I cant seem to post my serial monitor results to blynk terminal

@PeteKnight

Is there a valid reason for using the __VA_ARGS__ pre-processor for your serial output? It certainly makes your task of outputting the serial output to Blynk.

yes it is neccessary for my arduino to understand the incoming results from SDM120CT and TTL convertor

@PeteKnight

Also, your code makes no mention of what virtual pin your terminal widget is attached to, and you have no code to write any data to that widget. Clarification around this would be useful.

because I realized my esp8266 not functioning when its plugged in with the arduino mega 2560

@PeteKnight

If you want me to look at your code then it needs to be posted somewhere other than on a Google drive account.

I’ve made more than 13,000 posts to this group, you’ll need to be more specific!

My ESP-01 is not respoding with Arduino mega(solved)

@PeteKnight

Why are you using SoftwareSerial when your Mega has three hardware serial ports?

so I should write

#include <HardwareSerial.h>
HardwareSerial EspSerial(18, 19); // RX, TX

sorry and thanks.
