Thanx u guys now i understood
One thing though
The VALUE for the pin number doesn't even have to be realistic. 255 works as well as any value from 0 to 13.
Are u saying it need not be any pin no.? say a pin no. 2(as Tx) and a pin no. 255(as Rx) on the transmitter side Arduino? because I really dont want to waste a pin which i don't use as Tx/Rx in case of SoftwareSerial.
From my understanding both rx and tx are defined merely for calling the function in SoftwareSerial and you basically don't use rx pin in case of Transmitter Arduino?
Thanx for the accurate reply. That was what I was looking for
