How to implement a bridge

[leonrinkel]

Hi,

I'm trying a to implement a simple bridge including a bridged light bulb accessory. I basically added two accessories and used HAPAccessoryServerStartBridge instead of HAPAccessoryServerStart like in the following snippets. The bridge accessory works as expected, I successfully added it in the Apple Home app. Unfortunately the light bulb does not show up in the app. Instead it says "Additional Setup Required", "Add related accessories with Acme Bridge in the manufacturers app." Does a bridge really need a separate app to add accessories or is the issue somewhere else?

static HAPAccessory bridgeAccessory = { .aid = 1,
                                        .category = kHAPAccessoryCategory_Bridges,
                                        .name = "Acme Bridge",
                                        .manufacturer = "Acme",
                                        .model = "Bridge1,1",
                                        .serialNumber = "ABCDEFGH0001",
                                        .firmwareVersion = "1",
                                        .hardwareVersion = "1",
                                        .services = (const HAPService* const[]) { &bridgeAccessoryInformationService,
                                                                                  &hapProtocolInformationService,
                                                                                  &pairingService,
                                                                                  NULL },
                                        .callbacks = { .identify = IdentifyAccessory } };

static HAPAccessory lightBulbAccessory = { .aid = 2,
                                           .category = kHAPAccessoryCategory_BridgedAccessory,
                                           .name = "Acme Light Bulb",
                                           .manufacturer = "Acme",
                                           .model = "LightBulb1,1",
                                           .serialNumber = "ABCDEFGH0002",
                                           .firmwareVersion = "1",
                                           .hardwareVersion = "1",
                                           .services = (const HAPService* const[]) { &lightBulbAccessoryInformationService,
                                                                                     &lightBulbService,
                                                                                     NULL },
                                           .callbacks = { .identify = IdentifyAccessory } };

void AppAccessoryServerStart(void) {
    HAPAccessoryServerStartBridge(
        accessoryConfiguration.server, &bridgeAccessory,
        (const HAPAccessory* const[]) { &lightBulbAccessory,
                                        NULL },
        true
    );
}

Ok I just tried the same scenario using the HomeKit Accessory Simulator and the light bulb shows up immediately, so I guess a separate bridge app is not required and the issue is somewhere else.

I found out it has to be like this:

const HAPAccessory* _Nullable const* _Nullable bridgedAccessories =
    (const HAPAccessory* const[]) { &lightBulbAccessory,
                                    NULL };

void AppAccessoryServerStart(void) {
    HAPAccessoryServerStartBridge(
        accessoryConfiguration.server, &bridgeAccessory,
        bridgedAccessories, true
    );
}
