Hello!
I am using esp8266 nodemcu board (ESP-12E).
In order to check whether the device is connected to the dashboard well without connecting anything to the board, an example provided in the tutorial was uploaded to the board.
However, there is a phenomenon in which it is repeatedly reset after connecting to blynk.
All five boards I have are experiencing the same error. All five boards are unlikely to be defective. I wonder if there is a solution when this phenomenon occurs without connecting the circuit. Or I want you to check if it’s a bug in the library.
@checker please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:

As far as I know this is a power supply issue, try a different power source and make sure it’s outputting enough power and you can also use a capacitor.
Thank you for the answers.
I applied the answers you gave me to change the cables (using three) and the power supply (laptop computer & 2.0A adapter), but the same phenomenon occurs.
What other solutions can be applied?
The code you’ve posted doesn’t contain a template ID, so won’t connect to Blynk.cloud.
As your serial monitor output shows a connection to blynk.cloud then I can only conclude that the code you’ve posted has been doctored in some way - which isn’t helpful to understanding the cause of your WDT reset.
Thanks, Pete.
I understand that the code you mentioned is a code that must be written to access blink.cloud. Since it is such a natural code, the code was omitted and posted. The code was written as follows.
#define BLYNK_DEVICE_NAME "XXXXXXXX"
#define BLYNK_AUTH_TOKEN "XXXXXXXXXXXXX";
#define BLYNK_PRINT Serial
The problem from our point of view is that if people are having issues and post what they say is the code they are using - yet that code can’t possibly work as described - then we have to ask ourselves what other key pieces have been omitted or changed.
What version of the ESP core are you using, and what IDE settings are you using when you do the upload?
Can you confirm that there is nothing attached to your NodeMCU other than the USB cable that is being used for power and serial communication?
Thank you to everyone who answered.
In my case, I thought ESP8266 was reset because Wi-Fi kept failing to respond, and I handled the problem by continuously connecting it with the Blynk cloud using a timer.
Once again, thank you to everyone who answered.
