ESP32 goes redundant after lost of WIFI Connection

Postby Ajiroghene » Thu Sep 26, 2019 5:40 am

Hello All,

In course of ensuring that my my esp32 project achieve stability, I did several test on it, one of which is turning off-on my Router several times. I noticed that, once the router goes off, the event callback indicates as appropriate. Once the router is turned on again, the ESP32 connects back as indicated in the log below.

However, the ESP32 at this stage does not process or execute any command in the program. it just goes into redundancy. Below below the log:

Now you see here that it is connected, but no longer active to execute the expected commands.

At this stage, how do I restart my ESP32 using the software?

I have tried this:
  1. void WIFI_Connect(){
  2.   if(WiFi.status() != WL_CONNECTED) {
  3.      WiFi.disconnect(true);delay(1000);
  4.      Serial.print("I am in Wifi connect Loop.....");
  5.      ESP.restart();
  6.   }
  7. }
but its not working.
