style="text-indent:25px">BLE藍(lán)牙模塊由三個(gè)主要構(gòu)建模塊組成:應(yīng)用程序、主機(jī)和控制器。顧名思義，應(yīng)用程序塊是與藍(lán)牙協(xié)議棧交互的用戶應(yīng)用程序。主機(jī)覆蓋藍(lán)牙協(xié)議棧的上層。控制器覆蓋下層。主機(jī)可以通過添加一個(gè)我們稱為HCI的東西與BLE模塊通信——主機(jī)控制器接口。顯然，HCI的目的是將控制器與主機(jī)接口，而這個(gè)接口使控制器與各種主機(jī)接口成為可能。在本例中，單片機(jī)運(yùn)行應(yīng)用程序，與連接設(shè)備進(jìn)行通信，連接設(shè)備由主機(jī)和控制器組成。為此，我們使用SPI進(jìn)行通信，但是也可以使用不同的接口。BLE設(shè)備可以有兩種不同的設(shè)備，一種是中心設(shè)備，另一種是**設(shè)備。**設(shè)備通常是移動(dòng)電話或個(gè)人電腦，它們具有更高的CPU處理能力。而**設(shè)備通常是一些連接到中心設(shè)備的傳感器或低功耗設(shè)備。西寧藍(lán)牙ble模組供應(yīng)商BLE藍(lán)牙模塊在依附機(jī)器設(shè)備的每一個(gè)數(shù)據(jù)文件上應(yīng)用32位系統(tǒng)瀏覽詳細(xì)地址，進(jìn)而能夠聯(lián)接數(shù)十億臺(tái)機(jī)器設(shè)備。</p><div

style="text-indent:25px">隨著無線產(chǎn)品的應(yīng)用越來越普遍，其中常用的就是藍(lán)牙無線技術(shù)了，但現(xiàn)在其實(shí)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(jìn)行具體數(shù)值化，所以一般也不會(huì)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(qiáng)的可以傳輸?shù)木嚯x會(huì)更遠(yuǎn)。相同頻段或者惡劣環(huán)境也能對(duì)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(lán)牙模塊上，應(yīng)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(yīng)當(dāng)以系統(tǒng)相關(guān)的參數(shù)為基礎(chǔ)來進(jìn)行相關(guān)元器件的選擇，這樣會(huì)極大的提供整個(gè)系統(tǒng)的干擾性能。</p><p style="text-indent:25px">藍(lán)牙模塊的作用簡(jiǎn)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。至于什么是BLE藍(lán)牙模塊，簡(jiǎn)單來說根據(jù)應(yīng)用和支持協(xié)議劃分，藍(lán)牙主要分為經(jīng)典藍(lán)牙模塊（BT）和低功耗藍(lán)牙模塊（BLE）。經(jīng)典藍(lán)牙模塊（BT）泛指支持藍(lán)牙協(xié)議在4.0以下的模塊，一般用于數(shù)據(jù)量比較大的傳輸，如：音樂、語言等。而低功耗藍(lán)牙模塊（BLE）是指支持藍(lán)牙協(xié)議4.0或以上的模塊，就稱為BLE藍(lán)牙模塊，其較大的特點(diǎn)是成本和功耗的降低。應(yīng)用于實(shí)時(shí)性要求比較高，但對(duì)數(shù)據(jù)速率要求不是特別高的產(chǎn)品，如：消費(fèi)電子類（藍(lán)牙低周波按摩器）、可穿戴設(shè)備（手環(huán)、手表、眼鏡）、智能家居（藍(lán)牙鎖、窗簾）醫(yī)療健康類（心跳帶、血壓計(jì)、溫度計(jì)）等。低功耗藍(lán)牙模塊（BLE）是指支持藍(lán)牙協(xié)議4.0或以上的模塊，就稱為BLE藍(lán)牙模塊。</p><div

style="text-indent:25px">BLE藍(lán)牙模塊功率控制意味著什么？以模擬的情景為例：周五晚上，一對(duì)夫妻在下班后來到一家餐廳。他們一邊用餐，一邊交談。一個(gè)人在說話的時(shí)候，另一個(gè)人就在聽。如果說話者始終以較大聲音說話（即喊叫），那么說話者就會(huì)讓聽者感到不適、并留下粗魯?shù)挠∠?，不僅耗費(fèi)說話者大量的精力，還可能會(huì)逐漸損傷聽者的聽力，并且干擾附近的其他顧客。相反，如果說話者的聲音太輕，聽者將很難聽清對(duì)方說什么。說話者可能需要重復(fù)所說的內(nèi)容來讓聽者聽到。BLE藍(lán)牙模塊功率控制就是為了解決使用BLE藍(lán)牙模塊時(shí)的此類挑戰(zhàn)。兩臺(tái)BLE藍(lán)牙模塊設(shè)備建立連接后，當(dāng)一臺(tái)設(shè)備處于發(fā)射狀態(tài)時(shí)，對(duì)端設(shè)備就會(huì)處于接收狀態(tài)。通常情況下，信號(hào)器需要一定的信噪比（SNR），而且發(fā)射器的功率不能過高或過低。近年BLE藍(lán)牙模塊在物聯(lián)網(wǎng)領(lǐng)域應(yīng)用非常迅速。常州好用的藍(lán)牙ble模組</p><p style="text-indent:25px">BLE藍(lán)牙模塊具有極具智能化的控制功能。常州好用的藍(lán)牙ble模組</p><p style="text-indent:25px">BLE藍(lán)牙模塊干擾問題怎么解決？盡量避免在干擾源多的地方使用BLE藍(lán)牙模塊避開干擾源是非常有效且直接的辦法）。從硬件抗干擾技術(shù)層面考慮，可以加設(shè)低通濾波器，這樣可以向電網(wǎng)中引入高頻噪聲，并以此來降低電源干擾。濾波器是根據(jù)頻率來區(qū)分的，例如：433MHz就只能使用對(duì)應(yīng)頻率的濾波器，它較主要的功能是過濾掉其他不屬于433MHz的頻率，防止受到其他頻段的干擾，從而達(dá)到抗干擾能力的效果。屏蔽罩是BLE藍(lán)牙模塊提高的抗干擾能力盡量一個(gè)辦法，屏蔽罩的可以屏蔽掉一定外界干擾源對(duì)芯片的影響，同時(shí)也能防止無線模塊工作時(shí)對(duì)外界產(chǎn)生干擾和輻射。常州好用的藍(lán)牙ble模組</p><p
