I am try to set my drone up with Herelink, Pixhawk cube with latest arducopter firmware. The Herelink has the latest firmware using QGC. I am getting numerous error messages and unable to upload a simple mission to the drone. Can anyone help? I just need a system that works. Error message are: Mission transfer failed. Retry transfer. Error. Vehicle returned error: X/Param5 has an invalid value (MAV\_MISSION\_INVALID\_PARAM5\_X), Param5: nan. GeoFence transfer failed. Retry transfer. Error: Mission write failed, vehicle failed to send final ack. Same message with rally point. Also get an audio message: “Need Mavlink 2 for item transfer” Can anyone help? ---

You’re going to have to talk with the HereLink folks about the QGC they run on that. I don’t know anything about it with regards to how it is in sync (if at all) with regular QGC. ---

Thanks for reply. Do you know if its possible to install standard latest QGC on the herelink? I have as asked the question on Herelink but not getting a reply. ---

Hi DonLakeFlyer I have managed to sort the mission sync problem. I had to add a UDP com link, now seems to be uploading missions Ok. Still get the error message about version 3.3 and higher. I don’t get that on my latest windows version. Seems the Herelink QGC needs updating? Still getting an audio message “Need Mavlink 2 for item transfer” Any idea what this could be? ---

That was fixed ages ago in QGC. > [@Russ\_Delaney1](#): > > Still getting an audio message “Need Mavlink 2 for item transfer” I’m guessing it has some bugs which have already been dealt with in regular QGC. There has been a lot of work done in QGC around ArduPilot strangeness with respect to sending capability bits for mavlink 2 support. It likely thing GeoFence/Rally are supported (they require mavlink 2) when they are not. You should be able to turn on mavlink 2 support through parameters. It’s not on by default.
