|
// Though we've seen in prior examples that one device can support multiple Accessories, HomeKit provides a more
|
|
// general multi-Accessory framework that is somewhat more robust and easier to use: HomeKit Bridges.
|
|
// A Bridge is a device that includes multiple Accessories, except that the FIRST defined Accessory contains
|
|
// nothing but the AccessoryInformation Service and the HAPProtcolInformation Service. When such a device is paired
|
|
// to HomeKit, it is automatically recognized as a Bridge. All of the other Accessories defined in the device are
|
|
// associated with this Bridge. If you unpair the Bridge from HomeKit, all associated Accessories are automatically
|
|
// removed.
|
|
//
|
|
// Adding, editing, and deleting the other Accessories occurs in the same manner as before, but because the device
|
|
// is paired as a Bridge, changes to the other Accessories is less likely to require you to un-pair and re-pair
|
|
// the device. HomeKit seems to be able to better process changes when they are done within a Bridge framework.
|
|
//
|
|
// One added bonus is that the HAPProtcolInformation Service only needs to be defined for the Bridge Accessory, and
|
|
// does not need to be repeated for other Accessories.
|
|
//
|
|
// Example 8 is functionally identical to Example 7, except that instead of defined two Accessories (one for the on/off
|
|
// LED and one for the dimmable LED), we define three Accessories, where the first acts as the Bridge.
|
|
|
|
// As usual, all previous comments have been deleted and only new changes from the previous example are shown.
|
|
|
|
// NOTE: To see how this works in practice, you'll need to unpair your device and re-pair it once the new code is loaded.

// except that is only contains DEV_Identify (which is derived from AccessoryInformation)
