Hi Vincent,

By drifting do you mean that the rotation data constantly changing in one direction?
If so, and you are using a wired tracker, then please try disconnecting and reconnecting the antilatency tracker's cable. Please write back if this solves the drifting or not when the drifting is happening.

Warmest regard,

Thank you very much for your reply!

The data drift is constantly changing in one direction, and I'm using wired tracking.

After I disconnect and reconnect the rotation data still keeps changing in one direction

I have sent a connection for you to see:

Thanks!

Hi Vincent,

There has been a very similar issue for one person here: https://my.aximmetry.com/post/1394-antilatency-202132-error

Are you using one Tracker?
Also, your Antilatency Service settings might hold some clues. If you can, please free to share screenshots of the Environment, Placement, and Device Network tabs of the Antilatency Service.

You might want to contact Antilatency, they could have a solution.

Warmest regards,

I had basically the same problem as he did, and had no problems with  2021.3.1

I'm using one tracker wired connection, tried to disconnect and reconnect the usb, but it's not working either.

Hopefully this issue can be fixed for the benefit of more people using antilatency tracking

Thank you very much!

Hi,

Your hardware says that you are using a Wireless radio socket and not a wired USB socket:

(I don't know how this is possible, probably you want to contact Antilatency about this)

Note that in the screenshot, you selected the receiver/socket of the tracker. And the actual tracker is this:

Also, you can update the device's firmware using this button, but that might not be a good idea in your situation:

Warmest regards,

Oh, I'm sorry.

I'm using Wireless radio socket, but I'm using USB to connect

I tried to upgrade all versions of the device's firmware

Then I switched back to 2021.3.1 and it works again

I'm wondering if the Wireless radio socket and the wired USB socket are not matched properly? They can both be connected to usb to collect data from the tracker

Hi,

If you have a Wired USB Socket, you should try using only that and see if the drifting still happens.
Also, you could try removing the alt and reinserting it again if that helps (to restart the system). And if using only the wireless connection helps.

Note that since 2021.4.1 we are using newer antilatency SDK (3.4.0). When switching back to 2021.3.1, you are also switching back to using Antilatency's older SDK.

Warmest regards,

I just bought a USB socket and tested version 4.1

Found that it still drifts

I recorded a video you can see

Hi,

Now all 3 rotations are quite visibly drifting.
You have the same firmware and hardware versions as in our setup and we don't experience anything like your problem.
I suggest again, to contact Antilatency support. They even have an official Discord server with support.

Also, this tool might help you to find the source of the problem: https://developers.antilatency.com/Internal/Alt_Debug_en.html

Warmest regards,

Hi,

Did you find the sollution to the drifting problem? I am experiencing the same issue with the similar setup.

Thanks

Hi,

For anybody reading this in the future and experiencing similar issues.
Make sure that you placed the floor tiles correctly.
Pay attention to the power connection scheme provided by the antilatency service app and on this page: https://antilatency.com/getting-started/latest/area#content 

Warmest regards,

I am experiencing the same issue with the similar setup.

Any progress?

Antilatency Demo App_Windows with the same hardware working ok.

Thank you

Hi Wicherdt,

Follow closely the antilatency setup guide and make sure your tiles are correctly placed. Like the reference bars should face in the right direction. The direction of the bar is determined by the position of 2 markers close to each other. Parallel bars should face the same direction. https://antilatency.com/getting-started/latest/area#content
Also, you can contact Antilatency support for further guidance.

To my understanding, it would be hard to notice the rotation drifting in the Antilatency Demo App_Windows as it doesn't write out the rotation values.

Warmest regards,

Hi,

thank you.

It was setup problem, if alt work in only gyroscope mode (without IR markers) drifting in one direction.

Now working OK :)
