Nodemcu ESP8266 sends wrong signal

What you have posted as "it replies" is a part of the protocol of the compiling-process.

This means these are messages from the Arduino-IDE and not from your ESP8266.
What do you mean with "disconnects automatically?"
Disconnecting from your WLAN-Router?
Disconnecting from Blynk?
Disconnecting from your Computer?

Please describe in more details what happens.

Start with I "click on the upload button in the arduino-IDE
and then describe in detail what happends
