同一设备的多个CBPeripheral [英] Multiple CBPeripheral's for same device

问题描述

使用CoreBluetooth框架访问低功耗蓝牙设备时， CBCentralManager 返回 CBPeripheral 用于外围设备.

When using the CoreBluetooth framework to access Bluetooth Low Energy devices, the CBCentralManager returns a CBPeripheral for the peripheral.

外围设备上有多个服务，我想将处理不同服务的特征值更新的代码分成多个类.因此，我需要将多个id<CBPeripheralDelegate>委托附加到外围设备.但是，这是不可能的，因为仅支持一个委托.

Multiple services are available on the peripheral and I would like to split the code that handles characteristic value updates for the different services into multiple classes. Therefore, I would need to attach multiple id<CBPeripheralDelegate> delegates to the peripheral. However, this is not possible because only one delegate is supported.

• 是否可以为同一外设获取多个CBPeripheral实例?

如果可能有多个应用程序访问同一个外围设备，那么它们会收到不同的CBPeripheral实例吗?如果是，他们是否看到其他应用程序的更新? (例如，应用程序A向特征写入值，应用程序B的委托是否还收到[–外周:didWriteValueForCharacteristic:错误:]消息?)

If it is possible that multiple applications access the same peripheral, do they receive different CBPeripheral instances? If yes, do they see updates from the other application? (Say, application A writes a value to a characteristic, does application B's delegate also receive the [– peripheral:didWriteValueForCharacteristic:error:] message?)

是否有任何精美的方法来支持将事件处理代码分为多个类?

Are there any elegant approaches to support splitting the event handling code into multiple classes?
