Abstract
A communication apparatus includes: a data generating unit that generates write data to be sent to any other communication apparatus at an arbitrary timing; a communication unit that repeatedly sends a read request to the other communication apparatus until the write data is generated and, at the same time, repeatedly receives a read response sent from the other communication apparatus in response to the read request; and a data acquisition unit that acquires read data, which is sent along with the read response by the other communication apparatus, when the read data is generated at an arbitrary timing by the other communication apparatus.
Claims16
A communication apparatus comprising:
- a data generating unit that generates write data to be sent to another communication apparatus and written therein at an arbitrary timing;
- a communication unit that repeatedly sends a read request to the another communication apparatus until the write data is generated and, at the same time, repeatedly receives a read response sent from the another communication apparatus in response to the read request;
- and
- a data acquisition unit that acquires read data, which is sent along with the read response by the another communication apparatus, when the read data is generated at an arbitrary timing by the another communication apparatus.
A communication apparatus, comprising:
- a near field communication unit configured to send a response to a communication terminal in response to a read request from the communication terminal;
- and
- a control unit configured to cause the near field communication unit to send read data with the response when the read data is ready to send,
- wherein the read data is generated in the communication apparatus at an arbitrary timing, and
- wherein the read request is received repeatedly from the communication terminal.
A communication terminal, comprising:
- a near field communication unit configured to send a read request to a communication apparatus;
- and
- a control unit configured to cause the near field communication unit to send the read request repeatedly when write data is not ready to send,
- wherein the write data is generated at an arbitrary timing in the communication terminal.
A communication method comprising:
- causing a near field communication unit to send a response to a communication terminal in response to a read request from the communication terminal;
- and
- causing the near field communication unit to send read data with the response when the read data is ready to send,
- wherein the read data is generated at an arbitrary timing, and
- wherein the read request is received repeatedly from the communication terminal.
A communication method comprising:
- causing a near field communication unit to send a write request to a communication apparatus when write data is ready to send;
- and
- causing the near field communication unit to send a read request repeatedly when the write data is not ready to send,
- wherein the write data is generated at an arbitrary timing in a communication terminal.
