本文主要以藍(lán)牙4.0做介紹,因?yàn)楝F(xiàn)在iOS能用的藍(lán)牙也就是只僅僅4.0的設(shè)備

用的庫就是core bluetooth

這里是關(guān)于藍(lán)牙的開發(fā)者官方文檔,感興趣的童鞋可以看一下點(diǎn)擊進(jìn)入 https://developer.apple.com/library/prerelease/content/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetoothOverview/CoreBluetoothOverview.html

其次就是了解一下藍(lán)牙的一些概念吧.

core bluetooth就兩個(gè)東西,peripheral和central 也就是外設(shè)和中心

如下圖所示

圖為Core Bluetooth 對(duì)象類模型
一般情況下藍(lán)牙設(shè)備為外設(shè),手機(jī)為中心,也就是在APP里面建立CBCentralManager獲取到設(shè)備的peripheral這個(gè)類, 每個(gè)peripheral又會(huì)有若干個(gè)CBService,每個(gè)CBservice里面也會(huì)有若干個(gè)CBCharateristic,每個(gè)CBCharateristic里面又會(huì)有CBDescriptor.
看圖

這句話說的真長(zhǎng).真費(fèi)勁...!! 所以從網(wǎng)上盜了圖.

藍(lán)牙外設(shè)模型
了解的差不多了,下面就是手機(jī)作為中心連接外設(shè)的步驟了:

1.第一步當(dāng)然是先建立中心管理者的角色了,成為代理,實(shí)現(xiàn)必須實(shí)現(xiàn)的代理方法也就是藍(lán)牙更新狀態(tài)的方法

2.確認(rèn)藍(lán)牙是打開的時(shí)候,我們就可以掃描周邊設(shè)備了.掃描設(shè)備的時(shí)候要同時(shí)把設(shè)備保存的數(shù)組中,以便接下來連接的時(shí)候使用,

3.掃描到我們的設(shè)備之后就可以連接了.可以根據(jù)藍(lán)牙的一些信息進(jìn)行指令連接.例如:根據(jù)藍(lán)牙名字連接等等.

4.連接上藍(lán)牙之后就會(huì)生成一個(gè)peripheral對(duì)象,這時(shí)候我們就可以拿著這個(gè)對(duì)象進(jìn)行操作了,例如查看外設(shè)信息,向這個(gè)外設(shè)讀寫信息等等.嗯,回歸正題,拿到這個(gè)peripheral對(duì)象之后

獲取peripheral的services,在獲取services里的characteristics,拿到可以讀寫的characteristic并把這個(gè)characteristic記錄下來

5.現(xiàn)在我們就可以進(jìn)行數(shù)據(jù)交互了.可以向characteristic里面寫數(shù)據(jù) 以及從characteristic讀數(shù)據(jù).嗯,讀數(shù)據(jù)也就是訂閱通知

6.完成后就可以斷開連接了.

手機(jī)作為中心連接外設(shè)的步驟也就到這里結(jié)束了.下面就開始貼代碼了.

我覺得這個(gè)代碼貼的不太好,留下github地址,下載可運(yùn)行.這樣方便多了.
