Hi,

I don't unfortunately search engine doesn't work (I get white screen every time) so can't find the solution. I've created http client class for requests and I want to check internet connection before any req send, but I can't get any wifi / ip event. If register event handler instance

ESP_ERROR_CHECK(esp_event_handler_instance_register(WIFI_EVENT, ESP_EVENT_ANY_ID, event_handler, NULL, NULL));

In handler I've got switch with Wifi events but don't get any of it. Can somebody explain me what I'm doing wrong?

Thanks a lot!

Ok, I found another solution - get info from tcpip_adapter_get_ip_info(), but it doesn't look so elegant as event handlers. I can't resume sending requests in automated way.

Thanks!

But you know you can register for events multiple times in every place of code you want?
