I have a question: I connected to my arduino board an external device by using the built-in softwareserial library. Everything works fine.
Now, I'd like to move this and get rid of software serial and use the built in USB/serial connector to connect this device. By using this, I'm not able to establish the the connection with the device. By debugging it looks I'm sending out data, but the device does not reply to the arduino.
Now, my question is: which are the difference between the software and hardware serial in terms of settings? Do you have any suggestion in how to handle this?
Thanks a lot for your help.
