Aerosol-generating device with means for identifying a type of an aerosol-generating article being used with the device

An aerosol-generating device for alternative use with at least a first type and a second type of inductively heatable aerosol-generating articles comprising a susceptor arrangement, the aerosol-generating device comprising:

• a receptacle configured to removably receive at least a portion of an aerosol-generating article from among the first type or the second type of aerosol-generating articles;
• an inductive heating arrangement configured to generate an alternating magnetic field for inductively heating the susceptor arrangement of the aerosol-generating article when the aerosol-generating article is received by the receptacle;
• and
• a controller operatively connected to the inductive heating arrangement and being configured to:
• determine a first value and a second value of an electrical property of the susceptor arrangement of the aerosol-generating article, the electrical property being reached during heating of the susceptor arrangement in use of the device when the aerosol-generating article is received by the receptacle,
• determine the difference between the first value and the second value, and
• identify an article type of the aerosol-generating article received by the receptacle based on the determined difference.
