A non-transitory computer-readable recording medium storing computer-readable instructions for a first communication device, wherein
- the first communication device comprising:
- a processor;
- and
- a wireless interface configured to execute wireless communication in conformity with a Wi-Fi standard,
- wherein the computer-readable instructions, when executed by the processor, cause the first communication device to:
- execute an output control process of externally outputting output information, the output information being in conformity with the Wi-Fi standard and obtained using a public key of the first communication device;
- receive, via the wireless interface, an authentication request in which the public key is used from a second communication device that has obtained the public key;
- determine whether a wireless connection has been established between the first communication device and any one of access points;
- in a case where it is determined that a wireless connection has been established between the first communication device and a first access point:
- send a first authentication response to the second communication device via the wireless interface 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, the first wireless setting information being for establishing a first wireless connection between the second communication device and the first access point;
- and
- send the first wireless setting information to the second communication device via the wireless interface after the first authentication response has been sent to the second communication device;
- in a case where it is determined that no wireless connection has been established between the first communication device and any of the access points:
- send a second authentication response to the second communication device via the wireless interface, the second authentication response including second role information indicating that the first communication device is to serve a second role which is different from the first role and is a role of receiving second wireless setting information from the second communication device, the second wireless setting information being for establishing a second wireless connection between the first communication device and a second access point;
- receive the second wireless setting information from the second communication device via the wireless interface after the second authentication response has been sent to the second communication device;
- and
- establish the second wireless connection with the second access point via the wireless interface using the second wireless setting information.
