Hello. I use basic basic esp-idf wifi example code to connect the ESP32 device to the wifi in STA mode. Some other functions that I use require the wifi connection and I want to double check whether the device sucesfully connected to the wifi. In Arduino code, you can easily do that using WiFi.status() method, but I cannot find what would be the esp-idf alternative. Pseudo code:

Code: Select all


if(wifi_connected_sucesfully){
	do_http_request()
}
else{
attemt_to_reconnect()
{

If I'm not mistaken, you can do the same having a:

bool wifiConnected = false;

And taking in account the WiFi events
you can simply set in the event that global variable:

WIFI_EVENT_STA_CONNECTED then wifiConnected = true

WIFI_EVENT_STA_DISCONNECTED then wifiConnected = false

If there is another way please enlighten me. But otherwise this just adding 3 lines and checking for the wifiConnected state.

This works please look the attached file

If the example you are following is the "station" under "getting started", then just look at what the event handler is doing in that example. When a connection is made, it sets the `WIFI_CONNECTED_BIT` in the `s_wifi_event_group` event group. To determine if there's a connection, check the `WIFI_CONNECT_BIT` in that event group.
