Hello all, I am testing multiple software serial on a few Arduino ProMini units, and I am using a pre-coded sketch "Software Serial Example". However the sketch mentions:
"Receives from the hardware serial, sends to software serial. Receives from software serial, sends to hardware serial."
How could I do all my send and receive on software then between any two devices? Also, how would I test this? Could I use a simple LED connection (e.g. each time I listen for one port before giving it up and go to the other port)?
Many thanks for your help.
