Mission planner will no longer connect to my rfd 900 radio modems set on com port 4 at 57600.
In the config utility I click load settings and it communicates with the modems and the settings come up,but if i go to the flight data page and click connect all i get is a timeout with an error of no heart bet packets received. yet i have not changed anything .Can communicate with the modems through the 3dr radio exe from rfdesign website. ??? Any help would be great.
