New nearby Interaction SDK 3.1 QANI does work reliably

We got a bunch of new DWM3001CDK boards. We program them with the firmware we have been using from the last SDK and they don’t work with our app, Qorvo’s NI app nor NXP’s Trimension NI app. All of these work with the old firmware.

We would migrate to the new SDK except the new Qorvo nearby Interaction app does reliably get the unique BLE device name. Most of the time the device displays as “unknown”. Only occasionally, does it appear as “DWM3001CDK ”. We need unique anchor names to do trilateration.
Has anyone else run into this problem and possibly have a fix?
