Odd registerProfile behavior - VivoActive 3 Music

I have coded a Datafield that registers the same thingy52's service and chars. For some oddly reason, when I run the datafield on the simulator, everything works perfectly. It registers the profile, scans after that, etc...

On the other hand, when I run the prg file on my Vivoactive 3 Music, it does not work and gets stuck at registering the profile. The odd thing is that is never breaks/crashes, but the datafield gets stuck at this registerProfile function. I have tried multiple adjustments, adding a callback to verify the registerProfiles function completely registers before it keeps moving forward, but no luck. No logs/crashes...the datafield just gets stuck there on the Vivoactive 3 Music. I worry there is an internal device related bug, or some sort of timing/resources issue with the ble stack.

I can successfully run this on the Simulator under any device listed there.

Any ideas? Anyone experiencing something similar to this?

With the thiny52, if nothing is connected to it, it will go to sleep after about 3 minutes, and if the background is running every 5 minutes, could it be asleep? The led will turn off when it sleeps.

Do you unpair before you exit the background? If not, it might think it's been disconnected and not advertise, so when scanning, it's not seen..

Here's a sample I did 5+ years back with a watch face that has a background service that gets data from a thingy52. Does it work for you?
