style="text-indent:25px">要實(shí)現(xiàn)一個(gè)BLE應(yīng)用，先需要一個(gè)支持BLE射頻的芯片，然后還需要提供一個(gè)與此芯片配套的BLE協(xié)議棧，后在協(xié)議棧上開發(fā)自己的應(yīng)用。可以看出BLE協(xié)議棧是連接芯片和應(yīng)用的橋梁，是實(shí)現(xiàn)整個(gè)BLE應(yīng)用的關(guān)鍵。那BLE協(xié)議棧具體包含哪些功能呢？簡單來說，BLE協(xié)議棧主要用來對你的應(yīng)用數(shù)據(jù)進(jìn)行層層封包，以生成一個(gè)滿足BLE協(xié)議的空中數(shù)據(jù)包，也就是說，把應(yīng)用數(shù)據(jù)包裹在一系列的幀頭（header）和幀尾（tail）中。PHY層（Physical layer物理層）。PHY層用來指定BLE所用的無線頻段，調(diào)制解調(diào)方式和方法等。PHY層做得好不好，直接決定整個(gè)BLE芯片的功耗，靈敏度以及selectivity等射頻指標(biāo)。哈爾濱藍(lán)牙透傳模塊</p></p><br /><p>文章來源地址:
