Hello,

My system keeps giving me a propeller guard detected warning, even though i dont have any propellers installed.

any idea how i can fix this?

Do you have anything atteched to the drone like lights etc?

Hello there. I am sorry for the trouble this has caused and thank you for reaching out. May we please know before having this issue did your DJI Drone had a hard landing or a crash before? May we also know if you have attached and accessory as well on the DJI Drone and kindly please try to check the propellers as well for damages for us to be able to isolate the said issue? Thank you.

You can calibrate the Forward Vision System using the Assistant Software. The details for this in the manual on page 21.

I've not come across this problem when there are no propellers installed, but I did see the message when I installed the MAS propellers as these are slightly longer than the OEM props. As I fly the FPV drone exclusively in ACRO mode this doesn't concern me, BUT, I've disabled obstacle avoidance/slowing on all my drones as it's significantly more of a hindrance than it is a help. My reasoning is that if I'm dumb enough to crash into a tree or a wall then I don't deserve to have nice things.

Hello.

i have not had any hard lands or anything like that with this drone yet.

i did install new OEM propellers, which i suspect is the problem. just dont know how to fix it.

thank you for that information. i did get new propellers, but they are OEM from dji. same size.

i will try doing the forward vision system with assistant software to see if anything gets fixed.

Unfortunately, the solution does not apply to the dji mini 4 pro because it does not support Vision Positioning Calibration using the Assistant Software. I have tried IMU calibration to no avail.

Have you found a solution to this matter? I have been experiencing the same predicament for weeks now.

Hello there. I have recently experienced this with my DJI Mini 4 Pro. I intended to calibrate the forward vision positioning sensors but only to find out that it is nor supported in this particular model.

Hello NoniSkySurfer,

Thank you for reaching out.

Different aircraft use different versions of DJI Assistant 2. We recommend downloading the DJI Assistant 2 (Consumer Drones Series) from the official DJI website to ensure compatibility. Please kindly check the download website here: https://www.dji.com/global/downl ... sumer-drones-series

Thank you for your cooperation and understanding.

Hello NoniSkySurfer,

Thank you for reaching out.

Hi there. I already downloaded the DJI Assistant Software. When I plugged the device there was no option for calibration. And when I googled the matter it was stated that the mini 4 pro does not support vision sensor calibration using the AssistantSoftware because it is supposed to automatically calibrate on its own

Hi NoniSkySurfer,

Thank you for sharing this information. We'll contact you via private message to assist with the gimbal calibration.

We appreciate your patience.
