無線傳感器和執(zhí)行器的藍牙低功耗

　　對于低功耗無線傳感器網(wǎng)絡(luò)，有許多無線協(xié)議選項，但沒有一項比藍牙低能量更適合這項任務(wù)。

　　無線解決方案被用于各種苛刻的工業(yè)應(yīng)用中。技術(shù)，如無線局域網(wǎng)、經(jīng)典藍牙，IEEE 802.15.4/ZigBee無線HART，和所有提供具體的特點，因此適用于不同的應(yīng)用和具體要求。然而，這些技術(shù)并沒有為制造自動化中傳感器和執(zhí)行器的無線連接提供最佳解決方案。在這些類型的應(yīng)用中，現(xiàn)有的技術(shù)太昂貴，太慢，或者消耗太多的能量。該解決方案缺乏無線傳感器和執(zhí)行器的快速、健壯、低能量傳輸。這就是藍牙低能耗技術(shù)發(fā)揮作用的地方。

　　Bluetooth low energy technology， formerly known as Wibree， was originally developed for the high volume consumer market. Back in June 2007， Nokia and the Bluetooth SIG announced that Wibree would be integrated with Bluetooth. In June 2010， Bluetooth Core Specification v4.0 with the hallmark feature of low energy technology was published. Bluetooth technology now encompasses low energy （Bluetooth v4.0）， Classic Bluetooth， and high speed （Bluetooth 3.0 + HS）.
