Wireless communication system, and wireless communication device and control method for establishing a one-to-one relationship between wireless communication devices
First Claim
1. A wireless communication device comprising:
- a wireless communicator adapted to communicate wirelessly; and
a detector adapted to detect an instruction to start a process for setting a communication parameter;
wherein, in response to the detector detecting the instruction, the wireless communication device communicates, if another wireless communication device at which another instruction to start the process for setting the communication parameter has been made is detected, the communication parameter with the detected other wireless communication device using the wireless communicator, disconnects a communication with the detected other wireless communication device in a case that the communication for setting the communication parameter is completed, and sets, into the wireless transmitter, the communication parameter communicated with the other detected wireless communication device, andwherein, if a plurality of other wireless communication devices at which a plurality of other instructions to start the process for setting the communication parameter has been made is detected, the process for setting the communication parameter is aborted as a failure.

Abstract
This invention has as its object to set a one-to-one relationship upon establishing a wireless communication channel between a wireless communication device on the information transmitting side and a wireless communication device that receives and processes the information even in an environment including a plurality of wireless communication devices, and to assure simple user'"'"'s operations at least until the communication channel is established. To this end, when the user inputs a wireless communication channel establishment instruction to both a digital camera and printer having wireless communication functions, these devices execute wireless communication establishment processes within an allowable time period which is specified by a time set in a timer and a retry count. When the devices can seize each other within that time period, the communication channel is established. After that, the digital camera sends a sensed image to the printer, which prints the sensed image.
