Application: Communication device and non-transitory computer-readable recording medium storing computer-readable instructions for communication device (Patent ID: US20230276241A1)
The patent filed by Brother Industries Ltd. describes a communication device that can execute different processes and shift its state accordingly. The first process is based on a Device Provisioning Protocol (DPP) scheme, while the second process uses a different wireless connection scheme. The communication device can transition from a first state to a second state after sending an authentication response to an external device and before establishing a wireless connection with another external device.
The first claim specifies that the communication device includes a controller that can execute the first and second processes and shift the device's state. The first process involves receiving an authentication request from a first external device, sending an authentication response, and establishing a wireless connection with a second external device. The controller shifts the device's state from the first state to the second state after sending the authentication response but before establishing the wireless connection.
The second claim adds that the first process includes receiving a confirmation signal from the first external device after sending the authentication response. The controller shifts the device's state from the first state to the second state after receiving the confirmation signal but before establishing the wireless connection.
The third claim further expands the first process by including sending a request signal to the first external device to obtain first wireless connection information. The controller establishes the wireless connection with the second external device using the received information and shifts the device's state from the first state to the second state after sending the authentication response but before sending the request signal.
The fourth claim introduces the second process, which involves receiving a connection request from a third external device, establishing a second wireless connection, receiving second wireless connection information, and establishing a third wireless connection with the second external device. The controller shifts the device's state from the first state to a third state after receiving the connection request but before establishing the third wireless connection.
The remaining claims describe additional features such as shifting the device's state back to the first state if the first wireless connection fails, using a code image to represent the public key, outputting the code image, shifting the state to a fifth or sixth state after a predetermined time period, and a computer-readable recording medium storing instructions for the communication device.
In summary, the patent describes a communication device that can execute different processes, shift its state based on the execution of these processes, and establish wireless connections with external devices using different schemes.
