style="text-indent:25px">BLE協(xié)議棧詳解協(xié)議概述：所謂協(xié)議，即將指定的字節(jié)按照一定的順序排列起來，以便他人使用自己的設(shè)備時(shí)，能通過該協(xié)議同其他設(shè)備進(jìn)行通信。協(xié)議一特點(diǎn)，就是有固定的幀格式，通過該格式發(fā)送，接收者通過解讀幀格式，進(jìn)而得到新息內(nèi)容；BLE連接過程：一般通信協(xié)議，一類通信是直接發(fā)生數(shù)據(jù)，當(dāng)設(shè)備接送到數(shù)據(jù)時(shí)，直接對(duì)數(shù)據(jù)進(jìn)行解析，當(dāng)接受到的數(shù)據(jù)合法時(shí)，即為有效數(shù)據(jù)，該類型的通信協(xié)議，主要用在有線通信協(xié)議中，比如Modbus，Can通常采用的即為該類型的通信方式。湖州藍(lán)牙ble模塊4.0采購BLE藍(lán)牙模塊成本和功耗降低，應(yīng)用于實(shí)時(shí)性要求比較高。</p><div

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。</p><p style="text-indent:25px">那么藍(lán)牙模塊到底是什么呢？藍(lán)牙模塊是一種集成藍(lán)牙功能的PCBA板，主要用于無線網(wǎng)絡(luò)通訊，按功能可分為藍(lán)牙數(shù)據(jù)模塊（HY-40R201P、HY-40R204P）和藍(lán)牙語音模塊。主要由芯片、PCB板、外圍器件構(gòu)成（一般模塊具有半成品的屬性，是在芯片的基礎(chǔ)上進(jìn)行加工。換言之，藍(lán)牙模塊一般具有二次開發(fā)的特性）。如：HY-40R204P藍(lán)牙模塊則是基于TI CC2640R2F 藍(lán)牙芯片，同時(shí)PCB板集成2.4G的PCB天線。藍(lán)牙模塊的作用簡單來說就是以無線連接取代有線連接，將固定和移動(dòng)信息設(shè)備組成個(gè)人局域網(wǎng)，實(shí)現(xiàn)設(shè)備之間低成本的無線互連通信。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。</p><div
