//把数据写到Characteristic中 //写数据 -(void)writeCharacteristic:(CBPeripheral *)peripheral characteristic:(CBCharacteristic *)characteristic value:(NSData *)value{ //打印出 characteristic 的权限,可以看到有很多种,这是一个NS_OPTIONS,就是可以同时用于好几个值,常见的有read,write,notify,indicate,知知道这几个基本就够用了,前连个是读写权限,后两个都是通知,两种不同的通知方式。 /* typedef NS_OPTIONS(NSUInteger, CBCharacteristicProperties) { CBCharacteristicPropertyBroadcast = 0x01, CBCharacteristicPropertyRead = 0x02, CBCharacteristicPropertyWriteWithoutResponse = 0x04, CBCharacteristicPropertyWrite = 0x08, CBCharacteristicPropertyNotify = 0x10, CBCharacteristicPropertyIndicate = 0x20, CBCharacteristicPropertyAuthenticatedSignedWrites = 0x40, CBCharacteristicPropertyExtendedProperties = 0x80, CBCharacteristicPropertyNotifyEncryptionRequired NS_ENUM_AVAILABLE(NA, 6_0) = 0x100, CBCharacteristicPropertyIndicateEncryptionRequired NS_ENUM_AVAILABLE(NA, 6_0) = 0x200 }; */ [self writeTolog:[NSString stringWithFormat:@"%lu", (unsigned long)characteristic.properties]]; //只有 characteristic.properties 有write的权限才可以写 if(characteristic.properties & CBCharacteristicPropertyWrite){ /* 最好一个type参数可以为CBCharacteristicWriteWithResponse或type:CBCharacteristicWriteWithResponse,区别是是否会有反馈 */ [peripheral writeValue:value forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse]; }else{ NSLog(@"该字段不可写!"); } }

//1. 创建中心设备管理者,并且设置代理 //初始化方式一:,不会提示出现"打开蓝牙允许'xxxx'连接都配件"的系统提示 _myCentralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil options:nil]; //初始化方式二 _myCentralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil];
