Android傳統(tǒng)藍(lán)牙實(shí)現(xiàn)多連接，消息發(fā)送與接收

傳統(tǒng)藍(lán)牙適用于較為耗電的操作，其中包括 Android 設(shè)備之間的流式傳輸和通信等。針對(duì)具有低功耗要求的藍(lán)牙設(shè)備，Android 4.3（API 級(jí)別 18）中引入了面向低功耗藍(lán)牙的 API 支持。因?yàn)轫?xiàng)目需求，編寫了關(guān)于傳統(tǒng)藍(lán)牙的demo,實(shí)現(xiàn)了藍(lán)牙多連，藍(lán)牙間信息發(fā)送與接收，有不對(duì)的地方，望指導(dǎo)，大家一起學(xué)習(xí)，謝謝！

大概效果如下：



安卓傳統(tǒng)藍(lán)牙多連接，消息接送#戲精上身的我#_騰訊視頻

go!go!go!

首先權(quán)限問(wèn)題

如要在應(yīng)用中使用藍(lán)牙功能，您必須聲明兩個(gè)權(quán)限。第一個(gè)是?BLUETOOTH。您需要此權(quán)限才能執(zhí)行任何藍(lán)牙通信，例如請(qǐng)求連接、接受連接和傳輸數(shù)據(jù)等。

第二個(gè)必須聲明的權(quán)限是?ACCESS_FINE_LOCATION。您的應(yīng)用需要此權(quán)限，因?yàn)樗{(lán)牙掃描可用于收集用戶的位置信息。此類信息可能來(lái)自用戶自己的設(shè)備，以及在商店和交通設(shè)施等位置使用的藍(lán)牙信標(biāo)。

如果您想讓應(yīng)用啟動(dòng)設(shè)備發(fā)現(xiàn)或操縱藍(lán)牙設(shè)置，則除了?BLUETOOTH?權(quán)限以外，您還必須聲明?BLUETOOTH_ADMIN?權(quán)限。大多數(shù)應(yīng)用只是需利用此權(quán)限發(fā)現(xiàn)本地藍(lán)牙設(shè)備。除非應(yīng)用是根據(jù)用戶請(qǐng)求修改藍(lán)牙設(shè)置的“超級(jí)管理員”，否則不應(yīng)使用此權(quán)限所授予的其他功能。

在您的應(yīng)用清單文件中聲明藍(lán)牙權(quán)限。例如：

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

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

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

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