Just a question... When using ESP or Bluetooth modules on Uno, most of the time you use SoftwareSerial.
But on Mega or Due, you have more serial ports.
How do we read/write info to, let's say, an nRF via these ports? Omitting the SoftwareSerial?
Most of the time, I use SoftwareSerial on these boards, so the extra Serial ports are just sitting there, tumbling their thumbs...
You use them just as you would Serial, except instead of Serial you just write Serial1, Serial2, or Serial3 (depending on which of your Mega's serial ports the device is connected to). You should always use hardware serial instead of software serial if possible.
See:
"nRF" as in "**2.4GHz Transceiver Low Power nRF24L01+ **" ?
That uses SPI for communication, not Serialx.

You got me... I just thought of it as one in many serial "transceivers"...
