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. I think that if we decide to go with dedicated prop for this, it should rather be an array of strings of supported technologies eg [LE, BR/EDR] instead of string for device type. That way we could leave room for extending those easily if needed in the future (eg with AMP ?). -- pozdrawiam Szymon K.
