如何从 CBCharacteristic 中获取精确值?

How to get exact value from a CBCharacteristic?

<CBCharacteristic: 0x156d48cf0, UUID = BLevel, properties = 0x18, value = <32353732 380d0a>, notifying = YES>

我想提取值字段中的内容。

NSData *data = c.value; // c is of type CBCharacteristic

但是不知道是哪一种值?

您可以使用

NSData 转换为 NSString
NSString *str = [[NSString alloc] initWithData:c.value encoding:NSUTF8StringEncoding];
