We just received and soldered up a new APM 2 autopilot. We were able to upload the Audocopter V2.5.4 once.
Now we can not connect no matter when we do. We get the message, "Cant detect your APM version. Please check your cabling".
We tried everything including setting up an entire new computer with the software .... and we get the same message.
Does the "cabling" go bad?
Is there a setting on the card that needs to be reset besides the reset button (Which we have tried several times)?
Thanks for any help anyone can give.
