Oh, really? I didn't know that! So, if I used SoftwareSerial, would I be using the Nano as the main microcontroller with the ESP as a sort of attachment instead of the ESP being the main microcontroller?

#51505 Simply by looking at those sketches, they are all using SoftwareSerial.
And some of them also clearly mentioned that they use external USB-Serial to do the uploads.
