  • Resource sharing priority
    Patent number: 9277415
    Abstract: A device implements multiple protocols that share overlapping resources. In some cases, a first operation, such as a scan, may have a resource conflict with a second operation associated with a different protocol. In some cases, determining grant normal priority level requests associated with the first operation over those at the normal priority level associated with the second operation may lead to operator-noticeable degradation in device performance. A protocol controller may request a selected portion of the first operation at a low priority level. Requesting the selected portion at the low priority level may allow the second operation to selectively override the portion of the first operation. The selective overriding of the first operation may allow for execution of the first and second operations without operator-noticeable performance degradation.

  • Host controller interface and messaging method for ANT applications
    Patent number: 9258671
    Abstract: A system and method using ANT and/or ANT+ protocols for one or more ANT and/or ANT+ applications. The system can include a Bluetooth interface and a Host Controller Interface (HCI) that are configured to process incoming and outgoing ANT and/or ANT+ messages from/to one or more ANT and/or ANT+ enabled devices. The ANT and/or ANT+ messages can be communicated to one or more ANT and/or ANT+ enabled devices utilizing a Bluetooth transceiver. The Bluetooth interface and the HCI can be configured to wrap one or more ANT and/or ANT+ messages with a header and/or to remove a header from one or more wrapped ANT and/or ANT+ messages. The header can be an HCI compatible header.
