Swift(OC) 蓝牙4.0（获取蓝牙设备Mac地址）

话不多说，直接上代码

OC版本

服务选择180A，特征选择2A23然后连接

/**

* 接收数据

*/

- (void)peripheral:(CBPeripheral *)peripheral didUpdateValueForCharacteristic:(CBCharacteristic *)characteristic error:(NSError *)error{

if([characteristic.UUID isEqual:[CBUUID UUIDWithString:@"2A23"]])

{

NSString*value = [NSString stringWithFormat:@"%@",characteristic.value];

NSMutableString*macString = [[NSMutableString alloc]init];

[macString appendString:[[value substringWithRange:NSMakeRange(16,2)]uppercaseString]];

[macString appendString:@":"];

[macString appendString:[[value substringWithRange:NSMakeRange(14,2)]uppercaseString]];

[macString appendString:@":"];

[macString appendString:[[value substringWithRange:NSMakeRange(12,2)]uppercaseString]];

[macString appendString:@":"];

[macString appendString:[[value substringWithRange:NSMakeRange(5,2)]uppercaseString]];

[macString appendString:@":"];

[macString appendString:[[value substringWithRange:NSMakeRange(3,2)]uppercaseString]];

[macString appendString:@":"];

[macString appendString:[[value substringWithRange:NSMakeRange(1,2)]uppercaseString]];

NSLog(@"MAC地址是macString:%@",macString);

}

}

Swift版

服务选择Device Information，特征选择System ID然后连接

//接受数据

public func peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic, error: Error?)

{

if "\(characteristic.uuid)" == "System ID"{

var strarr = String()

for readData in characteristic.value! {

strarr += String(format: "%x",readData)

}

let string:NSString = strarr as NSString

var str = string.substring(with: NSMakeRange(12,2)).uppercased()

str = str + ":"

str = str + string.substring(with: NSMakeRange(10,2)).uppercased()

str = str + ":"

str = str + string.substring(with: NSMakeRange(8,2)).uppercased()

str = str + ":"

str = str + string.substring(with: NSMakeRange(4,2)).uppercased()

str = str + ":"

str = str + string.substring(with: NSMakeRange(2,2)).uppercased()

str = str + ":"

str = str + string.substring(with: NSMakeRange(0,2)).uppercased()

print("Mac地址:" + str)

}

}
