hello,
at the time i wrote the app , the gps code for waypoint was not ready ,
It is now easier to share and improve this project as I moved the code to
https://github.com/treymarc/multiwii-mavlink-gcIf you know about c coding, mavlink and gps code for waypoint (from EOSb) there is nothing that can not be done . I am now more focused on the new java gui frontend , the mwi-gc driver is free open source software , feel free to forked it on github , i would gladly help you and other may join if they see some activities and interest from other.
Regards,
Marc
