Hello,
actually i have installed the Qgroundcontrol software 3.52 from http://qgroundcontrol.com/ and after connecting to my vehicle i get the message, that my firmware 3.5.5 is not the newest, i must install 3.6.8
Which firmware is recommended?
Thanks in advance!

@rcdevil,

Please use the QGC version from our docs I shared above.
Let me know if this error remains with our version.
