says

Get the rssi info after station connected to AP.

Which device is "station" and which is "AP" here? My ESP32 opens an AP and my smartphone connects to it. I need to get the rssi of this connection. Is this the right function call? Because it does not work. What is the correct function?

When the ESP32 is connected to a WiFi Network its wireless interface is set to STA, so the function call simple grab the last RSSI frame info and store it, you can use this function to simple return the RSSI information of the ESP32 signal reception to the Router.

There is nothing more than it.

If you want to GET ALL info, you shall use:

if (esp_wifi_sta_get_ap_info(&ap_wifidata)==0){
          printf("\n\nROUTER MAC=bssid[%02x:%02x:%02x:%02x:%02x:%02x]\r\n", ap_wifidata.bssid[0], ap_wifidata.bssid[1], ap_wifidata.bssid[2], ap_wifidata.bssid[3], ap_wifidata.bssid[4], ap_wifidata.bssid[5]);
          printf("rssi=%d\r\n", ap_wifidata.rssi);
          printf("channel=%d\r\n", ap_wifidata.primary);
          printf("antenna=%d\r\n", ap_wifidata.ant);
          printf("phy_11b:1=%d\r\n", ap_wifidata.phy_11b);
          printf("phy_11g:1=%d\r\n", ap_wifidata.phy_11g);
          printf("phy_11n:1=%d\r\n", ap_wifidata.phy_11n);
          printf("phy_lr:1=%d\r\n", ap_wifidata.phy_lr);
          printf("wps:1=%d\r\n", ap_wifidata.wps);
          printf("country code=[%s] channel_start=[%d] total_channels=[%d] max_power=[%d] policy=[%d]\r\n", ap_wifidata.country.cc,ap_wifidata.country.schan, ap_wifidata.country.nchan,ap_wifidata.country.max_tx_power, ap_wifidata.country.policy);
 }

So simple, it is the same as ap_wifidata.rssi

gotcha?
