Solution Overview
Problem
In existing wireless communication systems, there is a possibility that a second printer may fail to receive network wireless settings from a first printer, especially when establishing connections with different apparatuses, leading to incomplete or incorrect setting information transfer.
Innovation Solution
A communication apparatus is designed to operate in specific modes to determine and establish connections with target devices, using a processor and memory to store and manage setting information, allowing it to correctly receive and store setting information from a target apparatus by distinguishing between different types of connection requests and establishing appropriate wireless connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication apparatus establishes a wireless connection with any external apparatus, then the apparatus can communicate with external devices, but the setting information may be received from the wrong apparatus leading to incorrect settings
Solution Approach 1:
The communication apparatus stores the MAC address of the target apparatus in advance in the setting area before receiving setting information. This preliminary identification ensures that when setting information is received, the apparatus can verify it comes from the correct target apparatus, preventing incorrect settings while maintaining connection capability.
Solution Approach 2:
The communication apparatus checks the MAC address of the apparatus sending setting information against the stored target apparatus MAC address. This feedback mechanism verifies the source of setting information and prevents the apparatus from accepting settings from unauthorized sources, ensuring reliability while allowing versatile connections.
2Reliability
If the communication apparatus operates in setting mode to receive setting information, then the apparatus can store correct setting information, but may fail to establish connection with the target apparatus if connection requests are not properly distinguished
Solution Approach 1:
Before receiving setting information, the communication apparatus preliminarily stores the MAC address of the target apparatus in the setting area. This preparation ensures that when connection requests arrive, the apparatus can immediately identify the correct target and establish connections without complex verification processes, maintaining ease of operation while ensuring reliability.
Solution Approach 2:
The communication apparatus automatically uses the stored MAC address to identify and connect with the target apparatus without requiring manual intervention or complex user input. The system self-verifies the connection target using the pre-stored information, simplifying the user experience while ensuring accurate connection establishment.

AI summary
A communication apparatus may determine whether a first external apparatus is a target apparatus by referring content of a predetermined area included in a first connection request, in a case where the first connection request is received from the first external apparatus via a wireless interface, under a state where the communication apparatus operates in a first operation mode, and establishes a first wireless communication with the first external apparatus in a case where it is determined that the first external apparatus is the target apparatus. A wireless communication with the first external apparatus may not be established in a case where it is determined that the first external apparatus is not the target apparatus. The communication apparatus may store setting information in a setting area in a memory in a case where the setting information is received from the first external apparatus by using the first wireless connection.
