style="text-indent:25px">BLE藍牙模塊智能鎖方案：智能門禁鎖是在原有門禁系統(tǒng)的基礎上，增加低功耗藍牙透傳模塊，實現(xiàn)手機藍牙協(xié)議對接。智能手機通過APP調(diào)用藍牙服務，發(fā)送指令，智能門禁鎖接收藍牙指令，繼而控制智能門禁鎖的開關。藍牙智能鎖方案說明：智能鎖中內(nèi)置BLE藍牙模塊，手機通過APP讀取智能鎖藍牙信息，嘗試配對，并發(fā)送開鎖請求到服務器端，服務器端向手機發(fā)送開鎖指令，手機接受到指令，通過藍牙再把指令發(fā)送給智能鎖進行解鎖。藍牙MAC地址掃描打印方案：藍牙MAC地址掃描打印解決方案是包含藍牙MAC地址讀取設備、MAC地址讀取軟件、MAC地址管理軟件、二維碼生成軟件、二維碼打印驅(qū)動的一整套解決方案。</p><p style="text-indent:25px">隨著無線產(chǎn)品的應用越來越普遍，其中常用的就是藍牙無線技術了，但現(xiàn)在其實很多環(huán)境因素都有一定的干擾，無線模塊的抗干擾能力是無法進行具體數(shù)值化，所以一般也不會寫入規(guī)格書。同一發(fā)射功率和接收靈敏度的條件下，那么抗干擾能力更強的可以傳輸?shù)木嚯x會更遠。相同頻段或者惡劣環(huán)境也能對它產(chǎn)生很不好的干擾，在能不改變環(huán)境的情況，我們能操作什么？?在BLE藍牙模塊上，應選擇合理的元器件，特別是選擇硬件抗干擾方法的過程中，應當以系統(tǒng)相關的參數(shù)為基礎來進行相關元器件的選擇，這樣會極大的提供整個系統(tǒng)的干擾性能。BLE藍牙模塊可用于無線呼叫系統(tǒng)、無線排隊機、醫(yī)療器皿;</p><div

style="text-indent:25px">眾所周知，物聯(lián)時代，無線連接成為基本要求。在這個時代下，越來越多的物體將被連接到互聯(lián)網(wǎng)，并較終實現(xiàn)到主控端/云端的連接。隨著無線技術的迅速發(fā)展，整個市場已經(jīng)站在了物聯(lián)網(wǎng)新時代爆發(fā)的前夜。無論生活、工作，還是商業(yè)場景中，通過物聯(lián)網(wǎng)連接起來的萬物將以用戶為中心提供智能化的服務，由此也將催生一個巨大的市場。物聯(lián)網(wǎng)的關鍵是數(shù)以百萬計的設備，他們會集中向系統(tǒng)傳輸數(shù)據(jù)。這些數(shù)據(jù)所包含的信息可能是各種變量，如溫濕度、用戶的位置、貨物的移動等。捕捉的信息隨后會被傳輸至云端或其他設備（即各種“物”）進行數(shù)據(jù)交換或分析。這也意味著市場對高性能、***的物聯(lián)網(wǎng)無線模塊需求也將呈現(xiàn)增長趨勢。在成功連接設備的過程中，連接性的角色至關重要，選擇范圍也很廣：如BLE藍牙模塊、Wi-Fi、RFID、NFC等等。我們在解決方案的選取會考慮若干因素，包括環(huán)境因素、傳感器密度、需要的連接距離和傳輸速度等。BLE藍牙模塊應用于實時性要求比較高，但對數(shù)據(jù)速率要求不是特別高的產(chǎn)品。溫州電腦藍牙模塊代理廠家</p><p
