Abstract
A communication apparatus including a near field wireless communication unit which holds communication information regarding a communication sets a communication mode to be used for a wireless communication unit supporting a longer field wireless communication than a wireless communication using a near field wireless communication unit in accordance with write information written from an external apparatus to the near field wireless communication unit.
Claims19
A communication apparatus comprising:
- a central processing unit and memory that stores instructions, wherein when instructions are executed by the central processing unit, the central processing unit controls,
- a first wireless communication unit having a memory, the first wireless communication unit configured to
- communicate with an external communication apparatus by near field wireless communication;
- store, in the memory, first information for establishing longer field wireless communication having a communication range longer than a range of the near field wireless communication and which is read by the external communication apparatus;
- and
- store, in the memory, second information for activating an access point included in the communication apparatus, wherein the second information is stored to the memory of the first wireless communication unit by changing the stored first information to the second information by the external apparatus;
- a second wireless communication unit configured to communicate with the external apparatus which read the first information by the longer field wireless communication if the access point is activated;
- a setting unit configured to activate the access point included in the communication apparatus when the first information stored in the memory is changed to the second information by the external apparatus;
- and
- an update unit configured to update the memory of the first wireless communication unit from a state where the second information is stored in the memory of the first wireless communication unit back to a state where the first information, which had been changed to the second information, is stored in the memory of the first wireless communication unit.
A control method executed by a communication apparatus having a first wireless communication unit configured to communicate with an external communication apparatus by near fired wireless communication, which stores, in a memory, first information for establishing a longer field wireless communication having a communication range longer than a range of the near field wireless communication and which is read by the external communication apparatus, and which stores, in the memory second information for activating an access point included in the communication apparatus, wherein the second information is stored in the memory of the first wireless communication unit by changing the stored first information to the second information by the external apparatus, the method comprising:
- activating an access point included in the communication apparatus when the first information stored in the memory is changed to the second information by the external apparatus;
- updating the memory of the first wireless communication unit from a state where the second information is stored in the memory of the first wireless communication unit back to a state where the first information, which had been changed to the second information, is written back into the memory of the first wireless communication unit;
- and
- implementing the longer field wireless communication with the external apparatus which read the first information if the access point is activated.
A non-transitory storage medium storing instructions that, when executed by a processor, executes a control method for a communication apparatus having a first wireless communication unit configured to communicate with an external communication apparatus by near fired wireless communication, which stores, in a memory, first information for establishing a longer field wireless communication having a communication range longer than a range of the near field wireless communication and which is read by the external communication apparatus, and which stores, in the memory second information for activating an access point included in the communication apparatus, wherein the second information is stored in the memory of the first wireless communication unit by changing the stored first information to the second information by the external apparatus
- activating an access point included in the communication apparatus when the first information stored in the memory is changed to the second information by the external apparatus;
- updating the memory of the first wireless communication unit from a state where the second information is stored in the memory of the first wireless communication unit back to a state where the first information, which had been changed to the second information, is written back into the memory of the first wireless communication unit;
- and
- implementing the longer field wireless communication with the external apparatus which read the first information if the access point is activated.
