My test was conducted by changing the pink dice to have a 16 bit UUID using the ASKSampleAccessory app. Afterwards, I ran AccessorySetupKit Picker in the ASKSample app, but Pink dice was not found. We confirmed that Pink dice was searched well in other apps. Does AccessorySetupKit not support 16 bit UUID?

This might require our engineering teams to investigate this issue
We'd greatly appreciate it if you could open a bug report, include crash logs and sample code or models that reproduce the issue, and post the FB number here once you do.

It would be very helpful if you could please go to https://developer.apple.com/bug-reporting/profiles-and-logs/ and follow the instructions for Bluetooth for iOS to install a logging profile on your device. Then reproduce the issue, and follow the instructions at the above link to create a sysdiagnose. And attach that to the Feedback report as well.
