Communication Device and Non-Transitory Computer-Readable Recording Medium Storing Computer-Readable Instructions for Communication Device

A communication device comprising:

• a first wireless interface;
• a second wireless interface;
• a processor;
• and
• a memory storing computer-readable instructions therein, the computer-readable instructions, when executed by the processor, causing the communication device to:
• in a case where a first wireless connection via the first wireless interface is established with a first terminal device, send first authentication information prepared by the communication device to the first terminal device via the first wireless interface by using the first wireless connection;
• after the first authentication information has been sent to the first terminal device, determine whether specific information is received from a second terminal device via the second wireless interface during a predetermined communication being executed with the second terminal device, the specific information being obtained by using the first authentication information, the predetermined communication being for establishing a second wireless connection;
• and
• in a case where it is determined that the specific information is received from the second terminal device, establish the second wireless connection via the second wireless interface with the second terminal device by completing the predetermined communication with the second terminal device,
• wherein in a case where it is determined that the specific information is not received from the second terminal device, the predetermined communication with the second terminal device is canceled.

A non-transitory computer-readable recording medium storing computer-readable instructions for a communication device,

• wherein the computer-readable instructions, when executed by a processor of the communication device, cause the communication device to:
• in a case where a first wireless connection via a first wireless interface of the communication device is established with a first terminal device, receive first identification information for identifying the first terminal device from the first terminal device via the first wireless interface by using the first wireless connection;
• after the first identification information has been received from the first terminal device, receive a connection request for requesting establishment of a wireless connection from a second terminal device via a second wireless interface of the communication device, the connection request including second identification information for identifying the second terminal device;
• in a case where the connection request is received from the second terminal device, determine whether the first identification information is identical to the second identification information;
• and
• in a case where it is determined that the first identification information is identical to the second identification information, establish a second wireless connection via the second wireless interface with the second terminal device by sending a predetermined response to the second terminal device via the second wireless interface,
• wherein in a case where it is determined that the first identification information is not identical to the second identification information, the predetermined response is not sent to the second terminal device that is different from the first terminal device.
