Terminal device and non-transitory computer-readable recording medium storing computer readable instructions for terminal device

A terminal device comprising:

• a wireless interface configured to execute a wireless communication in conformity with either of a first communication scheme of Wi-Fi standard and a second communication scheme of the Wi-Fi standard, the first communication scheme being for executing a wireless communication with a communication device via an access point, and the second communication scheme being for executing a wireless communication with the communication device not via the access point;
• a controller configured to:
• obtain a public key of the communication device;
• send a second request signal to the communication device via the wireless interface;
• in response to the second request signal being sent to the communication device, execute a second-type communication in conformity with the second communication scheme with the communication device via the wireless interface, the second-type communication including communicating second connection information with the communication device, and the second connection information being for establishing a second wireless connection between the terminal device and the communication device;
• in a case where an establishment of the second wireless connection has been failed;
• send a first request signal being different from the second request signal to the communication device via the wireless interface, the first request signal being a signal in which the public key is used;
• and
• in response to the first request signal being sent to the communication device, execute a first-type communication in conformity with the first communication scheme with the communication device via the wireless interface, the first-type communication including sending first connection information to the communication device, and the first connection information being for establishing a first wireless connection between the communication device and the access point.

A non-transitory computer-readable recording medium storing computer readable instructions for a terminal device:

• the terminal device comprising:
• a wireless interface configured to execute a wireless communication in conformity with either of a first communication scheme of Wi-Fi standard and a second communication scheme of the Wi-Fi standard, the first communication scheme being for executing a wireless communication with a communication device via an access point, and the second communication scheme being for executing a wireless communication with the communication device not via the access point;
• and
• a processor,
• wherein the computer-readable instructions, when executed by the processor, cause the terminal device to:
• obtain a public key of the communication device;
• send a first request signal in which the public key is used to the communication device via the wireless interface;
• in response to the first request signal being sent to the communication device, execute a first-type communication in conformity with the first communication scheme with the communication device via the wireless interface, the first-type communication including sending first connection information to the communication device, and the first connection information being for establishing a first wireless connection between the communication device and the access point;
• and
• in a case where an establishment of the first wireless connection has been failed:
• send a second request signal different from the first request signal to the communication device via the wireless interface;
• in response to the second request signal being sent to the communication device, execute a second-type communication in conformity with the second communication scheme with the communication device via the wireless interface, the second-type communication including communicating second connection information with the communication device, and the second connection information being for establishing a second wireless connection between the terminal device and the communication device;
• and
• after the second-type communication is executed with the communication device, establish the second wireless connection between the terminal device and the communication device via the wireless interface by using the second connection information.
