The reason we chose not to solve the problem this way is that it would be significantly more complicated for other teams to duplicate. The radio modems use RS422, so a converter would be necessary to get either an RS232 or TTL signal to hook up to the 2004 EduRC. Additionally, the radio modem requires an input that toggles it between command & data modes, which would have to be hooked up to a digital output on the Edu. Finally, the OTA (over-the-air) protocol is only partially documented for RC->OI communication and entirely undocumented for RC->OI. Also, using the old Edu provides an easy way to set the team number =) (otherwise it would probably have to just be a constant in the software).
