iOS藍芽4 0開發 BLE

模型與corebluetooth的對應關係；

這裡主要討論模型一，這也是當前大多數手環裝置和ios 互動的方式；開發流程

1. 建立工程，匯入corebluetooth.framework

2. 初始化 cbcentralmanager 並準備掃瞄周圍藍芽裝置

//初始化    

themanager = [[cbcentralmanager alloc]initwithdelegate:self queue:nil];
//初始化完成會呼叫如下**，返回當前手機的藍芽狀態

-(void)centralmanagerdidupdatestate:(cbcentralmanager*)centralelse}}

3. 當藍芽狀態一切正常時，這時可以開始搜尋周邊裝置了，比如手環

//開始連線action

- (ibaction)startconnectaction:(id)sender 
}

//掃瞄到裝置會進入方法

-(void)centralmanager:(cbcentralmanager *)central diddiscoverperipheral:(cbperipheral *)peripheral advertisementdata:(nsdictionary *)advertisementdata rssi:(nsnumber *)rssi
}

//

掃瞄到特徵
-(void)peripheral:(cbperipheral *)peripheral diddiscovercharacteristicsforservice:(cbservice *)service error:(nserror *)error
nslog(
@"掃瞄到外設服務特徵有：%@->%@->%@
",peripheral.name,service.uuid,service.characteristics);
//獲取characteristic的值
for (cbcharacteristic *characteristic in
service.characteristics)
//電池電量
else
if([characteristic.uuid.uuidstring isequaltostring:kmi_butery])
else
if([characteristic.uuid.uuidstring isequaltostring:kmi_shake])
//裝置資訊
else
if([characteristic.uuid.uuidstring isequaltostring:kmi_device])}}
}//掃瞄到服務
-(void)peripheral:(cbperipheral *)peripheral diddiscoverservices:(nserror *)error
nslog(
@"掃瞄到外設服務：%@ -> %@
",peripheral.name,peripheral.services);
for (cbservice *service in
peripheral.services) 
nslog(
@"開始掃瞄外設服務的特徵 %@...
",peripheral.name);
}#pragma mark 裝置掃瞄與連線的**
//連線到peripherals-成功
- (void)centralmanager:(cbcentralmanager *)central didconnectperipheral:(cbperipheral *)peripheral
//連線外設失敗
-(void)centralmanager:(cbcentralmanager *)central didfailtoconnectperipheral:(cbperipheral *)peripheral error:(nserror *)error
//與外設斷開連線
- (void)centralmanager:(cbcentralmanager *)central diddisconnectperipheral:(cbperipheral *)peripheral error:(nserror *)error

6. 當我們對裝置傳送一些指令時，會在如下**裡面響應到裝置返回的資料

#pragma mark 裝置資訊處理

//掃瞄到具體的值
- (void)peripheral:(cbperipheral *)peripheral didupdatevalueforcharacteristic:(cbcharacteristic *)characteristic error:(nullable nserror *)error
nslog(
@"%@ %@
",characteristic.uuid.uuidstring,characteristic.value);
if([characteristic.uuid.uuidstring isequaltostring:kmi_step]) 
else
if([characteristic.uuid.uuidstring isequaltostring:kmi_butery])
else
if([characteristic.uuid.uuidstring isequaltostring:kmi_device])
[self.activeid stopanimating];
self.connectbtn.enabled =yes;
self.title = @"
資訊掃瞄完成";
}

7. 完整的**工程；

iOS藍芽BLE開發

藍芽是乙個標準的無線通訊協議，具有裝置成本低 傳輸距離近和功耗低等特點，被廣泛的應用在多種場合。藍芽一般分為傳統藍芽和ble兩種模式 傳統藍芽可以傳輸音訊等較大資料量，距離近 功耗相對大 而ble則用來傳輸節點資料，傳輸資料量十分小，多數情況處於休眠狀態，因而功耗十分低，被廣泛的應用於智慧型穿戴裝置...
