COMMUNICATION APPARATUS, COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a communication apparatus having the same communication card that can simplify a radio communication link estabilishing job when connected to an external device having been connected before even if a host device mounted with the communication card differs. SOLUTION: A log information storage area 111d is provided to a flash ROM 111 of an SD card 13 and stores log information when the SD card 13 is mounted to a host device such as a personal computer 1 and performs radio communication with an external device. Then when another host device such as a PDA 21 performs radio communication with the same external device, the host device downloads the log information from the log information storage area 111d so as to simplify radio link setup.
