BlueZ bluetooth qualification

Hi,

My company wants to release a product where the BlueZ daemons are running as a host subsystem (both bluetoothd and bluetooth-meshd). So the product needs to be qualified.
I have looked on the web-page and searched in the archive of this mailing list but didn't really find any up-to-date information about this. So I wanted to ask if you have some new information that could help.
What are the general guidelines to qualify a product that is using the BlueZ stack? Is there a version that is already qualified that can be referred to? Or is the best way to qualify it ourselves using PTS testing?

Thank you and best regards,
Isak
