警告:不允许使用广告密钥“服务数据" [英] WARNING: The advertisement key 'Service Data' is not allowed

问题描述

我正在开发BLE外围应用程序.根据要求，广告包必须包含服务数据"字段.我已经在Android中做到了，数据包应该是这样的:

I am developing a BLE peripheral app. By requirement, the advertising packet must contain Service Data field. I have done this in Android, the packet should be like this:

0x16是此处列出的服务数据字段 https://www .bluetooth.com/specifications/assigned-numbers/generic-access-profile/

0x16 is Service Data field listed here https://www.bluetooth.com/specifications/assigned-numbers/generic-access-profile/

同一件事，我在iOS中完成.我使用BluetoothCore框架来实现蓝牙外围设备.

Same thing, I do it in iOS. I use BluetoothCore framework to implement the bluetooth peripheral.

以下是我应该用来为服务数据"字段设置值的属性:

Below is the attribute I should use to set value for Service Data field:

advertisementData[CBAdvertisementDataServiceDataKey] = <somedata>

但是我收到警告:

警告:不允许使用广告代码服务数据"

WARNING: The advertisement key 'Service Data' is not allowed

有人可以让我知道原因和解决方案吗?

Can someone let me know why and what is the solution?

推荐答案

在iOS上为外围设备做广告时，您无法指定服务数据.您只能指定服务UUID和服务名称.

You cannot specify service data when advertising a peripheral on iOS. You can only specify the service UUID and the service name.

从文档:

advertisementData

advertisementData

包含要发布的数据的可选词典. CBCentralManagerDelegate中详细说明了advertiseData词典的可能关键字.也就是说，外围设备管理器对象仅支持两个键:CBAdvertisementDataLocalNameKey和CBAdvertisementDataServiceUUIDsKey.

An optional dictionary containing the data you want to advertise. The possible keys of an advertisementData dictionary are detailed in CBCentralManagerDelegate. That said, only two of the keys are supported for peripheral manager objects: CBAdvertisementDataLocalNameKey and CBAdvertisementDataServiceUUIDsKey.

警告的解决方法是从广告数据字典中删除CBAdvertisementDataServiceDataKey.

The solution to your warning is to remove CBAdvertisementDataServiceDataKey from the advertising data dictionary.

恐怕iOS上无法解决您的要求.

I'm afraid there isn't a solution to your requirements on iOS.
