纵谈Android蓝牙模块与蓝牙的表达,简略的乐句是用电话与交谈向微监督发送把持命令。,并举行简略的把持消耗。单片机蓝牙模块的衔接与规划,本文绍介了Android大哥大蓝牙客户端冲突的P。进入命题:

蓝牙知识的衔接——蓝牙客户端:

Android大哥大通常是客户端的角色。强迫衔接SPP科学实验揭晓知识(衔接蓝牙模块的数字收集),客户端衔接奔流是:

1.运用registerReceiver表达BroadcastReceiver走快蓝牙使适应、搜索知识和等等传达;

    private BroadcastReceiver searchDevices = new BroadcastReceiver()
{
 

       public void onReceive(Context
context, Intent 企图) {

           String action = ();

           Bundle b = ();

           Object[] lstName = ().toArray(); 

           // 显示接纳到的极度的音讯及其详细传达

           for (int i
= 0; i < lstName.
length;
i++) {

              String keyName = lstName[i].toString();

              Log.e凯奈姆,
字母串。平稳的(凯奈姆)));

           }

           //搜索知识时,获取知识MAC地址

           if (BluetoothDevice.ACTION_FOUND平稳的(举动)
{

              BluetoothDevice device
= intent

                     .getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

              String
str= () +
 “|” +
();

              if (lstDevices幂数的(STR)
== -1)
// 避免反复添加

                  lstDevices添加(STR) // 获取知识的解释和mac地址

              adtDevices.notifyDataSetChanged();

           }

       }

    };

2.运用BlueAdatper的搜索:

    ();
3.
BroadcastReceiveronReceive()获取从搜索成为的蓝牙知识的传达(作为名字,MACRSSI)
4.
贯穿知识MAC地址达到BluetoothDevice靶子;

5.BluetoothDevice衍生出BluetoothSocket,预备SOCKET读写知识;

6.经过BluetoothSocketcreateRfcommSocketToServiceRecord()选择衔接科学实验揭晓的方式/满足必要,这是在这时运用的
      是
SPP(UUID:00001101-0000-1000-8000-00805F9B34FB)

try {     

       btSocket =
(
uuid);

    } catch (IOException
e) {

    // TODO Auto-generated
catch block

       Log.e(TAG, “Low:
Connection failed.”
, e);     

    }

成后的门路:

try {

    btSocket.connect();            

    Log.e(TAG, 
BT connection established, data transfer link open.”
);

    ;//应用自定义功用举行蓝牙表达处置

} catch (IOException
e) {

    Log.e(TAG, 
Connection failed.”
, e); 

    setTitle(衔接倒闭..”);

}  

接近末期的(倘若体系还无婚配,体系会志愿地球杆。),运用

  BluetoothSocketgetInputStream()getOutputStream()读写蓝牙知识。

 景象和使安定可以价值一点钟孤独的穿成串来变卖。~
当心:读取串行缓冲剂必需前后读取。,用不着使安定。
 

理由超过7步逐次走后来,你会发展Android蓝牙模块是什么?。

涌现成绩:

        在第6普通初学者会弄错。: 处死.connect()发作Connection
refused

处死不克不及在这个时辰做完,怎么办怎么办呢?

因而这块儿debug找寻互联网网络上的袭击,总算在Google必然的走出旧明的方式,尝试下一步,这如同是切实可行的的。。也即把

    btSocket用可供选择的事物方式替代建筑法。,这时运用接口1

Method m;

try {

    m = ().getMethod(“createRfcommSocket”, new Class[]
{
int.class});

    btSocket =
(BluetoothSocket) (btDev, 约整数。平稳的(1));

              } catch (牢固的破格)
E1) {

                  // TODO Auto-generated
catch block

                  ();

              } catch (NoSuchMethodException
E1) {

                  // TODO Auto-generated
catch block

                  ();

              } catch (非法移民使假释出狱破格)
{

                  // TODO Auto-generated
catch block

                  ();

              } catch (IllegalAccessException
e) {

                  // TODO Auto-generated
catch block

                  ();

              } catch (InvocationTargetException
e) {

                  // TODO Auto-generated
catch block

                  e.printStackTrace();

           } 

例如,这个成绩如同早已处理了。,顺序持续运转。。

纵然,记得后面的破格,不要急忙地距~民族决不不断地非常奇特的。

下一点钟苦差事是,让大哥大经过蓝牙与MCU蓝牙模块表达。,发送标明,经过串口显示数纸机调试辅助物。详细变卖,在mangeConnectedSocket(btSocket)方式打中变卖,衣服的胸襟启动另一点钟Activity变卖。挑剔主旨,略过。

直到这时,笔者只运用蓝牙模块作为客户端。,其时运用满足必要器?,蓝牙与MCU蓝牙模块的表达,单片机蓝牙模块就充任了满足必要端(做监听使适应,经过大哥大蓝牙衔接。为了弄清楚Android蓝牙表达,笔者接下来运用它2大哥大蓝牙表达。简略地说,执意性格一点钟蓝牙扣状物,⊙﹏⊙b

在开端的时辰,据我看来在同卵双胞点钟TI先前对先前的顺序举行天真。2切开大哥大,发展独一无二的一点钟大哥大可以扩展起来。socket衔接(强迫衔接的),另一点钟答复不活泼。理由很简略,满足必要器端顺序还无作曲。! 

从此处,启动满足必要器端顺序:翻开一点钟新的穿成串变卖

蓝牙知识的衔接——蓝牙满足必要器:

    class AcceptThread extends Thread
{

    private final BluetoothServerSocket serverSocket;

    public AcceptThread()
{

        //
Use a temporary object that is later assigned to mmServerSocket,

        //
because mmServerSocket is final 

    BluetoothServerSocket tmp=null;

    try {

//tmp = (“MyBluetoothApp”, uuid);

    Log.e(TAG, “++BluetoothServerSocket
established!++”
);

  Method listenMethod =        btAdapt.getClass().getMethod(“listenUsingRfcommOn”,

   new
  
Class[]{int.class});

    tmp = ( BluetoothServerSocket) (btAdapt,
                                                 约整数。平稳的(
1));

       } catch (牢固的破格)
e) {

           // TODO Auto-generated
catch block

           ();

       } catch (非法移民使假释出狱破格)
{

           // TODO Auto-generated
catch block

           ();

       } catch (NoSuchMethodException
e) {

           // TODO Auto-generated
catch block

           ();

       } catch (IllegalAccessException
e) {

           // TODO Auto-generated
catch block

           ();

       } catch (InvocationTargetException
e) {

           // TODO Auto-generated
catch block

           ();

       }

       serverSocket=tmp;

    }   

   public void run()
{

        //
Keep listening until exception occurs or a socket is returned

         //mState!=STATE_CONNECTED

   while(true)
{
//这是一点钟延续的测量图运行。,也可以设置mState来判别

        try {

           socket = serverSocket.accept();

           Log.e(TAG, “++BluetoothSocket
established! DataLink open.++”
);

            } catch (IOException
e) {

                break;

            }

            //
If a connection was accepted

            if (socket != null)
{

                //
Do work to manage the connection 中 a separate 穿成串)

                manageConnectedSocket();    

                try {

                  serverSocket.close();

              } catch (IOException
e) {

                  // TODO Auto-generated
catch block

                  ();

              }

                break;

            }

        }       

}

    public void cancel()
{

        try {

            serverSocket.close();

        } catch (IOException
e) { }

    }

}

安置考查:2移动用电话与交谈在同卵双胞顺序后安置和翻开。,经过蓝牙检索和衔接,考查可以成衔接。,对发牢骚交界面的双重逗留,嘿嘿

关于Android365bet体育在线投注表达那点破事

当心,这正确的事先的破格。,把socket衔接扩展的方式举行了改造

btSocket =
(
uuid);//客户端

符合的的满足必要器端顺序:

tmp =
(“MyBluetoothApp”,
 uuid);//满足必要端

这将持续重行运转安置考查。,在2大哥大上发展的那一点钟bug使消失了~2大哥大进入发牢骚交界面。

神奇~ 

bug

什么大哥大要不是作为练习衔接成地起动。,当发牢骚交界面重新提起主交界面(满足必要器端)时AcceptThread它还在运转。,当您再次衔接到另一点钟移动用电话与交谈时,您可以再次揭晓它。非常Connection
refused
。也执意说 客户端蓝牙插座2二次衔接失策~
(当心,我的客户端蓝牙衔接无放在独立的穿成串上。,相反,把它放在扣状物看门狗事情中。 

又折腾了长时间的,未发现,看来,一旦我躬身送出门,我必需重行启动顺序。。哪个杰出的的神察觉为什么?!
