iOS之藍(lán)牙4.0 BLE相關(guān)http://www.itdecent.cn/p/0a80e10bf0fc

iBeacon--- 是蘋(píng)果公司2013年9月發(fā)布的移動(dòng)設(shè)備用OS（iOS7）上配備的新功能。其工作方式是，配備有 低功耗藍(lán)牙（BLE）通信功能的設(shè)備使用BLE技術(shù)向周?chē)l(fā)送自己特有的ID，接收到該ID的應(yīng)用軟件會(huì)根據(jù)該ID采取一些行動(dòng)。

監(jiān)聽(tīng)ibeacon設(shè)備:根據(jù)proximityUUID、major 和 minor不同來(lái)區(qū)分不同的用戶(hù)再請(qǐng)求協(xié)議拿到用戶(hù)信息在把ID信息顯示出來(lái)再根據(jù)ID查找具體的信息內(nèi)容

這個(gè)場(chǎng)景是指當(dāng)你走到商家門(mén)前時(shí)，你開(kāi)啟藍(lán)牙，并用微信搖一搖周邊，那么你可以搖到優(yōu)惠券和廣告等信息。這在O2O領(lǐng)域是應(yīng)用最廣泛的。
微信搖一搖周邊是基于iBeacon來(lái)實(shí)現(xiàn)的。
首先要有一個(gè)iBeacon硬件（newbeacon）和一部藍(lán)牙4.0以及ios7以上或安卓4.3以上系統(tǒng)的手機(jī)。（會(huì)有一個(gè)專(zhuān)門(mén)部署iBeacon基站的APP）
1.申請(qǐng)微信公眾號(hào)。服務(wù)提供者向微信后臺(tái)申請(qǐng)服務(wù)，微信后臺(tái)生成一個(gè)iBeaconID,并將其映射到服務(wù)提供者提供的服務(wù)，再將iBeaconID告訴服務(wù)提供者；
2.服務(wù)提供者把第一步拿到的iBeaconID設(shè)置到iBeacon設(shè)備上，讓iBeacon設(shè)備廣播該iBeaconID；
3.用戶(hù)在該iBeacon設(shè)備的信號(hào)范圍內(nèi)打開(kāi)微信搖一搖周邊，微信App拿到該iBeaconID；
4.微信通過(guò)第三步拿到的iBeaconID，向微信后臺(tái)拉取相應(yīng)的服務(wù)，展示在搖出來(lái)的結(jié)果上；
5.用戶(hù)點(diǎn)擊搖出來(lái)結(jié)果，在微信內(nèi)嵌的瀏覽器上，會(huì)帶上用戶(hù)信息跳轉(zhuǎn)到服務(wù)提供者在第一步申請(qǐng)服務(wù)時(shí)填的url，進(jìn)入應(yīng)用頁(yè)面。

CoreBluetooth

在CoreBluetooth中，藍(lán)牙傳輸都分為兩個(gè)部分：

外圍設(shè)備CBPeripheral：
負(fù)責(zé)發(fā)布并廣播服務(wù)，告訴周?chē)闹醒朐O(shè)備它的可用服務(wù)和特征，類(lèi)似于網(wǎng)絡(luò)通信中的服務(wù)端。
中央設(shè)備CBCentral：
負(fù)責(zé)和外圍設(shè)備建立連接，一旦連接成功就可以使用外圍設(shè)備的服務(wù)和特征，類(lèi)似于網(wǎng)絡(luò)通信中的客戶(hù)端
