Communication Apparatus

A communication apparatus comprising:

• a first interface configured to execute a wireless communication;
• a computer;
• and
• a memory that stores computer-readable instructions, wherein the computer-readable instructions, when executed by the computer, cause the communication apparatus to perform:
• in a case where an operation state of the communication apparatus is a second state which is different from a first state, determining a termination timing of a maintenance period for maintaining the operation state of the communication apparatus in the second state;
• when the termination timing of the maintenance period arrives, changing the operation state of the communication apparatus from the second state into the first state;
• in a case where a first wireless network to which both the communication apparatus and a particular external apparatus belong is formed before the termination timing of the maintenance period arrives, executing a wireless communication of target data with the particular external apparatus via the first interface by using the first wireless network;
• detecting a predetermined instruction;
• and
• when the predetermined instruction is detected before the termination timing of the maintenance period arrives, extending the termination timing of the maintenance period so as to determine a new termination timing of the maintenance period.

A non-transitory computer-readable medium storing computer-readable instructions for a communication apparatus, wherein the computer-readable instructions, when executed by a computer of the communication apparatus, cause the communication apparatus to perform:

• in a case where an operation state of the communication apparatus is a parent state and a number of child apparatuses is zero, determining a termination timing of a maintenance period for maintaining the operation state of the communication apparatus in the parent state under a situation where the number of child apparatuses is zero, the parent state being for operating as a parent station of a first wireless network for executing a wireless communication via a first interface of the communication apparatus, the child apparatus being an apparatus which is participating in the first wireless network as a child station;
• when the termination timing of the maintenance period arrives, causing the first wireless network to disappear by changing the operation state of the communication apparatus from the parent state into a non-belonging state in which the communication apparatus is not belonging to a wireless network;
• in a case where a particular external apparatus participates in the first wireless network as the child station before the termination timing of the maintenance period arrives, executing a wireless communication of target data with the particular external apparatus via the first interface by using the first wireless network;
• detecting a predetermined instruction;
• and
• when the predetermined instruction is detected before the termination timing of the maintenance period arrives, extending the termination timing of the maintenance period so as to determine a new termination timing of the maintenance period.
