Abstract
An accessory is attachable to, detachable from, and communicable with an electronic apparatus. The accessory includes an accessory processing unit configured to make a communication request to the electronic apparatus and to transmit information about a factor of the communication request. The accessory processing unit notifies the electronic apparatus by a first communication method of information corresponding to a used communication method for communicating the information about the factor, among the first communication method and a second communication method different from the first communication method.
Claims22
An accessory attachable to, detachable from, and capable of communicating with an electronic apparatus by a first communication method and by a second communication method different from the first communication method, the accessory comprising:
- at least one processor;
- and at least one memory coupled to the at least one processor storing instructions that, when executed by the at least one processor, cause the at least one processor to function as an accessory processing unit configured to:
- inform the electronic apparatus, by the first communication method, on a factor acquiring method among the first communication method and the second communication method, in response to the accessory being attached to the electronic apparatus;
- make a communication request to the electronic apparatus;
- transmit information about a factor of the communication request to the electronic apparatus using the factor acquiring method informed to the electronic apparatus, in response to the communication request, and wherein the factor acquiring method is for communicating information about the factor of the communication request from the accessory to the electronic apparatus, and wherein the information is about the factor of the communication request associated with an event which causes the accessory to communicate with the electronic apparatus.
An electronic apparatus which an accessory is attachable to, detachable from, and capable of communicating with the electronic apparatus by a first communication method and by a second communication method different from the first communication method, the electronic apparatus comprising:
- at least one processor;
- and at least one memory coupled to the at least one processor storing instructions that, when executed by the at least one processor, cause the at least one processor to function as a first processing unit configured to receive a factor acquiring method among the first communication method and the second communication method from the accessory, by the first communication method, in response to the accessory being attached to the electronic apparatus, a communication request from the accessory, and information corresponding to the factor acquiring method for communicating information about a factor of the communication request from the accessory using the factor acquiring method informed to the electronic apparatus, in response to the communication request, wherein the factor acquiring method is for communicating information about the factor of the communication request from the accessory to the electronic apparatus, and wherein the information is about the factor of the communication request associated with an event which causes the accessory to communicate with the electronic apparatus.
A control method of an accessory attachable to, detachable from, and capable of communicating with an electronic apparatus by a first communication method and by a second communication method different from the first communication method, the control method comprising the steps of:
- informing the electronic apparatus, by the first communication method, on a factor acquiring method among the first communication method and the second communication method, in response to the accessory being attached to the electronic apparatus;
- making a communication request to the electronic apparatus;
- and transmitting information about a factor of the communication request to the electronic apparatus using the factor acquiring method informed to the electronic apparatus, in response to the communication request;
- wherein the factor acquiring method is for communicating information about the factor of the communication request from the accessory to the electronic apparatus, and wherein the information is about the factor of the communication request associated with an event which causes the accessory to communicate with the electronic apparatus.
A control method of an electronic apparatus, which an accessory is attachable to, detachable from, and capable of communicating with the electronic apparatus by a first communication method and by a second communication method different from the first communication method, the control method comprising the steps of:
- receiving a factor acquiring method among the first communication method and the second communication method from the accessory, by the first communication method, in response to the accessory being attached to the electronic apparatus, receiving a communication request from the accessory;
- and receiving information corresponding to the factor acquiring method for communicating information about a factor of the communication request from the accessory using the factor acquiring method informed to the electronic apparatus, in response to the communication request, wherein the factor acquiring method is for communicating information about the factor of the communication request from the accessory to the electronic apparatus, and wherein the information is about the factor of the communication request associated with an event which causes the accessory to communicate with the electronic apparatus.
