I am trying to send NMEA messages as data over USB-serial XBee to Arduino to control a robot.

I can open a Serial object and send data from my PC - observing it with another PC and XCTU.

What is the best way to convert the numeric values (uint8) to bytes, and then write them via a Serial objects?

uint8 are bytes . You can fwrite() them directly.

Doh ; I guess that an 8-bit value could be taken to be a byte.

Thanks.

I think that the last time I used a computer whose words were not 8 bits long would have been roughly 1985, the last of my University access to a Honeywell Level/66 . I know some DSPs after used 16 bit bytes and possibly even stranger sizes (especially during the bitsliced era) but I never encountered them myself.
