淺談藍(lán)牙通信流程——（新手上路）

? ??話不多說(shuō)我們直接步入正題，下面是一個(gè)思維導(dǎo)圖：

? ??????????首先我們先與另外兩種通信方案進(jìn)行一下對(duì)比：


配對(duì)流程：

1. 注冊(cè)適配器打開(kāi)藍(lán)牙

2.搜索附近設(shè)備和已配對(duì)設(shè)備

3. 選擇未配對(duì)設(shè)備進(jìn)行配對(duì)

4.選擇已配對(duì)設(shè)備進(jìn)行連接通信


通信工作流程：?????????????????????????????????????????????????????

1.服務(wù)端先建立一個(gè)服務(wù)端套接字Socket，然后該套接字開(kāi)始監(jiān)聽(tīng)客戶端的連接。????????????????????????

2 .客戶端也建立一個(gè)socket，然后向服務(wù)端發(fā)起連接，這時(shí)候如果沒(méi)有異常就算兩個(gè)設(shè)備連接成功了。??

3.這時(shí)候客戶端和服務(wù)端都會(huì)持有一個(gè)Socket，利用該Socket可以發(fā)送和接收消息。


注冊(cè)適配器并打開(kāi)藍(lán)牙

<!-- 藍(lán)牙通訊權(quán)限 -->

<uses-permission android:name="android.permission.BLUETOOTH" />//一些配置連接藍(lán)牙的權(quán)限

<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />//進(jìn)行操作的權(quán)限

<!-- 6.0以上需要的權(quán)限 -->

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

在onCreate()方法里，獲取藍(lán)牙適配器

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

BluetoothAdapter這個(gè)類(lèi)常用的方法有：

getDefaultAdapter: 獲取本地的藍(lán)牙適配器

enable(); 打開(kāi)藍(lán)牙（不帶提示框 但是手機(jī)有自帶的。。。）

disable(); 關(guān)閉藍(lán)牙

isEnabled(): 本地藍(lán)牙是否打開(kāi)

getAddress(); 獲取自己的藍(lán)牙MAC地址

cancelDiscovery()?停止掃描

isDiscovering()?是否正在處于掃描過(guò)程中

getState()：獲取本地藍(lán)牙適配器的狀態(tài)

getScanMode(): 獲取本地藍(lán)牙適配器的當(dāng)前藍(lán)牙掃描模式。

詳細(xì)用法表

接下來(lái)為了保險(xiǎn)起見(jiàn)先判斷設(shè)備是否支持藍(lán)牙：

if(mBluetoothAdapter == null){

????????Toast.makeText(this,"本地藍(lán)牙不可用",Toast.LENGTH_SHORT).show();

????????finish(); //退出應(yīng)用

}

確認(rèn)支持藍(lán)牙的話就可以調(diào)用藍(lán)牙適配器的方法了：

String Address = bluetoothAdapter.getAddress(); //獲取本機(jī)藍(lán)牙MAC地址

String Name = bluetoothAdapter.getName(); //獲取本機(jī)藍(lán)牙名稱(chēng)

// 若藍(lán)牙沒(méi)打開(kāi)

if(!bluetoothAdapter.isEnabled()){

????????bluetoothAdapter.enable(); //打開(kāi)藍(lán)牙

}

打開(kāi)藍(lán)牙的兩種方式：

第一種打開(kāi)方法：調(diào)用enable

第二種打開(kāi)方法，調(diào)用系統(tǒng)API去打開(kāi)藍(lán)牙

mBluetoothAdapter.enable();

//不會(huì)自動(dòng)提示用戶默認(rèn)打開(kāi) 有的手機(jī)還是會(huì)提示的

Intent intent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

startActivityForResult(intent, REQUEST_OPEN_BT_CODE); //CODE值只是標(biāo)記可以更改

//會(huì)以Dialog樣式顯示一個(gè)Activity ， 我們可以在onActivityResult()方法去處理返回值


搜索附近設(shè)備和已配對(duì)設(shè)備

設(shè)置可以被搜索到

//設(shè)置可以被搜索到

//判斷藍(lán)牙適配器的當(dāng)前藍(lán)牙掃描模式

?if(mBluetoothAdapter.getScanMode()!=BluetoothAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE){

????????Intent?discoverableIntent=new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);

????????// 設(shè)置被發(fā)現(xiàn)時(shí)間，最大值是3600秒,0表示設(shè)備總是可以被發(fā)現(xiàn)的(小于0或者大于3600則會(huì)被自動(dòng)設(shè)置為120秒)

????????discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 120);

????????startActivity(discoverableIntent);

}

接下來(lái)開(kāi)始搜索附近：

判斷是否正在搜索如果是就停止搜索之類(lèi)的

if (!mBluetoothAdapter.isDiscovering()) {//判斷是否正在搜索

????????mBluetoothAdapter.startDiscovery();//開(kāi)始搜索附近設(shè)備

????????textView2.setText("正在搜索...");

} else {

????mBluetoothAdapter.cancelDiscovery();//停止搜索

}

搜索附近需要先注冊(cè)個(gè)廣播來(lái)監(jiān)聽(tīng)查詢附近藍(lán)牙設(shè)備：

藍(lán)牙掃描時(shí)，掃描到任一遠(yuǎn)程藍(lán)牙設(shè)備時(shí)，會(huì)發(fā)送此廣播。兩種廣播用一個(gè)就行

靜態(tài)注冊(cè)就是在AndroidManifest.xml文件中定義，

注冊(cè)的廣播接收器必須繼承BroadReceiver 動(dòng)態(tài)注冊(cè)就是在程序中使用Context.registerReceiver注冊(cè)。

動(dòng)態(tài)廣播

//注冊(cè)廣播

IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);//搜索到設(shè)備

registerReceiver(receiver, filter);

IntentFilter filter2 = new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);//搜索結(jié)束

registerReceiver(receiver, filter2);

靜態(tài)廣播

<!-- 廣播接收 -->

<receiver android:name="包名.類(lèi)名" >

<intent-filter android:priority="1000">

<action android:name="android.bluetooth.adapter.action.DISCOVERY_FINISHED"/>

<action android:name="android.bluetooth.device.action.FOUND" />

</intent-filter>

</receiver>

new個(gè)BroadcastReceiver來(lái)接收：

廣播一旦發(fā)送這邊就會(huì)調(diào)用onReceive（）方法

BroadcastReceiver receiver = new BroadcastReceiver() {

????????@Override

????????public void onReceive(Context context, Intent intent) {

????????????????String action = intent.getAction();

????????????????if (action.equals(BluetoothDevice.ACTION_FOUND)) {

????????????????//獲取已配對(duì)藍(lán)牙設(shè)備

????????????????????????Set<BluetoothDevice> devices = mBluetoothAdapter.getBondedDevices();

????????????????????????for (BluetoothDevice bonddevice : devices) {

????????????????????????????????mPeiDuiList.add(bonddevice);

????????????????????????????????peiDuiAdapter.notifyDataSetChanged();

????????????????????????}

????????????????????????BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

????????????????????????//判斷未配對(duì)的設(shè)備

????????????????????????if (device.getBondState() != BluetoothDevice.BOND_BONDED) {

????????????????????????????????mFuJinList.add(device);

????????????????????????????????fuJinAdapter.notifyDataSetChanged();

? ? ? ? ? ? ? ? ? ? ? ? ?}

????????????????} else if (action.equals(BluetoothAdapter.ACTION_DISCOVERY_FINISHED)) {

????????????????????????textView2.setText("搜索完成...");

????????????????}

????????}

};

我這邊是創(chuàng)建了兩個(gè)集合分別把已配對(duì)的和附近的儲(chǔ)存進(jìn)去

private ArrayList<BluetoothDevice> mPeiDuiList = new ArrayList<>();

private ArrayList<BluetoothDevice> mFuJinList = new ArrayList<>();


選擇未配對(duì)設(shè)備進(jìn)行配對(duì)

這里用到了藍(lán)牙設(shè)備BluetoothDevice

BluetoothDevice用于指代某個(gè)藍(lán)牙設(shè)備，通常表示對(duì)方設(shè)備

getName：獲得該設(shè)備的名稱(chēng)；?

getAddress：獲得該設(shè)備的地址；?

createRfcommSocketToServiceRecord：根據(jù)UUID創(chuàng)建并返回一個(gè)BluetoothSocket。

1 配對(duì)

兩個(gè)設(shè)備建立連接以后，就可以進(jìn)行一個(gè)配對(duì)的過(guò)程。

配對(duì)進(jìn)行的時(shí)候，會(huì)產(chǎn)生一個(gè)密鑰用來(lái)加密與鑒別連接。一個(gè)典型的情況是，從機(jī)設(shè)備會(huì)要求主機(jī)設(shè)備提供一個(gè)密碼來(lái)完成一個(gè)配對(duì)過(guò)程。

這個(gè)密碼可以是固定的例如“000000”，也可以是提供給上層的隨機(jī)產(chǎn)生的一個(gè)值。當(dāng)主機(jī)設(shè)備發(fā)送一個(gè)正確的密碼是，這兩個(gè)設(shè)備就會(huì)相互交換密鑰來(lái)加密并鑒別連接。

2 綁定

很多情況下，兩個(gè)設(shè)備會(huì)需要經(jīng)常性的斷開(kāi)連接，連接這樣的過(guò)程，BLE有一個(gè)安全功能，允許兩臺(tái)設(shè)備配對(duì)的時(shí)候給對(duì)方一個(gè)長(zhǎng)期的一套安全密鑰。

這種機(jī)制稱(chēng)作為綁定。允許兩個(gè)設(shè)備再次連接時(shí)不需要再次進(jìn)行配對(duì)就能從新加密與鑒別，只要他們存儲(chǔ)了這個(gè)安全密鑰。

//點(diǎn)擊附近的開(kāi)始配對(duì)

mBluetoothAdapter.cancelDiscovery();//停止搜索

String address = mFuJinList.get(position).getAddress();

Toast.makeText(MainActivity.this, mFuJinList.get(position).getName() + "配對(duì)中。。。", Toast.LENGTH_SHORT).show();

try {

????????//調(diào)用工具類(lèi)與設(shè)備配對(duì)

????????//已知自己的地址 點(diǎn)擊獲取對(duì)方的地址 配對(duì)

????????remoteDevice = mBluetoothAdapter.getRemoteDevice(address);//通過(guò)mac地址獲取藍(lán)牙設(shè)備

????????ClsUtils.createBond(remoteDevice.getClass(), remoteDevice);

} catch (Exception e) {

e.printStackTrace();

}

這里用到了一個(gè)配對(duì)工具類(lèi)ClsUtils

package com.example.lin.mylanya.utils;

import java.lang.reflect.Field;

import java.lang.reflect.Method;

import android.bluetooth.BluetoothDevice;

import android.util.Log;

public class ClsUtils {

/**

* 與設(shè)備配對(duì) 參考源碼：platform/packages/apps/Settings.git

* /Settings/src/com/android/settings/bluetooth/CachedBluetoothDevice.java

*/

static public boolean createBond(Class btClass,BluetoothDevice btDevice) throws Exception {

????????Method createBondMethod = btClass.getMethod("createBond");

????????Boolean returnValue = (Boolean) createBondMethod.invoke(btDevice);

????????return returnValue.booleanValue();

}

/**

* 與設(shè)備解除配對(duì) 參考源碼：platform/packages/apps/Settings.git

* /Settings/src/com/android/settings/bluetooth/CachedBluetoothDevice.java

*/

????????static public boolean removeBond(Class btClass,BluetoothDevice btDevice) throws Exception {

????????????????Method removeBondMethod = btClass.getMethod("removeBond");

????????????????Boolean returnValue = (Boolean) removeBondMethod.invoke(btDevice);

????????????????return returnValue.booleanValue();

????????}

}

?

選擇已配對(duì)設(shè)備進(jìn)行連接通信

通信需要?jiǎng)?chuàng)建客戶端和服務(wù)器來(lái)建立連接

服務(wù)器一般是在打開(kāi)藍(lán)牙后創(chuàng)建這里的ChatController是通信的工具類(lèi) 這個(gè)方法里面調(diào)用了服務(wù)器線程（AccepThread）的啟動(dòng)方法

if (!mBluetoothAdapter.isEnabled()) {//判斷藍(lán)牙是否打開(kāi)

????????mBluetoothAdapter.enable();//打開(kāi)藍(lán)牙

}

ChatController.getInstance().waitingForFriends(mBluetoothAdapter, handler);//等待客戶端來(lái)連接

?服務(wù)器端建立套接字，等待客戶端連接，

調(diào)用BluetoothAdapter的listenUsingRfcommWithServiceRecord方法，產(chǎn)生一個(gè)BluetoothServerSocket對(duì)象，

然后調(diào)用BluetoothServerSocket對(duì)象的accept方法，

注意accept方法會(huì)產(chǎn)生阻塞，直到一個(gè)客戶端連接建立，所以服務(wù)器端的socket的建立需要在一個(gè)子線程中去做，

藍(lán)牙客戶端套接字BluetoothSocket

BluetoothSocket是客戶端的Socket，用于與對(duì)方設(shè)備進(jìn)行數(shù)據(jù)通信。

connect：建立藍(lán)牙的socket連接；?

close：關(guān)閉藍(lán)牙的socket連接；?

getInputStream：獲取socket連接的輸入流對(duì)象；?

getOutputStream：獲取socket連接的輸出流對(duì)象；?

getRemoteDevice：獲取遠(yuǎn)程設(shè)備信息。

服務(wù)器和客戶端連接上后都需要新建一個(gè)線程進(jìn)行通信不然會(huì)線程阻塞

發(fā)送數(shù)據(jù)需要調(diào)用BluetoothSocket的getOutputStream()，接收數(shù)據(jù)需要調(diào)用getInputStream()方法

String uuid = java.util.UUID.randomUUID().toString();

一般在創(chuàng)建Socket時(shí)需要UUID作為端口的唯一性，如果兩臺(tái)Android設(shè)備互聯(lián)，則沒(méi)有什么特殊的，

如果讓非Android的藍(lán)牙設(shè)備連接Android藍(lán)牙設(shè)備，則UUID必須使用某個(gè)固定保留的UUID

Android中創(chuàng)建UUID：UUID ?uuid = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB")
