ios - 如何在 CoreBluetooth 中使用 CBCharacteristicPropertyBroadcast？

Question

我在谷歌上搜索了很长时间，但找不到关于如何在 iOS 上使用此属性的教程。有人可以发布一个小教程或一个链接吗？我真的非常感激!

我正在使用这段代码:

CBMutableCharacteristic *myCharacteristic = [[CBMutableCharacteristic alloc] initWithType:myUUID
                                                                                   properties:CBCharacteristicPropertyBroadcast
                                                                                        value:nil permissions:CBAttributePermissionsReadable];

此崩溃并出现异常:'NSInternalInconsistencyException'，原因:'CBCharacteristicPropertyBroadcast is not allowed'

Answer 1

根据 Apple's documentation on the broadcast Characteristic Property

This property is not allowed for local characteristics published via the addService: method of the CBPeripheralManager class. This means that you cannot use this property when you initialize a new CBMutableCharacteristic object via the initWithType:properties:value:permissions: method of the CBMutableCharacteristic class.
