homekit_service_by_type Causing Panic (Load Prohibited) #219

Open mriksman opened 3 hours ago

mriksman commented 3 hours ago

Another issue I am having after the update. The code used to work.

When I change the value (brightness) on Home App, the callback function is called

void state_change_on_callback(homekit_characteristic_t *_ch, homekit_value_t value, void *context) {
    ESP_LOGI(TAG, "%s", _ch->description);
    homekit_service_t *light_service     = homekit_service_by_type(_ch->service->accessory, HOMEKIT_SERVICE_LIGHTBULB);
    homekit_characteristic_t *brightness = homekit_service_characteristic_by_type(light_service, HOMEKIT_CHARACTERISTIC_BRIGHTNESS);

It then panics at homekit_service_t *light_service = homekit_service_by_type(_ch->service->accessory, HOMEKIT_SERVICE_LIGHTBULB);

I tried uncommenting a piece of code in my other program https://github.com/mriksman/esp32_homekit_light_switch. It too fails.

Line 625

            homekit_service_t *acc_service = homekit_service_by_type(light->service->accessory, HOMEKIT_SERVICE_ACCESSORY_INFORMATION);
            homekit_characteristic_t *acc_service_manufacture  = homekit_service_characteristic_by_type(acc_service, HOMEKIT_CHARACTERISTIC_MANUFACTURER);
