When I Learning your project, I have some questions about nfc_attendance_system_esp32 HOT 2 CLOSED

Hi @WangShuoran, WIFI_EVENT is defined here: esp-idf/components/esp_wifi/include/esp_wifi_types.h#L610

You can also take a look at this: https://github.com/espressif/esp-idf/blob/3aeb80acb66038f14fc2a7606e7516a3e2bfa6c9/docs/en/api-reference/system/esp_event.rst

from nfc_attendance_system_esp32.

I understand, Thank you for confirmation.

the pass code is setting the esp_event_handler_instance_register needed first parameter:

ESP_EVENT_DECLARE_BASE(WIFI_EVENT);
......
esp_event_handler_instance_register(WIFI_EVENT, ...);

Thank you again!
