Abstract

A first communication apparatus may repeat a broadcast transmission of a trigger signal via a second interface, which is a signal to be used by a second communication apparatus as a trigger for sending a wireless connection request to the first communication apparatus. The wireless connection request may be for forming a first wireless network to which both the first communication apparatus and the second communication apparatus belong. The first wireless network may be a network for performing a wireless communication via a first interface. The first communication apparatus may receive the wireless connection request via the first interface from the second communication apparatus which has received the trigger signal, and establish a first wireless connection via the first interface with the second communication apparatus so as to form the first wireless network.

Dependent claims

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

the terminal device comprising:
a Wi-Fi interface configured to perform a wireless communication according to a Wi-Fi scheme;
a Bluetooth interface configured to perform a wireless communication according to a Bluetooth scheme;
a memory;
and
a processor,
wherein the computer-readable instructions, when executed by the processor, causing the terminal device to perform:
receiving a first advertise signal according to the Bluetooth scheme from a printer via the Bluetooth interface, the first advertise signal being a signal of which destination is not specified, the first advertise signal according to the Bluetooth scheme including a first SSID, the first SSID being for Wi-Fi network to which the terminal device and the printer are to belong;
in a case where the first advertise signal including the first SSID is received from the printer without sending any signal via the Bluetooth interface to the printer before receiving the first advertise signal, sending a first wireless connection request to the printer via the Wi-Fi interface;
in response to sending the first wireless connection request to the printer, establishing a first Wi-Fi connection via the Wi-Fi interface with the printer so as to belong to the Wi-Fi network to which both the printer and the terminal device belong;
sending image data via the Wi-Fi interface to the printer by using the Wi-Fi network,
after the first Wi-Fi connection with the printer has been disconnected, receiving a second advertise signal according to the Bluetooth scheme from the printer via the Bluetooth interface, the second advertise signal including a second SSID different from the first SSID, the second SSID being generated by the printer after the first Wi-Fi connection between the terminal device and the printer has been disconnected and before sending of the second advertise signal is started;
in a case where the second advertise signal including the second SSID is received from the printer without sending any signal via the Bluetooth interface to the printer before receiving the first advertise signal, sending a second wireless connection request to the printer via the Wi-Fi interface;
and
in response to sending the second wireless connection request to the printer, establishing a second Wi-Fi connection via the Wi-Fi interface with the printer so as to belong to the Wi-Fi network to which both the printer and the terminal device belong.
