解释特征属性(iOS和BLE) [英] Interpret Characteristic Properties (iOS and BLE)

问题描述

我正在从iPhone的BLE设备读取特征属性.

I am reading characteristic properties from a BLE device from my iPhone.

但是，我看到的某些属性(例如0xA，0x22)不在Apple提供的枚举列表中.这些属性是两个或多个枚举值的组合吗?还是来自制造商的这些自定义属性?在这方面需要指导.

However, some of the properties I am seeing (like 0xA, 0x22) are not in the enumerated list that Apple provides. Are these properties a combination of 2 or more enumerated values? Or are these custom properties from the manufacturer? Need guidance on this.

推荐答案

您可以在

代表特征可能特性的值.自从 特性可以组合，特性可以具有 设置了多个属性值.

Values representing the possible properties of a characteristic. Since characteristic properties can be combined, a characteristic may have multiple property values set.

换句话说，一个特性可能具有多个特性.例如，这具有合理的意义，即具有可以读取(CBCharacteristicPropertyRead)和写入(CBCharacteristicPropertyWrite)的特征.

In other words, a characteristic may have more than one property. That makes sense as you can, for example, have a characteristic which can be read (CBCharacteristicPropertyRead) and written to (CBCharacteristicPropertyWrite).

在这种情况下，CBCharacteristic的properties的值将是CBCharacteristicPropertyRead和CBCharacteristicPropertyWrite的按位或，即0xA.

In this case the value of CBCharacteristic's properties would be the bitwise OR of CBCharacteristicPropertyRead and CBCharacteristicPropertyWrite, which is 0xA.
