Tool/software: Code Composer Studio

Hello,

We're currently using 3.20.00.68 SDK on our LAUNCHXL-CC26x2R development boards to test the RTLS projects.

For some reason the angles on antenna array 2 is giving wrong values, as shown in the picture below:

Is there any fix for this issue? I've already tried the following:

Reinstall CCStudio v9.1
Reinstall 3.20.00.68 SDK
Used the original rtls_example.py
Used Uniflash to completely wipe everything on all boards used (passives, master, and slaves)
Tried using a different computer (Windows and Mac)
Capacitor is already on the correct spot for each passive
Connector from antenna array to dev board is properly connected

The same issues are present on ALL passive devices.

Thank you,

Stefano

Hi Stefano,

I will have a look to your issue on my side. I'll be back to you before the end of next week. In the meantime, I would like to point you to the following thread where I discussed angle compensation with an other user.

Let me know if this work around can help you and if you have further results.

Kind regards,

Stefano,

Have you tried the angle compensation as described in the thread I linked? What are your latest results?

Thanks and regards,

Hi Clément,

I have used the code for an offset on the angles and it works fine. However, we really wanted to get the raw angles fixed instead of applying the offset.

At this time, we've actually reverted to using the 1 antenna array only. Perhaps this is a hardware problem, instead of a software issue?

Thank you,

Stefano

Hi Stefano,

You can apply the same kind of correction to modify the "raw angles" computation instead :)
