I use an Arduino Mega, WiFi ESP8266 chip to configure the WiFi I tried with 3.3V and I used the Blink example and its keep showing me this error:

Even when I tried to use 5V its show me the same error.
Please can you give me the instructions of solving the error.
also, I used board ESP the node MCU10, and ESP module also generic ESP8266 and the port i choose the correct one.
