  • Patent number: 9860680
    Abstract: A Bluetooth controller associated with a host device can be configured to automatically configure and setup a Bluetooth LE HID without the use of hidden menus or other setup options involving multiple steps (or other input devices). The Bluetooth controller executes background scan operations to detect at least one Bluetooth LE HID to connect to the host device. Each Bluetooth packet received at the Bluetooth controller is analyzed to determine whether the received Bluetooth packet is a predefined Bluetooth LE HID packet type transmitted by the Bluetooth LE HID. In response to determining that the received Bluetooth packet is a predefined Bluetooth LE HID packet type transmitted by the Bluetooth LE HID, the received Bluetooth packet is provided to a Bluetooth LE HID module of the Bluetooth controller. Otherwise, the received Bluetooth packet is provided to a Bluetooth HCI module of the Bluetooth controller.

  • Patent number: 9811777
    Abstract: The present invention discloses a rule matching method including: receiving a packet; detecting feature information in content of the packet, and determining whether the detected feature information in the packet conforms to a classification characteristic of one rule group among a plurality of preset rule groups; if yes, determining a state machine corresponding to the one rule group as a first state machine; and determining whether the first state machine is stored in an on-chip memory, and if yes, using the first state machine to match the packet to obtain a matching result; and if no, when an off-chip memory stores the first state machine, loading the first state machine from the off-chip memory into the on-chip memory, and using the first state machine to match the packet to obtain a matching result. Embodiments of the present invention enable a product to achieve better performance.

  • Patent number: 8732319
    Abstract: A mechanism for context awareness proximity-based establishment of wireless communication connections can be implemented in Bluetooth-compatible devices for simplifying procedures for device discovery, connection, service discovery, and content exchange. In response to determining to execute a context task associated with an application associated with a first communication device, the first communication device can determine whether a second communication device is within a threshold detection distance from the first communication device. If the second communication device is within the threshold detection distance from the first communication device, the first communication device can establish a communication link with the second communication device based, at least in part, on one or more connection parameters associated with the second communication device.
