android藍牙源碼
⑴ 如何實現android藍牙自動配對連接
望你踩吶我的回答
下面是自動配對的代碼
Mainfest,xml注冊
<receiver android:name="." >
<intent-filter>
<action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
</intent-filter>
</receiver>
自己在收到廣播時處理並將預先輸入的密碼設置進去
public class extends BroadcastReceiver
{
String strPsw = "0";
@Override
public void onReceive(Context context, Intent intent)
{
// TODO Auto-generated method stub
if (intent.getAction().equals(
"android.bluetooth.device.action.PAIRING_REQUEST"))
{
BluetoothDevice btDevice = intent
.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
// byte[] pinBytes = BluetoothDevice.convertPinToBytes("1234");
// device.setPin(pinBytes);
Log.i("tag11111", "ddd");
try
{
ClsUtils.setPin(btDevice.getClass(), btDevice, strPsw); // 手機和藍牙採集器配對
ClsUtils.createBond(btDevice.getClass(), btDevice);
ClsUtils.cancelPairingUserInput(btDevice.getClass(), btDevice);
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}

⑵ Android藍牙開發代碼怎麼寫
開啟藍牙設備和設置可見時間：
privatevoidsearch(){
BluetoothAdapteradapter=BluetoothAdapter.getDefaultAdapter();
if(!adapter.isEnabled()){
adapter.enable();
}
Intentenable=newIntent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
enable.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION,3600);//3600為藍牙設備可見時間
startActivity(enable);
IntentsearchIntent=newIntent(this,ComminuteActivity.class);
startActivity(searchIntent);
}首先，需要獲得一個BluetoothAdapter，可以通過getDefaultAdapter()獲得系統默認的藍牙適配器，當然我們也可以自己指定，但這個真心沒有必要，至少我是不需要的。然後我們檢查手機的藍牙是否打開，如果沒有，通過enable()方法打開。接著我們再設置手機藍牙設備的可見，可見時間可以自定義。

⑶ 誰能給一份開發基於藍牙4.0的android的demo源碼
請參考如下WIKI頁面，基本上目前有提供的BLE的參考代碼都集中到這個頁面了：http://processors.wiki.ti.com/index.php/Category:BluetoothLE
⑷ 如何實現android藍牙開發 自動配對連接，並不彈出提示框
我就開始查找怎麼關閉這個藍牙配對提示框，後面還是偉大的android源碼幫助了我。
在源碼 BluetoothDevice 類中還有兩個隱藏方法
cancelBondProcess（）和cancelPairingUserInput（）
這兩個方法一個是取消配對進程一個是取消用戶輸入
下面是自動配對的代碼

<receiverandroid:name=".">
<intent-filter>
<actionandroid:name="android.bluetooth.device.action.PAIRING_REQUEST"/>

⑸ 關於android系統藍牙都用什麼模塊，有單獨的android驅動嗎
Android系統的源碼中藍牙部分的分布式這樣的：
1. App部分主要包括OPP和PBAP以及HFP，當然還有settings部分，代碼分布如下：
(1) /packages/app/Bluetooth/src/com/android/bluetooth/opp
(2) /packages/app/Bluetooth/src/com/android/bluetooth/pbap
(3) /packages/app/Phone/src/com/android/phone/ 中和BT相關的部分，主要是HFHS打電話相關的
(4) /packages/app/Settings/src/com/android/settings/bluetooth/ 主要是藍牙開啟，搜索，配對等
2. Framework部分主要包括BluetoothAdapter,BluetoothService，BluetoothEventLoop，BluetoothA2dpService等核心類，代碼分布如下：
(1)/frameworks/base/core/java/android/server/ 包含BluetoothService，BluetoothEventLoop等核心類，但是並沒有向用戶應用程序提供介面，屬於系統的類。
(2)/frameworks/base/core/java/android/bluetooth 包含了BluetoothAdapter, BluetoothSocket, BluetoothServerSocket等一系列類，這些類是系統向應用程序提供的介面，編寫藍牙相關的應用程序時會用到這些類，檢查BT是否打開，搜索設備等等。如果編寫藍牙應用程序，需要熟悉該部分類的功能。
(3) /frameworks/base/core/jni/ 中包含Bluetooth相關的文件，如 android_server_BluetoothService.cpp 該部分主要是java層和c/c++層進行通信的
3. Bluez部分，主要包括各個協議的實現，如A2dp，AVRCP，AVDTP，HID，HDP，PAN，DUN以及對BT host的實現，通過該部分向BT Controler部分發送HCI命令，代碼分布服下：
/external/bluetooth/bluez
4. BluetDroid部分，主要用於開關藍牙，晶元上電部分（不屬於驅動，可以算是硬體抽象層（HAL））， 代碼分布如下：
/system/bluetooth/
5. kernel部分，主要包括RFCOMM，L2CAP等協議以及HCI的實現，代碼分布如下：
/kernel/net/bluetooth/
6. driver部分，該部分代碼還真沒了解過，代碼分布：
/kernel/drivers/bluetooth/
另外，driver部分和具體晶元密切相關，有時在下面的目錄下也會有：
/vendor/
/device/

看源碼就行了，很簡單的。

⑻ 求安卓Android手機上的的藍牙串口通訊源碼！！！！
http://code.eoe.cn/789?f_section=new
以上是地址 自己去下
⑼ android_studio手機藍牙串口通信源代碼
初涉android的藍牙操作,按照固定MAC地址連接獲取Device時，程序始終是異常終止，查了好多天代碼都沒查出原因。今天改了一下API版本，突然就成功連接了。總結之後發現果然是個坑爹之極的錯誤。
為了這種錯誤拚命查原因浪費大把時間是非常不值得的，但是問題不解決更是揪心。可惜我網路了那麼多，都沒有給出確切原因。今天特此mark，希望後來者遇到這個問題的時候能輕松解決。
下面是我的連接過程，中間崩潰原因及解決辦法。
1：用AT指令獲得藍牙串口的MAC地址，地址是簡寫的，按照常理猜測可得標准格式。
2：開一個String adress= "************" //MAC地址， String MY_UUID= "************"//UUID根據通信而定，網上都有。
3：取得本地Adapter用getDefaultAdapter(); 遠程的則用getRemoteDevice(adress)； 之後便可用UUID開socket進行通信。
如果中途各種在getRemoteDevice處崩潰，大家可以查看一下當前的API版本，如果是2.1或以下版本的話，便能確定是API版本問題，只要換成2.2或者以上就都可以正常運行了~ 這么坑爹的錯誤的確很為難初學者。 唉·········· 為這種小trick浪費很多時間真是難過。
（另外有個重要地方，別忘了給manifest裡面加以下兩個藍牙操作許可權哦~）

下面附上Android藍牙操作中用固定MAC地址傳輸信息的模板，通用搜索模式日後再補刪模板：
通用搜索模式代碼模板：
簡潔簡潔方式1 demo
作用： 用VerticalSeekBar控制一個 LED屏幕的亮暗。
直接上碼咯~
⑽ Android源碼中有關藍牙配對的程序在哪些文件中
你是用的藍牙2.0，還是4.0 BLE？不管是這兩者中哪一個，android SDK都有相關sample可以學習使用，從搜索設備，建立連接，到兩端的通信都有，基本覆蓋我們要使用的所有功能。
2.0的sample是：BluetoothChat，里邊有3個.java文件，網上對它的相關講解很多，你可以參考blog.csdn.net/homebei2/article/details/6078007；
4.0的sample是：BluetoothLeGatt，如果我沒記錯的話，里邊有4個.java文件，因為google在android4.3才支持BLE的api，相對來說比較新，用的話主要是理解一些新的協議棧概念，不是很難，網上資料相對來說少些，你也可以找找看
