A communication device may execute a first process according to a Device Provisioning Protocol (DPP) scheme, execute a second process according to a first wireless connection scheme different from the DPP scheme; and shift a state of the communication device. The first process may include, under a situation where the state of the communication is a first state, receiving an authentication request from a first external device, sending an authentication response to the first external device, and establishing a first wireless connection with a second external device. A communication device may be configured to shift the state of the communication device from the first state to a second state after the authentication response has been sent to the first external device and before the first wireless connection is established with the second external device.

Communication device and non-transitory computer-readable recording medium storing computer-readable instructions for communication device

A communication device may receive a specific signal from a first external device; display a first instruction screen; in a case where it is instructed that the target process is to be executed in a situation where the first instruction screen is displayed, send a public key to the first external device, wherein in a case where it is not instructed that the target process is to be executed in the situation where the first instruction screen is displayed, the public key is not sent; after the public key has been sent to the first external device, receive an authentication request from the first external device; send an authentication response to the first external device; receive connection information from the first external device; and establish, by using the connection information, a wireless connection between the communication device and a second external device.

A communication device may execute an output control process for externally outputting output information obtained by using a public key, receive an authentication request in which the public key is used from a terminal device, send an authentication response to the terminal device, receive N pieces of wireless setting information from the terminal device, send, by using each of the N pieces of wireless setting information, a confirm signal to an access point corresponding to each of the N pieces of wireless setting information, receive a response signal in response to sending the confirm signal from each of M access points among N access points, select a target access point from among the M access points, and establish a wireless connection with the target access point.

Communication device and non-transitory computer-readable medium storing computer-readable instructions for communication device

A communication device may: comprise an output unit configured to output first information obtained by using a first public key in a memory in a case where a predetermined instruction is inputted to the communication device; after the first information has been outputted, receive an authentication request in which the first public key is used from a terminal device; send an authentication response to the terminal device; establish a wireless connection between the communication device and an external device; and in a case where a predetermined condition is satisfied after the first information has been outputted, create a second public key different from the first public key and store the second public key in the memory. In a case where the predetermined instruction is inputted to the communication device again, the output unit may be configured to output second information obtained by using the second public key in the memory.

Communication device configured to establish wireless connection between communication device and external device, non-transitory computer-readable medium storing computer-readable instructions for such communication device and method executed by such communication device

A first communication device may execute an output control process of externally outputting output information, the output information obtained using a public key of the first communication device, receive an authentication request from a second communication device that has obtained the public key, send a first authentication response to the second communication device via a wireless interface in a case where it is determined that a wireless connection has been established between the first communication device and a first access point, the first authentication response including first role information indicating that the first communication device is to serve a first role which is a role of sending first wireless setting information to the second communication device, and send the first wireless setting information to the second communication device.

First communication device and non-transitory computer-readable medium storing computer-readable instructions for first communication device

A first terminal device may send address information which is an IP address of the first terminal device to the first communication device by using a communication network, and send a public key of the first terminal device to the first communication device by using the communication network. The first terminal device may receive a first authentication request in which the first public key is used from the first communication device by using the communication network. The first authentication request may be sent with the address information as a destination. The terminal device may send a first authentication response to the first communication device by using the communication network and send connection information to the first communication device by using the communication network. The connection information may be used by the first communication device to establish a first wireless connection between the first communication device and an external device.

Non-transitory computer-readable recording medium storing computer-readable instructions for terminal device and communication device

A communication device may receive a specific signal from a first external device; after the specific signal has been received from the first external device, cause an output unit of the communication device to output specific information obtained by using a public key; after the specific information has been outputted, receive an authentication request in which the public key is used from the first external device; in a case where the authentication request is received from the first external device, send an authentication response to the first external device; after the authentication response has been sent to the first external device, receive connection information from the first external device; and in a case where the connection information is received from the first external device, establish, by using the connection information, a wireless connection between the communication device and a second external device.

Communication device

A communication device may display an instruction screen in a case where a first wireless connection is established between the communication device and a first external device; in a case where it is instructed that a target process is to be executed in a situation where the instruction screen is displayed, supply, to the first wireless interface, first instruction information; after the public key has been sent to the first external device, receive an authentication request from the first external device; send an authentication response to the first external device; receive connection information from the first external device; and in a case where the connection information is received from the first external device, establish, by using the connection information, the second wireless connection between the communication device and a second external device.

A communication device may establish a first wireless connection with a first external device, and receive target wireless setting information from the first external device by using the first wireless connection, the target wireless setting information being for participating as a child station in a target wireless network formed by a target access point different from the first external device. The communication device may control a display unit to display a predetermined screen for accepting a trigger operation, the trigger operation being a trigger of participation in the target wireless network, and establish a target wireless connection with the target access point by using the target wireless setting information so as to participate as the child station in the target wireless network, in a case where the trigger operation is accepted after the predetermined screen has been displayed.
