Why isn't my ESP8266 RFID Reader Providing Expected Output on the Serial Monitor?
@K.L.NAGARAJU In the picture, you shared it seems like the code has not yet been uploaded in your ESP8266. Because, in the other picture you shared it shows when you upload the code the COM7 not available (orange fonts in the output console of IDE). If the code upload succeeded then how come the serial monitor COM6 reading the serial terminal? So this means the code running on ESP8266 is older. I hope this may help you to debug the issue. Thanks!
