I don’t like upper-case for values of this type. We have kept them normally all lower-case.

Anyhow, actually you can deduct this information already from existing Class and Appearance values. If Class exists it is BR/EDR and if Appearance exists it is LE. If both exist it is dual-mode device. Only trick part might be that Appearance is optional, but we could just fill it in with some generic value. Would need to look that up.

Regards

Marcel
