if its possible to receive serial data and just pass it trough the Arduino trough the Rx Tx ports?
I have been thinking about this in the context of receiving usb data from lets say a keyboard
wirelessly transmit it to another Arduinos pins plugged into a computers usb port? So that you would in theory exchange the usb data cables with a Arduino to Arduino wireless transfer? I know there is a lot of much easier ways to get a wireless keyboard, but the knowledge to do that exercise would be valuable in future projects.
