1. A communication apparatus comprising:
a wireless interface configured to execute a wireless communication according to Device Provisioning Protocol (DPP) scheme of Wi-Fi standard;
a controller;
a memory configured to store a computer-readable program; and
a housing to which a seal is attached, the seal including a code image that is generated by encoding a character string, the character string being described in accordance with Bootstrapping Information Format and including a public key of the communication apparatus and specific information, the specific information being used for enabling a first terminal to execute a display process for displaying an operation screen of the communication apparatus, the operation screen indicating a changing operation for changing a state of the communication apparatus from a first state in which a wireless communication according to the DPP scheme is not to be executed to a second state in which the wireless communication according to the DPP scheme is to be executed;
wherein the computer-readable program, when executed by the controller, causes the communication apparatus to:
receive the changing operation for changing the state of the communication apparatus from the first state to the second state after the first terminal obtains the character string by decoding the code image of the seal;
in a case where the changing operation is received, establish a wireless communication via the wireless interface with the first terminal according to the DPP scheme in response to the first terminal using the public key included in the character string.
