Abstract: A network device serving two or more networks using periodic times slots for transmission events is configured to determine that one of the periodic time slots on one of the networks has or soon will collide with one of the periodic time slots on the other network by processing time stamps for events on each network. Either of the periodic time slots may be occasionally shifted by a time shift amount to avoid a collision between the periodic time slots on each network. Shifting the periodic time slots may be performed by transmitting a Bluetooth connection parameter update packet.

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.
