  • Patent number: 10742247
    Abstract: A short-range wireless communication apparatus is disclosed. The short-range wireless communication apparatus comprises: multiple connection devices and a control device. The connection devices are capable of simultaneously connecting multiple communication interfaces to a communication counterparty apparatus to enable sound data transfer. When the control device determines that, in cases where the communication interfaces are communicably connected, there arises a request to start outputting the sound data transferred by one of the communication interfaces, the control device disconnects another one of the communication interfaces while keeping the one of the communication interfaces connected and causes a sound data output device to output the sound data transferred from the communication counterparty apparatus by the one of the communication interfaces.

  • Patent number: 9398139
    Abstract: An onboard apparatus uses two modes to transfer audio data from a mobile phone. A first mode transfers and outputs audio data stored in the mobile phone. The first mode communicates control data according to a control data transfer protocol and transfers and outputs audio data according to an audio data transfer protocol. The second mode permits the mobile phone to successively buffer audio data stored in a server on a communication network and to concurrently transfer and output the buffered data. The second mode replaces the control data transfer protocol with a specific data communication protocol. The second mode communicates control data according to the specific data communication protocol and transfers and outputs audio data according to the audio data transfer protocol. The second mode can communicate any commands and data using the specific data communication protocol regardless of commands specified in the control data transfer protocol.

  • Patent number: 9026045
    Abstract: 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.

  • Patent number: 8914077
    Abstract: 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.

  • Patent number: 8909302
    Abstract: 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.

  • Patent number: 8867998
    Abstract: A short range wireless communication device includes: a connection unit connectable with an external connection unit according to multiple data communication protocols defining data communication via a short range communication line covering a communication band; and a control unit that controls connection/disconnection of protocols. The protocols include high and low priority data communication protocols corresponding to high and low priority parts of the communication band, respectively. When a request for concurrently executing data communications under protocols is issued, the control unit preserves the high priority part of the communication band in priority to the low priority part of the communication band to execute high priority data communication under the high priority data communication protocol in priority to low priority data communication under the low priority data communication protocol.

  • Patent number: 8792827
    Abstract: A short range wireless communication apparatus includes: a connection device that connects with an external apparatus via a short range wireless communication line according to a data communication protocol for defining data communication, wherein the external apparatus switches to a normal mode from a power-saving mode under a condition that the external apparatus receives a power-saving mode release signal from the short range wireless communication apparatus while the external apparatus operates in the power-saving mode; a transmission device that transmits the power-saving mode release signal to the external apparatus; and a control device that controls the transmission device to transmit the power-saving mode release signal to the external apparatus when the control device determines that the connection device connects with the external apparatus according to the data communication protocol.

  • Patent number: 8761673
    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.

  • Patent number: 8731473
    Abstract: Multiple profiles are concurrently connected between an in-vehicle apparatus and a mobile phone. A streaming function is performed based on a related profile of the multiple profiles. A dial-up networking profile connection request occurs but is rejected to make connection unsuccessful. In such a case, the in-vehicle apparatus disconnects the related profile out of the currently connected multiple profiles or interrupts the streaming function based on the related profile. The in-vehicle apparatus then performs a re-connection of the dial-up networking profile with the mobile phone because the cause of rejecting the dial-up networking profile connection request is removed.
