style="text-indent:25px">什么是BLE藍(lán)牙模塊，簡單來說藍(lán)牙根據(jù)應(yīng)用和支持協(xié)議劃分主要分為經(jīng)典藍(lán)牙模塊（BT）和低功耗藍(lán)牙模塊（BLE）。經(jīng)典藍(lán)牙模塊（BT）泛指支持藍(lán)牙協(xié)議在4.0以下的模塊，一般用于數(shù)據(jù)量比較大的傳輸，如：音樂、語言等。而低功耗藍(lán)牙模塊（BLE）是指支持藍(lán)牙協(xié)議4.0或以上的模塊，就稱為BLE藍(lán)牙模塊，其大的特點(diǎn)是成本和功耗的降低。應(yīng)用于實(shí)時(shí)性要求比較高，但對(duì)數(shù)據(jù)速率要求不是特別高的產(chǎn)品，如：消費(fèi)電子類（藍(lán)牙低周波按摩器）、可穿戴設(shè)備（手環(huán)、手表、眼鏡）、智能家居（藍(lán)牙鎖、窗簾）醫(yī)療健康類（心跳帶、血壓計(jì)、溫度計(jì)）等。</p><p style="text-indent:25px">高速藍(lán)牙模塊在2009年推出，速率提高到約24Mbps，是傳統(tǒng)藍(lán)牙模塊的八倍，可以輕松用于錄像機(jī)至高清電視、PC至PMP、UMPC至打印機(jī)之間的資料傳輸。低功耗藍(lán)牙模塊（BLE）：是指支持藍(lán)牙協(xié)議4.0或更高的模塊，也稱為BLE模塊，較大的特點(diǎn)是成本和功耗的降低，應(yīng)用于實(shí)時(shí)性要求比較高的產(chǎn)品中，比如：智能家居類（藍(lán)牙鎖、藍(lán)牙燈）、傳感設(shè)備的數(shù)據(jù)發(fā)送（血壓計(jì)、溫度傳感器）、消費(fèi)類電子（遙控玩具）等。BLE藍(lán)牙模塊，是一種集成藍(lán)牙功能的PCBA板，用于短距離無線通訊，按功能分為藍(lán)牙數(shù)據(jù)模塊和藍(lán)牙語音模塊。目前市場上有很多不同尺寸、類型的藍(lán)牙模塊可供選擇。藍(lán)牙模塊主要由芯片、PCB板、外圍器件構(gòu)成。</p><div

style="text-indent:25px">藍(lán)牙模塊是什么？有什么用？什么又是BLE藍(lán)牙模塊？這些你都知道嗎？相信這個(gè)問題還是能夠難倒一部分人的，為什么呢？雖然我們平時(shí)接觸無線連接、藍(lán)牙傳輸，但是藍(lán)牙模塊還是很少見的。其實(shí)，藍(lán)牙模塊就應(yīng)用在比如手環(huán)、低周波按摩器、智能鎖等一些智能設(shè)備產(chǎn)品中。藍(lán)牙智能鎖方案說明：智能鎖中內(nèi)置BLE藍(lán)牙模塊，手機(jī)通過APP讀取智能鎖藍(lán)牙信息，嘗試配對(duì)，并發(fā)送開鎖請(qǐng)求到服務(wù)器端，服務(wù)器端向手機(jī)發(fā)送開鎖指令，手機(jī)接受到指令，通過藍(lán)牙再把指令發(fā)送給智能鎖進(jìn)行解鎖。BLE藍(lán)牙模塊選型除了關(guān)注關(guān)鍵的芯片、傳輸速率、傳輸距離、封裝尺寸、接口、天線之外，更多的還需要關(guān)注功耗值以及工作模式。藍(lán)牙模塊根據(jù)功率分有CLASS1,CLASS2,CLASS3。合肥專業(yè)售賣電腦藍(lán)牙模塊</p><p style="text-indent:25px">BLE藍(lán)牙模塊主要應(yīng)用：定位標(biāo)簽，資產(chǎn)追蹤，運(yùn)動(dòng)及健身傳感器，醫(yī)療傳感器，智能手表，遙控器，玩具等。衢州電視藍(lán)牙模塊經(jīng)銷商</p><p style="text-indent:25px">LL層是整個(gè)BLE協(xié)議棧的關(guān)鍵，也是BLE協(xié)議棧的難點(diǎn)和重點(diǎn)。像Nordic的BLE協(xié)議棧能同時(shí)支持20個(gè)link（連接），就是LL層的功勞。LL層要做的事情非常多，比如具體選擇哪個(gè)射頻通道進(jìn)行通信，怎么識(shí)別空中數(shù)據(jù)包，具體在哪個(gè)時(shí)間點(diǎn)把數(shù)據(jù)包發(fā)送出去，怎么保證數(shù)據(jù)的完整性，ACK如何接收，如何進(jìn)行重傳，以及如何對(duì)鏈路進(jìn)行管理和控制等等。LL層只負(fù)責(zé)把數(shù)據(jù)發(fā)出去或者收回來，對(duì)數(shù)據(jù)進(jìn)行怎樣的解析則交給上面的GAP或者ATT。HCI是可選的，HCI主要用于2顆芯片實(shí)現(xiàn)BLE協(xié)議棧的場合，用來規(guī)范兩者之間的通信協(xié)議和通信命令等。衢州電視藍(lán)牙模塊經(jīng)銷商</p></p><br
