style="text-indent:25px">阻礙BLE藍(lán)牙模塊傳輸距離的因素：1.使用高增益天線。通常，天線增益值與無線傳輸距離成正比。天線增益越高，傳輸距離越遠(yuǎn)。但是，天線增值也不可能存在無限大。2.BLE藍(lán)牙模塊的位置調(diào)整?。BLE藍(lán)牙模塊做位置的調(diào)整，比如偏移、架高，這樣BLE藍(lán)牙模塊的無線傳輸?shù)木嚯x能夠?qū)崿F(xiàn)更遠(yuǎn)。BLE藍(lán)牙模塊要實(shí)現(xiàn)良好的傳輸效果，要選好天線放置位置。放置位置可以偏高一些，盡可能做兩邊都在高處放置，要不一邊在較高地方向下輻射，減少障礙物的阻攔盡量減少信號的盲區(qū)也能實(shí)現(xiàn)更遠(yuǎn)傳輸距離;BLE藍(lán)牙模塊連接天線放置處于同一水平面，這樣的信號發(fā)送和接收的感應(yīng)面是較大的，傳輸距離也就更遠(yuǎn)。BLE藍(lán)牙模塊技術(shù)使用與傳統(tǒng)藍(lán)牙技術(shù)相同的自適應(yīng)跳頻

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)用包括：定位標(biāo)簽，資產(chǎn)追蹤，運(yùn)動及健身傳感器，醫(yī)療傳感器，智能手表，玩具等。昆明藍(lán)牙ble模塊4.0供應(yīng)商</p><p
