Terminal, VirtualWrite formatting of content

[Marcoryan]

I’ve read all the threads on the forum. Perhaps I am too much of a newbie so I am getting lost easily but…

I want to display serial monitor content on Blynk terminal using virtualWrite.
I want each piece of information be on a new line (Like using serial,println for the serial monitor).
Following threads I have successfully got the info to appear in terminal but without the formatting.
I looked at using terminal widget and just got confused since concensus seems to be to use virtualWrote… but then I am unclear how to force the formatting.

relevant code snippet is:

//print the "Feels like" temperature to the serial monitor
 printf("Feels like : % .0f\n", OWOC.current->apparentTemperature);
//now display it on Blynk terminal
Blynk.virtualWrite(V1, ("Feels like : % .0f\n", OWOC.current->apparentTemperature));

//print the cloud cover info to the serial monitor
printf("Current cloudcover is : % .0f\n", OWOC.current->cloudCover);
//now display it on Blynk terminal
Blynk.virtualWrite(V1, ("Current cloudcover is : % .0f\n", OWOC.current->cloudCover));

I am using iOS App, Code is running on esp32, compiled in Sketch through Arduino IDE

There is a much simpler way.
Put a jumper across the Tx snd Rx pins on your board and echo every piece of serial data to Blynk like this…

Terminal repeating...and lots of connecting to server messages

I’m a bit confused (aren’t we all!). When I use this approach I use Serial.print for everything. The function then mirrors all of the serial monitor output to the terminal as well. That way, if your device is connected to your PC by serial connection you get the output in the serial monitor, plus it appears in the Blynk terminal screen anyway. I don’t get any duplication of output. My version of Sent_serial() uses Blynk.virtualWrite instead of terminal.print(content) and terminal.flush() H…

The jumper needs to be removed before doing a sketch upload via the serial cable, but can stay in place if you are using OTA updates.

As it says in the link, I use a variable to control whether the serial output should be echoed to the terminal, which is set via a button attached to a virtual pin, but for testing purposes you could set the variable to true when it’s declared.

thanks - ill give it a go now and let you know how I get on
