Wireless communication devices, systems, and programs perform, via a single antenna: (i) communications in a first wireless communication mode in which processing of searching for other registered devices is repeatedly executed at a predetermined execution interval in order to connect to these other devices, the execution interval being set to a reference interval; and (ii) communications in a second wireless communication mode according to a communication standard other than the first wireless communication mode. The devices, methods, and programs change the execution interval in the first wireless communication mode to a value larger than the reference interval during at least a part of a period during which communication in the second wireless communication mode is being performed or communication in the second wireless communication mode is enabled.

Wireless communication device, wireless communication method and program

A communication unit connects an e-mail data transfer protocol to transfer e-mail data item via near-field wireless communications with an external device. A retrieval unit retrieves the e-mail data item transferred from the external device when the protocol is connected. A storage unit stores the retrieved e-mail data item. A control unit causes the external device to transfer the e-mail data item in each indication unit of the indication device thereby to cause the storage unit to store the retrieved e-mail data item, when the protocol is connected, and even when a user does not implement a browsing operation of an e-mail list. The control unit further causes an indication device to indicate the e-mail list of the stored e-mail data item when the user implements the browsing operation.

Electronic mail data processing device and method for processing electronic mail data

A communication unit connects an e-mail data transfer protocol to transfer e-mail data items with an external device. An e-mail data storage unit stores the e-mail data items transferred from the external device. The control unit does not cause the external device to transfer the e-mail data items when the e-mail data transfer protocol is connected and when a total number of subjects of the e-mail data items and a data content of a latest e-mail data item stored in the external device respectively coincide with a total number of subjects of the e-mail data items and a data content of a latest e-mail data item stored in the e-mail data storage unit, at the time point when the e-mail data transfer protocol is connected between the communication unit and the external device.

An in-vehicle apparatus selects, as a profile connection mode, one connection mode out of a first connection mode and a second connection mode, and performs profile connection using the selected one connection mode. The first connection mode is to transmit a profile connection request signal to a communication partner so as to start a connection procedure; the second connection mode is to wait for reception of a profile connection request signal from the communication partner for a predetermined time so as to start the connection procedure. When the profile connection using the selected one connection mode fails, a connection procedure using the other connection mode that was not selected previously is started. When the profile connection using the other connection mode is successful, upon occurrence of a next profile connection request, the other connection mode is selected as a profile connection mode.

Short range wireless communication apparatus

A control circuit of an the in-vehicle apparatus repeatedly performs a Bluetooth connection operation to connect to both of registered cellular phones and registered portable AV players in such a manner that, if an HFP connection has already been established to a cellular phone prior to an AVP connection to a portable AV player, the control circuit performs one round of AVP connection attempts to all of the registered portable AV players according to a priority order, prior to performing connection attempts to connect other data communication type profile to the cellular phone. By using such a profile connection scheme, the AVP connection attempt will not be delayed until after a connection attempt of the other data communication type profile.

In-vehicle apparatus

When connecting a multi-profile device by Bluetooth, an in-vehicle apparatus performs a MAP connection establishment process in succession to an HFP connection establishment process to have a MAP connection established earlier than a conventional timing, thereby reducing a waiting period before receiving a new message arrival notification from the multi-profile device through the MAP connection.

A subject short-range wireless communication apparatus capable of simultaneously connecting multiple profiles with another short-range wireless communication apparatus acting as a connection counterpart is disclosed. The subject apparatus comprises: a communication disconnection detection device that, in cases where a first profile is connected between the subject apparatus and the another apparatus, detects whether or not the first profile is disconnected due to the subject apparatus' non-acceptance of a connection request of a second profile sent from the another apparatus; and a communication re-connection device that, in response to disconnection of the first profile detected by the communication disconnection detection device, re-connects the first profile with the another apparatus.
