style="text-indent:25px">隨著新基建熱潮的興起，人工智能、物聯網以及人工智能的縱向發(fā)展，基礎連接、數字化升級、智能化控制的需求不斷增長。越來越多的智能終端設備需要實現互聯互通、數據透傳、智能控制等需求。藍牙模塊根據支持的藍牙協議分為BLE4.2藍牙模塊、BLE4.2/5.0藍牙模塊、BLE5.0藍牙模塊。需要特別說明的是，BLE藍牙模塊是低功耗藍牙模塊，發(fā)射功率為+4dBm，+8dBm，為數據傳輸藍牙模塊，*支持數據傳輸，不支持音頻傳輸。藍牙模塊是指集成藍牙功能的芯片基本電路**，用于無線網絡通訊。藍牙模塊一般是由芯片、PCB板、外圍器件構成。石家莊***功耗藍牙ble模塊怎么賣藍牙模塊根據芯片廠商分有BroadCom藍牙模塊，Dell藍牙模塊，CSR藍牙模塊。</p><div

style="text-indent:25px">BLE藍牙模塊采用FM調制方式，降低設備的復雜性等。目前藍牙技術的傳輸速率設計為1MHz，以時分方式進行全雙工通信，其基帶協議是電路交換和分組交換的組合，完全滿足電表收費中的實時性的要求。BLE藍牙模塊如此特別的原因在于它可以與現在大量移動設備進行通信。藍牙4.2BLE模塊：藍牙4.2版本改善了數據傳輸速度和隱私保護程度，可直接通過IPv6和6LoWPAN接入互聯網。在新的標準下藍牙信號想要連接或者追蹤用戶設備必須經過用戶許可，否則藍牙信號將無法連接和追蹤用戶設備。速度方面變得更加快速，兩部藍牙設備之間的數據傳輸速度提高了2.5倍，因為藍牙智能數據包的容量提高，其可容納的數據量相當于此前的10倍左右。</p><p style="text-indent:25px">藍牙模塊按照用途來分有數據藍牙模塊和語音藍牙模塊。前者完成無線數據傳輸，后者完成語音和立體聲音頻的無線數據傳輸。藍牙模塊按照芯片設計來分有flash版本和ROM版本。前者一般是BGA封裝，外置flash的，后者一般是QFN封裝，外接EEPROM。藍牙模塊根據芯片廠商分有BroadCom藍牙模塊，Dell藍牙模塊，CSR藍牙模塊；藍牙模塊根據用途分有數據藍牙模塊，串口藍牙模塊，語音藍牙模塊，車載藍牙模塊；藍牙模塊根據功率分有CLASS1,CLASS2,CLASS3；藍牙模塊根據應用和支持協議劃分主要分為經典藍牙模塊（BT）和低功耗藍牙模塊（BLE）。藍牙模塊用于短距離無線通訊，按功能分為藍牙數據模塊和藍牙語音模塊。</p><div

style="text-indent:25px">ATT層用來定義用戶命令及命令操作的數據，比如讀取某個數據或者寫某個數據。BLE協議棧中，開發(fā)者接觸比較多的就是ATT。BLE引入了attribute概念，用來描述一條一條的數據。Attribute除了定義數據，同時定義該數據可以使用的ATT命令，因此這一層被稱為ATT層。GATT用來規(guī)范attribute中的數據內容，并運用group（分組）的概念對attribute進行分類管理。沒有GATT，BLE協議棧也能跑，但互聯互通就會出問題，也正是因為有了GATT和各種各樣的應用profile，BLE擺脫了ZigBee等無線協議的兼容性困境，成了出貨量的2.4G無線通信產品。低功耗藍牙（Bluetooth

style="text-indent:25px">BLE藍牙模塊技術使用與傳統藍牙技術相同的自適應跳頻(AFH)技術，因而能確保BLE藍牙模塊能夠在住宅、工業(yè)與醫(yī)療應用中的“嘈雜”射頻環(huán)境中維持穩(wěn)定的傳輸。為了較大程度地減少使用AFH的成本與功耗，BLE藍牙模塊技術已將通道數量從傳統藍牙技術的79個1兆赫茲寬通道減少至40個2兆赫茲的寬通道。藍牙技術、無線LAN、IEEE802.15.4/無線個域網以及許多專有的無線電均使用無需認證許可的2.4千兆赫工業(yè)科學醫(yī)療（ISM）頻帶。由于共享這一無線電波空間的技術過多，因此無線性能會因干擾所引發(fā)的錯誤修正與重復傳送而下降（例如延遲時間增加和吞吐量減少等）。在要求嚴格的應用中，可通過頻率規(guī)劃與特殊的天線設計減少干擾。貴陽藍牙透傳模塊</p></p><br
