    Abstract: Synchronized media streaming in a device chain including first, second and third Bluetooth media device having a controller and time synchronization algorithm. The first device formats a first media packet including received media data, second device address, and synchronization information including packet start time including a delay time and cumulative clock drift counted thus far. The second device receives the first packet and formats a second packet including the media data, third device address, updated synchronization information including the second packet's play start time, local clock time, clock drift, and a cumulative clock drift counted thus far. The second device transmits the second packet to the third device. The synchronization algorithms begin synchronized playing of the media data including the first device playing after the delay time, second device playing after the first packet's play start time, and the third device playing after the second packet's play start time.

    Abstract: A Bluetooth (BT) device includes a host processor and a BT controller coupled by a Host Controller Interface (HCI) including a Host Controller Transport Layer and a HCI Driver. The host processor implements an applications layer and includes HCI firmware for communicating via the Host Controller Transport Layer with the BT controller. The BT controller includes a processor coupled to a memory and to a transceiver, and a RF driver. The HCI firmware also includes HCI command code for a user to define a topology of the BT network including configuring the BT device in a current chain including a plurality of BT devices including configuring from which BT device it receives data from and which BT device it forwards data to. For communicating data across the BT network the BT device forwards the data without host processor involvement in at least resending the data back to its BT controller.

    Abstract: An apparatus and method for transmitting audio with coexisting wireless networks. In one embodiment, a wireless device includes a first wireless network controller and a second wireless network controller. The first wireless network controller and the second wireless network controller are configured to access a wireless communication medium via a shared antenna, and to transmit, via the wireless communication medium, data received from a host device. The second wireless network controller includes an audio stream detector configured to determine, based on the contents of the data received from the host device, whether an audio stream is to be transmitted via the second wireless network controller, and to request that the second wireless network controller be given access priority to the antenna over the first wireless network controller, based on a determination that the audio stream is to be transmitted via the second wireless network controller.
