Description

In the first Time my board gets connected to the WiFi and after 10 to 20 second the Board gets disconnected to the WiFi and unable to reconnect to the WiFi until I press the EN button in my board
and it print some error in the Serial Monitor whenever it gets disconnected from the WiFi.
Please help

Sketch

case ARDUINO_EVENT_WIFI_STA_DISCONNECTED:
      digitalWrite(wifiLed, false);
      break;
      case WIFI_PROV_STA_CONNECTING:
      {
      Serial.println("\nDisconnected. Connecting to the AP again... ");
      delay(20000);
      }
      break;
    case ARDUINO_EVENT_WIFI_STA_CONNECTED:
      Serial.printf("\nConnected to Wi-Fi!\n");
      digitalWrite(wifiLed, true);
      break;

Please update to 2.0.5, enable Core Debug to level Verbose (in the board menu) and try again. Then post the logs so we can see what is the WiFi doing. The logs you provided are from MQTT

I recommend turning on Verbose debugging as me-no-dev suggested.

May be resolved by #7344.

I did as me-no-dev said but I maked this code for ESP RAINMAKER and now it is unable to connect with the WiFi in ESP RAINMAKER and now in verbose it printing something like this :-

[    23][D][WiFiGeneric.cpp:852] _eventCallback(): Arduino Event: 0 - WIFI_READY
[   188][I][WiFiProv.cpp:142] beginProvision(): Starting AP using BLE. service_name : ESP, pop : ESP RAIN MAKER
[   188][V][WiFiGeneric.cpp:440] _arduino_event_cb(): Provisioning Initialized!
[   350][V][WiFiGeneric.cpp:283] _arduino_event_cb(): STA Started
[   336][D][WiFiGeneric.cpp:852] _eventCallback(): Arduino Event: 33 - PROV_INIT
[   363][D][WiFiGeneric.cpp:852] _eventCallback(): Arduino Event: 2 - STA_START
[   785][V][WiFiGeneric.cpp:446] _arduino_event_cb(): Provisioning Start!
[   785][D][WiFiGeneric.cpp:852] _eventCallback(): Arduino Event: 35 - PROV_START
[183372][V][WiFiGeneric.cpp:317] _arduino_event_cb(): SCAN Done: ID: 128, Status: 0, Results: 1
[183372][D][WiFiGeneric.cpp:852] _eventCallback(): Arduino Event: 1 - SCAN_DONE

So there is nothing by doing this if ESP RAINMAKER Is not Connecting to the WiFi

[me-no-dev]

Log shows only that provisioning started, but not that it completed, so it could not even start connecting to any WiFi. Maybe you need to give a bit more details on what you are doing, code you are running and so on.

Adding @sanketwadekar . I think he can help too.

1. IR issue should be unrelated to WiFi. That's up to you to solve. If debug printing causes it to work then you have a timing issue.
2. When you say "restart the Wi-Fi" do you mean restarted your router? The upcoming 2.0.6 release includes WiFi Should Reconnect For Most Reasons #7344, which may resolve that issue.

If you're looking for fellow developers to help with your code, I recommend sharing it on a GitHub repository. Obviously remove passwords, private keys, etc. No guarantees we'll fix your project though. We all have our own projects.
