将心率测量服务添加到iPhone作为外围设备

// Define the heart rate service
CBMutableservice *heartRateservice = [[CBMutableservice alloc] 
      initWithType:[CBUUID UUIDWithString:@"180D"] priMary:true];

// Define the sensor LOCATIOn characteristic    
char sensorLOCATIOn = 5;
CBMutableCharacteristic *heartRateSensorLOCATIOnCharacteristic = [[CBMutableCharacteristic alloc]
      initWithType:[CBUUID UUIDWithString:@"0x2A38"] 
        properties:CBCharacteristicPropertyRead 
             value:[NSData dataWithBytesnoCopy:&sensorLOCATIOn length:1] 
       permissions:CBAttributePermissionsReadable];

// Define the heart rate reading characteristic    
char heartRateData[2]; heartRateData[0] = 0; heartRateData[1] = 60;
CBMutableCharacteristic *heartRateSensorHeartRateCharacteristic = [[CBMutableCharacteristic alloc] 
      initWithType:[CBUUID UUIDWithString:@"2A37"]
        properties: CBCharacteristicPropertyNotify
             value:[NSData dataWithBytesnoCopy:&heartRateData length:2]
       permissions:CBAttributePermissionsReadable];

// Add the characteristics to the service 
heartRateservice.characteristics = 
      @[heartRateSensorLOCATIOnCharacteristic,heartRateSensorHeartRateCharacteristic];

// Add the service to the peripheral manager    
[peripheralManager addservice:heartRateservice];

在此之后,您应该收到peripheralManager：didAddservice：error：表示添加成功的回调.您应该同样添加device information service (0x180A)最后,您应该开始做广告：

NSDictionary *data = @{
    CBAdvertisementDataLocalNameKey:@"ideviceName",CBAdvertisementDataserviceUUIDsKey:@[[CBUUID UUIDWithString:@"180D"]]};

[peripheralManager startAdvertising:data];

注意：心率服务也是我实施的第一个.好的选择.
