I couldn’t find any solution for this problem , also didn’t see anyone has same problem. Some of talked about “motor command not supported” but in my case “Motor Test Command Denied”. Anyone has an idea or faced with this problem before ?
Yeah, I get the same error message…! They say it was going to work in the next release but that never happened, just like their so-called SUPPORT, that’s a big nothing tooo…!!! =)
Did you manage the problem ? And I am not sure about if the problem is QGC or PX4 versions. Did you try previous versions also ?
No I have not managed the problem, neither has anyone else to my knowledge. From what I’ve seen here they just discuss stuff… unless someone happens to know something, otherwise nothing ever gets fixed. I have no idea why it’s called a Support Forum. I think the problem is with QGC… not PX4, it was not present in Previous versions that I recall. Lot’s of people complained it didn’t work, nothing done about it, it still doesn’t work…! Wish I could help ya out bud… but you see here, no one replied that is affiliated with Forum, I’m just a some what user like you looking for answers, never found any here…!
Thank you ,at least I have learned that there is no solution so far . I am new in drones and starting academic research about power characteristics about drones. So I need a familiar program like QGC . Do you have any suggestions ?
Aziz; I am new to drones also been building this one for 2 years now, never finding any solutions to anything or problems I’ve run into, so welcome to the club…! My first mistake was buying a Chynese Clone Pixhawk Flight Controller to save $, that didn’t work, so $76.00 down the drain. Everyone boasted about Holybro products, so I spent $227.95 on a HB Pixhawk 4 Flight Controller and still nothing works…! QGC was boasted about a lot too, but it’s where all my problems came from with, Quad Copter would not arm, see the Console…! In the Console was at least 3 errors, I have no idea what the errors mean, no references any where about them, forums couldn’t reply with any thing good/bad, so Today I erased QGC and downloaded Mission Planner…! Everyone boasts about it too, so I’m giving it try…! In both GC’s the firmware loads and applies w/out any problems, the Configuration’s both go great as well… Still no ARMing of the Controller and w/out Arming there’s no Flight…? From day one, I’ve used QGC…so now I have to get into the Mission Planner program because they’re both different…! There’s YouTube videos on both plus detailed instructions at the respective sites… so hopefully it just a matter of time…?
We have solved the problem. Just need to attach GPS module on Pixhawk and click on safety swtich. After that you can control motors and no more “Motor command denied” It is working now . I hope you can also solve the problem with this way. I think QGC should indicate that safety switch should be clicked and hold on like 3 second then the led on gps will blink faster and you will be able to run the motors.
Aziz; I tried it today like you said but mine didn’t work…glad you had it working for you, I must have other problems some where else…?
I also changed to drone airframe it was like quad copter but to be sure there is no problem I changed to helicopter and run only one motor. So my test system doesn’t have to fly I just measure , rpm and thrust with some external sensor. Also be sure drone is armed mod and in my case I use manual flight mode.
hello i have the same problem my gps is attached to the fc …where is the safety switch ???
hello i have the same problem motor cannot do the rotation test error motor denied …
The remote i using skydroid T10 the throttle return is centre point n start point in centre …how do i do the setting in fc …tq
The safety switch is by the leds it’s hard to see it but it is there, if you have the correct GPS the the larger plug on it.
safety switch is also a led on GPS module , clickable led marked as ''SWITCH" on GPS module. Just click and wait 3 - 5 seconds until led blink faster.
hello friend …tqvm …i also build one unit dji naza v2 much more easy setup than this pixhawk
i need your help for the setup can you help me online with teamviewer and im from malaysia and you??
hello friend my remote is skydroid T10 the throttle lever is centre start point …how do i setup this in px4 …error throttle too high …tq
Still going through the same old “Denied” crap…it Says in the Flight Controllers Message area, "denied because it is “Not safe to fly with the USB Cable Attached to the Flight Controller…!”
And here it is December 2020 and no one has had time to assess, look, or study a solution…! So I want to thank you all for destroying my Quad Propeller Tips because my Quad flips over on to it’s back at TAKE OFF…! Maybe you should all just over to Github and goof off over there, they have 844 Issues with QGC…! None are fixed yet… “Support” what a freaking joke…! =(
You dont need the GPS module or sth. I just pulled safety switch, pressed on it and tehn modev the motor bar up. It worked.
