Abstract

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.

Claims8

Dependent claims

A communication device comprising:

an instruction unit;
a first wireless interface;
a second wireless interface different from the first 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:
receive a specific signal from a first external device via the first wireless interface;
in a case where the specific signal is received from the first external device and a specific instruction is received via the instruction unit, send a public key for a connection process according to Device Provisioning Protocol (DPP) scheme to the first external device via the first wireless interface,
wherein in a case where the specific signal is received from the first external device and the specific instruction is not received via the instruction unit, the public key is not sent;
and
after the public key has been sent to the first external device, establish, by executing the connection process according to the DPP scheme, a wireless connection between the communication device and a second external device via the second wireless interface.
