim();
