No Poison after the block Error in Smartconfig

[romuye123]

Basic Infos

Hardware

Hardware: ESP-12E
Core Version: 2.1.0-rc2

Description

Downloaded the latest Smartconfig SDK on iOS/android. The smartconfig works perfectly fine for the first few times. During the testing i was repeatedly trying the smartconfig even if it is connected to WIFI and the ESP got a crash with poison block error mentioned below after 4th or 5th attempt. It happens randomly. Is it not advisable to repeatedly use smartconfig even if the device is connected to WIFI ? or is there any workaround for this ?

    WiFi.mode(WIFI_STA);
    WiFi.beginSmartConfig();
    delay(200);
  
    //Wait for SmartConfig packet from mobile
    Serial.println("Waiting for SmartConfig.");
    while (!WiFi.smartConfigDone()) {
      delay(500);
      Serial.print(".");
    }
  
    Serial.println("");
    Serial.println("SmartConfig received.");
  
    //Wait for WiFi to connect to AP
    int counter = 0;
    Serial.println("Waiting for WiFi");
    while (WiFi.status() != WL_CONNECTED) {
      delay(500);
      Serial.print(".");
      counter++;
      if(counter == 60){
        break;  
      } 
    }
    counter = 0;

    if(WiFi.status() != WL_CONNECTED)
    {
      Serial.println("WiFi not Connected.");      
    }
    else
    {
      Serial.println("WiFi Connected.");
      Serial.print("IP Address: ");
      Serial.println(WiFi.localIP());
    }
}

I got this error message too. Could anyone help us?

[Khizer-Jan]

this error is probably caused due to corrupt flash memory. In order to completely format flash use following code.
https://github.com/kentaylor/EraseEsp8266Flash/blob/master/EraseFlash.ino

Hope it will solve your problem.

@Khizer-Jan it did not solved the problem.
Still the same.

wdt reset

[Khizer-Jan]

Well! it did for me. If you find any other solution ,kindly tell me about that.

Smartconfig is delivered by Espressif as a binary blob from the SDK. There's nothing in our current code base which produces the error message quoted, so I would have to guess it's coming from inside that blob. Nothing for us to do here.

我也遇到了这个问题，相同的代码使用linux可行，windows11不行
编译和上传环境都是使用 vscode+platformIO 太神奇了
