virtualWrite calls running slow after I spammed the server

[PeteKnight]

Are you sure that there’s nothing else in your code that could be an issue?

Have you tried creating another device based on this template and doing a basic test of speed using this?

If you want to echo your serial output to the terminal widget then this is the best approach…

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…

Be aware that you need to connect the Rx and Tx pins of your board together (if they are next to each other as they are on a NodeMCU or Wemos D1 Mini then you can do this with a jumper). When these pins are connected you won’t be able to upload code via the USB port unless your remove the jumper. Uploading via OTA is still possible though, if your board supports it.

Also, be aware that the Terminal widget in Blynk IoT does not retain data, so if you close the app (or maybe even if you switch away from the app) the historical terminal data won’t be visible anymore.
