Methods and systems for filter data packets using an advertising data packet content filter are disclosed. An example method involves maintaining, by a Bluetooth device, an advertising data content filter. The advertising data content filter includes at least one content filter having at least one respective delivery mode that specifies when to deliver data packets matching the at least one content filter to a host Bluetooth stack. The method also involves receiving, by the Bluetooth device, a data packet from an advertising Bluetooth device. The method further involves determining, by the Bluetooth device, that content of the data packet matches a particular content filter of the advertising data content filter. And the method involves providing a portion of the data packet to the host Bluetooth stack in accordance with a particular delivery mode corresponding to the particular content filter.

Short-range wireless controller filtering and reporting

A system and method for locating a network device. A location provider determines, based on location data, a location of a wireless access point. The location data includes location data from each of a plurality of network devices, wherein the location data for each network device includes the network device's location and data representative of a distance between the wireless access point and each network device. The location provider generates, based on the location of the wireless access point, location information for the wireless access point, signs the location information with a credential to form signed location information, and communicates the signed location information to the wireless access point.

Generating and publishing validated location information

A wireless device configured as a group owner determines whether all client devices paired with the group owner are currently associated with the group owner. If all paired client devices are currently associated with the group owner, the group owner enters a first mode in which the group owner is in an active mode (powered up to communicate) during a first portion of a beacon interval and is in a low power mode (in which no communication occurs) during a second portion of the beacon interval. If not all paired client devices are currently associated with the group owner, the group owner enters a second mode in which the group owner is in the active state during the first portion and at least part of the second portion of the beacon interval. The group owner and client devices are configured to operate as master and slave.

Multi-modal wireless connection management

Methods and systems for storing data regarding received advertising packets are disclosed. An example method involves determining parameters of at least one batch-scan mode for a Bluetooth device. The parameters of the at least one batch-scan mode specify a format for storing data regarding particular advertising packets that are received by the Bluetooth device when operating in the at least one batch-scan mode. The method also involves receiving, by the Bluetooth device, one or more advertising packets on an interval basis. Further, the method involves storing data regarding the one or more advertising packets into a memory of the Bluetooth device in accordance with the at least one batch-scan mode. And the method involves providing the stored data regarding the one or more advertising packets to the host Bluetooth stack.

Scanning enhancements for short-range wireless devices

An example method for providing motion detection via a Bluetooth low energy scan is disclosed. In particular, the method includes performing a scan via a Bluetooth unit of a computing device. Further, the method includes receiving one or more advertisement packets via the Bluetooth unit in response to the performed scan. The one or more advertisement packets may be associated with a respective Bluetooth device. Yet further, the method includes determining if a location of the Bluetooth unit has changed based on received one or more advertisement packets. The determining includes comparing the received one or more advertisement packets with a set of one or more reference advertisement packets. In addition, the method includes enabling an application processing unit in response to determining the Bluetooth unit has changed location. The application processing unit may be configured to determine the location of the Bluetooth unit.

Motion detection with Bluetooth low energy scan

Examples described herein involve modifying power consumption based on energy usage messages. A method includes a CPU periodically receiving energy-usage messages from components. From the energy-usage messages, the CPU determines a plurality of historical energy-usage patterns that indicate respective historical energy consumption of a given component while operating in a given operating state. Then, the CPU determines that overall power consumption of the one or more components differs from an expected power consumption. Thereafter, the CPU identifies at least one differing component that is causing the power consumption differential based on the historical energy-usage patterns and a plurality of new energy-usage messages received after the plurality of historical energy-usage patterns were determined. The CPU then causes the at least one differing component to modify an amount of energy that the at least one differing component is consuming.

Modifying power consumption based on energy-usage messages

An example method performed by a first computing device executing an operating system includes receiving a request to form, with a second computing device, a wireless communication link, and sending, to the second computing device, a first message representing the request to form the wireless communication link. The method also includes prior to the operating system providing to the application a notification that the wireless communication link has been formed, sending, to the second computing device, a second message representing a request to receive data via the wireless communication link to confirm that the wireless communication link has been formed. The method also includes receiving, from the second computing device, the data confirming that the wireless communication link has been formed, and based on receiving the data, sending via the operating system to the application, the notification indicating that the wireless communication link has been formed.

Methods and systems for forming a wireless communication link

An example method for adjusting the range of transmission of advertising packets is disclosed. In particular, method includes receiving, from an application executing on a mobile computing device, a request. The request may include a request to transmit an advertisement packet via a short-range wireless device of the computing device. Additionally, the request may include a power level for the transmission of the advertisement packet via the short-range wireless device. Additionally, the method may include causing the transmission, via the short-range wireless device, of the advertisement packet. The short-range wireless device may be configured to transmit the advertisement packet at a transmission power level less than or equal to the requested power level. Further, the requested power level may be less than or equal to a nominal power level for the short-range wireless device.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may comprise a transceiver configured to transmit uplink frames and receive downlink frames in a first transaction slot of a super-frame. The one or more of the uplink frames and the downlink frames are associated with over-allocated network allocation vectors that reserve a transmission time which exceeds a time required to transmit acknowledgements of the one or more downlink frames or receive acknowledgement of the one or more uplink frames, respectively. The apparatus may comprise a processing system configured to cause the transceiver to transmit a first uplink frame to the access point with a first over-allocated NAV, to establish a start-time for the super-frame and to extract data from two or more downlink frames in a burst received from the access point.
