A technique for controlling an electronic device thereof is provided. The technique includes, in response to an attachment device being selected by an external device from a list of attachment devices, receiving and storing mapping information in which data configured in a first communication format and data configured in a second communication format in relation to one function of the electronic device to which the attachment device is attached are mapped. In addition, in response to the data configured in the first communication format being received from an external device which is communicably connected with the attachment device, the data configured in the second communication format corresponding to the data configured in the first communication format based on the mapping information is acquired, and the data configured in the second communication format to the electronic device to control the one function of the electronic device to be performed is transmitted.
