style="text-indent:25px">BLE藍(lán)牙模塊本身是一項(xiàng)不錯的技術(shù)，而真正令其被普遍采納的原因，是這項(xiàng)技術(shù)在恰當(dāng)?shù)臅r間作出了適當(dāng)?shù)耐讌f(xié)。雖然是一項(xiàng)相對新的標(biāo)準(zhǔn)，但已經(jīng)加入BLE藍(lán)牙模塊技術(shù)的產(chǎn)品設(shè)計數(shù)量已遠(yuǎn)遠(yuǎn)超過其他無線技術(shù)在相同階段時的產(chǎn)品數(shù)量。主要是因?yàn)樗{(lán)牙技術(shù)有以下幾個特征：從外形設(shè)計到使用方式，一切皆以非常低功耗為設(shè)計目標(biāo)。為了減少功耗，BLE藍(lán)牙模塊設(shè)備大部分時間會處于睡眠模式。當(dāng)活動發(fā)生時，設(shè)備會自動被喚醒并且向網(wǎng)關(guān)、個人電腦或智能手機(jī)發(fā)送一則短訊。較大/峰值功耗不超過15毫安，平均功耗約為1微安。使用時的功耗被降低到傳統(tǒng)藍(lán)牙的十分之一。在使用較少的應(yīng)用中，一粒紐扣電池就能維持5至10年的穩(wěn)定運(yùn)行。</p><p style="text-indent:25px">BLE藍(lán)牙模塊在物聯(lián)網(wǎng)領(lǐng)域應(yīng)用普遍的原因：BLE藍(lán)牙模塊支持3毫秒內(nèi)的連接設(shè)置與數(shù)據(jù)傳輸。因此，在短時突發(fā)通信中，應(yīng)用可以在數(shù)毫秒內(nèi)建立連接并且傳輸經(jīng)過驗(yàn)證的數(shù)據(jù)，然后迅速斷開連接。?調(diào)制指數(shù)的增加使BLE藍(lán)牙模塊的較大距離達(dá)到100米以上。?BLE藍(lán)牙模塊在所有數(shù)據(jù)包上使用強(qiáng)大的24位CRC保證極好的抗干擾能力。BLE藍(lán)牙模塊使用CCM的完整AES－128加密技術(shù)提供強(qiáng)大的數(shù)據(jù)包加密與驗(yàn)證，確保通信的安全。BLE在從屬設(shè)備的每個數(shù)據(jù)包上使用32位訪問地址，從而可以連接數(shù)十億臺設(shè)備。這一技術(shù)專為一對一連接而優(yōu)化，同時在一對多連接時將使用星型拓?fù)浣Y(jié)構(gòu)。憑借BLE藍(lán)牙模塊功率控制，發(fā)射器可以自行調(diào)整其傳輸功率或者由對端設(shè)備請求更改其傳輸功率。</p><div
