style="text-indent:25px">在選擇BLE藍(lán)牙模塊時要考慮到哪些方面：銷售市場上面有許多控制模塊可提供選擇，在挑選控制模塊時，毫無疑問能夠使其變成一項(xiàng)艱巨的任務(wù)。我建議切記以下內(nèi)容：1.服務(wù)支持。服務(wù)支持十分關(guān)鍵。請保證挑選的經(jīng)銷商有著優(yōu)異的文本文檔，包含運(yùn)用手記和客戶手冊，及其“即時”資源，這種資源可以回應(yīng)您試著使藍(lán)牙模塊工作中時將會碰到的一切設(shè)計(jì)方案難題。2.經(jīng)銷商的信譽(yù)。銷售市場上面有很多控制模塊，但悲劇的是，因?yàn)榈统杀?，很多控制模塊十分有誘惑力?？墒?，“您付費(fèi)”的歷史悠久名言是恰當(dāng)?shù)摹Ｏ胂褚幌?，您的企業(yè)每一年要提升不計(jì)其數(shù)個模塊，忽然間，您所達(dá)成共識的“便宜”藍(lán)牙模塊在沒有一切警示的狀況下使用壽命停止，而且您的管路中有不計(jì)其數(shù)的訂單信息沒法完成……對業(yè)務(wù)流程來講并不是非常好。在挑選控制模塊經(jīng)銷商時，要十分有可選擇性，并開展財務(wù)盡職調(diào)查。</p><p style="text-indent:25px">BLE藍(lán)牙模塊設(shè)備可以發(fā)送兩種類型的數(shù)據(jù):廣告包和掃描響應(yīng)數(shù)據(jù)。廣告包是必要的，并且不斷地從**設(shè)備傳輸，以便被其他設(shè)備看到。當(dāng)其他設(shè)備接收到這些數(shù)據(jù)時，它們可以從**設(shè)備請求額外的數(shù)據(jù)，然后**設(shè)備發(fā)送掃描響應(yīng)數(shù)據(jù)。BLE設(shè)備可以通過兩種方式與附近的設(shè)備通信:廣播和連接。廣播是向所有收聽設(shè)備發(fā)送數(shù)據(jù)的行為。在談到廣播時，我們定義了兩個角色:廣播員和觀察者。廣播公司定期向任何愿意接收的人發(fā)送不可連接的廣告包。而觀察者則反復(fù)掃描該區(qū)域以接收數(shù)據(jù)包。然后，當(dāng)觀察者收到廣告包時，它可以請求掃描響應(yīng)數(shù)據(jù)。需要注意的是，廣播是設(shè)備一次向多個對等點(diǎn)傳輸數(shù)據(jù)的只有一個方式。BLE藍(lán)牙模塊實(shí)現(xiàn)設(shè)備之間低成本的無線互連通信。</p><div
