// If the only Service defined in the FIRST Accessory of a mult-Accessory device is the required Accessory Information Service,
|
|
// the device is said to be configured as a "Bridge". Historically there may have been a number of functional differences between bridge
|
|
// devices and non-bridge devices, but since iOS 15, it's not obvious there are any differences in functionality, with two exceptions:
|
|
|
|
// 1. Recall from Example 7 that the use of Characteristic::Name() to change the default name of an Accessory Tile
|
|
// does not work for the first Accessory defined. The Home App always displays the default name of the first Accessory Tile
|
|
// as the name of the device specified in homeSpan.begin(). However, this is not an issue when implementing a device
|
|
// as a Bridge, since the first Accessory is nothing but the Bridge itself - having the default name match the name
|
|
// of the device in this case makes much more sense. More importantly, you can now use Characteristic::Name() to change the
|
|
// default name of BOTH the LED Accessory Tiles.
|
|
|
|
// 2. Devices configured as a Bridge appear in the Home App under the main settings page that displays all Hubs and Bridges.
|
|
|
|
// The sketch below is functionally identical to Example 7, except that instead of defining two Accessories (one for the Simple 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.

|
|
// Below we replace Category::Lighting with Category::Bridges. This changes the icon of the device shown when pairing
|
|
// with the Home App, but does NOT change the icons of the Accessory Tiles. You can choose any Category you like.
|
|
// For instance, we could have continued to use Category::Lighting, even though we are configuring the device as a Bridge.
