Abstract

A short-range wireless communication apparatus including a connection device and a control device is disclosed. The connection device is capable of connecting a communication protocol to a communication destination device. After transmitting a connection request signal of a first protocol to the communication destination device, the connection device waits for receipt of a response signal. When a request to connect a second protocol is generated while the connection device is waiting for receipt of a response signal, the control device causes the connection device to interrupt waiting for the receipt of the response signal and transmits the connection request signal of the second protocol to the communication destination device.

Claims

1. A short-range wireless communication apparatus comprising:

a own connection device that is capable of connecting a communication protocol including a first communication protocol and a second communication protocol to a communication destination side connection device that, upon receipt of a connection request signal of the communication protocol via a short-range wireless communication line, transmits a connection permission response signal of the communication protocol or a connection rejection response signal of the communication protocol via the short-range wireless communication line in accordance with a user operation; and

a control device that, when determining that a request to connect the second communication protocol is generated while the own connection device is waiting for receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol after transmission of the connection request signal of the first communication protocol from the own connection device to the communication destination side connection device via the short-range wireless communication line,

stops the own connection device from waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol from the communication destination side connection device and

causes the own connection device to transmit the connection request signal of the second communication protocol to the communication destination side connection device via the short-range wireless communication line.

2. The short-range wireless communication apparatus according to claim 1, wherein

when the control device determines that priority level of the second communication protocol is higher than that of the first communication protocol, the control device

stops the own connection device from waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol and

causes the own connection device to transmit the connection request signal of the second communication protocol to the communication destination side connection device via the short-range wireless communication line.

3. The short-range wireless communication apparatus according to claim 2, wherein:

when the control device determines that, after the own connection device stops waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol and transmits the connection request signal of the second communication protocol to the communication destination side connection device via the short-range wireless communication line, the own connection device receives the connection permission response signal of the second communication protocol or the connection rejection response signal of the second communication protocol, the control device

causes the own connection device to transmit the connection request signal of the first communication protocol to the communication destination side connection device via the short-range wireless communication line.

4. The short-range wireless communication apparatus according to claim 2, wherein

when the control device determines that, after the own connection device stops waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol and transmits the connection request signal of the second communication protocol to the communication destination side connection device via the short-range wireless communication line, a connection process of connecting the second communication protocol is successfully or abnormally ended, the control device

causes the own connection device to transmit the connection request signal of the first communication protocol to the communication destination side connection device via the short-range wireless communication line.

5. The short-range wireless communication apparatus according to claim 2, wherein:

when the control device determines that, after the own connection device stops waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol and transmits the connection request signal of the second communication protocol to the communication destination side connection device via the short-range wireless communication line, the own connection device receives the connection permission response signal of the second communication protocol or the connection rejection response signal of the second communication protocol, the control device

causes the own connection device to resume waiting for receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol.

6. The short-range wireless communication apparatus according to claim 1, wherein:

when the control device determines that priority level of the second communication protocol is lower than that of the first communication protocol, the control device

causes the own connection device to continue waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol from the communication destination side connection device without stopping the own connection device from waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol from the communication destination side connection device.

7. The short-range wireless communication apparatus according to claim 6, wherein:

when the control device determines that, after the own connection device continues, without stopping, waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol from the communication destination side connection device, the own connection device receives the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol from the communication destination side connection device, the control device

causes the own connection device to transmit the connection request signal of the second communication protocol to the communication destination side connection device via the short-range wireless communication line.

8. The short-range wireless communication apparatus according to claim 1, wherein:

when the control device determines that, for a predetermined time period, the own connection device continues waiting for the receipt of the connection permission response signal of the first communication protocol or the connection rejection response signal of the first communication protocol from the communication destination side connection device due to transmission of the connection request signal of the first communication protocol from the own connection device to the communication destination side connection device via the short-range communication line and that the predetermined time period has elapsed without the own connection device'"'"'s receipt of the connection permission response signal of the first communication protocol nor the connection rejection response signal of the first communication protocol from the communication destination side connection device, the control device causes a notification device to output a notification about the user operation.
