2 serial ports

I would like to send/receive serial from a roomba over the tx/rx pins on a bluetooth arduino and use the bluetooth connection to send me serial monitor feedback.

Is it possible to write serial commands to two different outputs? And how do I address them individually?

thank you

Look for SoftwareSerial, or use a Mega board, which has 4 hardware serial ports.

Hi

Is mega the only board that can do multiple serial?

thanks

In hardware, yes.

Hi

I looked at the (new)softWareSerial, that would do the trick I suppose.

So the BT interface and the tx/rx pins on a bluetooth arduino just mirrors each other?

Maybe somebody can recommend the right solution:

I need to send and receive serial from the roomba over a cable and pass on commands and feedback wirelessly to/from my computer.

I thought a BT arduino would be perfect, but maybe better with a Mega with a zigBee or BT shield?

thank you

I can't see any reason why software serial wouldn't work for this application.
