Abstract
The communication apparatus is equipped with a first communication interface for executing communication based on a first communication method, and a second communication interface for executing communication based on a second communication method different from the first communication method. The communication apparatus sets ID information for identifying device executing communication by the first communication method, for device which executes communication with the second communication interface. In this manner plural device supporting different communication methods can be recognized as device belonging to a same communication system.
Claims16
