Abstract: Techniques are described for interference reductions using, e.g., a Received Signal Strength Indicator (RSSI) or packet error rate threshold. User Equipment that implements these techniques may reduce interference among personal area network enabled devices, for example, with the added benefit of reducing power consumption by reduced radio frequency transmissions. By reducing interference, the performance of personal area network devices may be improved.

Abstract: In some aspects, the disclosure is directed to methods and systems for virtual angle-of-arrival (AoA) or angle-of-departure (AoD) tracking for virtually tracking multiple Targets. The wireless devices (e.g. Tracker and Targets) may participate in a mesh configuration and share data within the mesh. A first device may purport to be a virtual tracker, while acting as an AoA or Angle of Departure (AoD) Target. The devices being tracked (e.g. virtual targets), may instead operate as Trackers. Processor- and energy-intensive calculations may be distributed to the virtual targets and transmitted via the mesh for aggregation at the virtual tracker.

Abstract: A system for facilitating communications in a mesh network is provided. One or more devices of the mesh network may participate as routing nodes to provide range extension for any other devices in the mesh network that would otherwise be out of range from one another. In one or more implementations, Bluetooth Low Energy (BLE) may be used as the physical transport of the mesh network.

Abstract: A monitoring device may monitor its proximity to a monitored station. The monitored station may transmit a proximity indicator to the monitoring device. For example, the proximity indicator may include the received signal strength of a signal sent by the monitored station. Wireless interface control circuitry at the monitoring device may monitor the status of the proximity indicator for changes. If one or more criteria set by an application processor are met by a detected change, the wireless interface control circuitry may send a status update to the application processor. In the criteria are not met, generation of the status update may be forgone. The application processor need not monitor the proximity indicator status and may remain in a reduced power consumption mode for longer periods.

Abstract: A technique to open a single receiving window to perform scanning and initiating operations in a Bluetooth Low Energy compliant device, instead of using two separate receiving windows to perform the equivalent operations. The combining of the scanning and initiating operations in one receiving window, instead of two separate windows, reduces power consumption and provides for bandwidth efficiency.

Abstract: A method of communicating data in a Bluetooth™ low energy (BLE) module is provided. The method includes modulating an outbound communication signal into a modulated signal with a particular modulation scheme based on a modulation type, and transmitting the modulated signal to a remote device via a wireless communication connection associated with the modulation type. The method also includes receiving an inbound radio frequency (RF) signal, determining if the inbound RF signal is associated with a modulation type, and demodulating the inbound RF signal with a particular modulation scheme based on the modulation type if the inbound RF signal is determined to be associated with a modulation type. In some aspects, the inbound RF signal and outbound modulated signal have symbol rates of 2 Megasymbols per second. In some implementations, the method includes switching between a legacy BLE system and an enhanced rate BLE system.

Abstract: A method for managing connectivity of a central device with a peripheral device is provided. The method includes determining a location of a central device, determining a proximity of the central device to a peripheral device group based at least in part on a comparison of the location of the central device to a location profile associated with the peripheral device group and adjusting a scanning duty cycle of the central device in response to the determined proximity of the central device to the peripheral device group. Bluetooth Low Energy modules and systems are also provided.

Abstract: Disclosed are various embodiments of Bluetooth low energy (BLE) modules and methods implemented therein. An embodiment of the disclosure can obtain in a BLE module an advertiser packet transmitted by a BLE advertiser. An advertiser cache can be checked to determine whether the advertiser cache in the BLE module contains an entry associated with an advertiser address from the advertiser packet. The BLE module can determine whether a payload value of the advertiser packet has changed relative to a previous advertiser packet associated with the advertiser address. The BLE module can then suppress forwarding of the packet to a host processor and/or on-board processor executing firmware. The BLE module can also suppress sending a scan request packet back to the BLE advertiser.

Abstract: A Bluetooth low energy (BLE) device receives advertising packets from an advertising BLE device. The BLE device filters the received advertising packets utilizing hardware to search for the advertiser. If the advertiser is not found by the hardware, the packet filtering continues utilizing firmware. Device identity information, comprising non-private and/or private device identities, of preferred BLE devices is partitioned to form a different white list for the hardware, firmware, and host, respectively, to concurrently support privacy and white listing. If the advertiser is found by the hardware, the hardware sends a response to the advertiser following a successful CRC check performed in the hardware. If the advertiser is found by the firmware, the device identity information of the advertiser is inserted in the white list for the hardware. The host may be awakened based on the device configuration and/or attribute type information of the received advertising packets.

Abstract: A dual-mode BLE device identifies idle intervals within Bluetooth BR/EDR traffic communications. The identified idle intervals are used by the dual-mode BLE device to concurrently perform various BLE activities. For example, advertising packet transmissions, advertising packet scanning, connection setup, and/or data packet communication may be concurrently performed within identified idle intervals within the Bluetooth BR/EDR traffic communications. Packet transmission timing, advertising interval, scan window, and/or packet size are determined based on the identified idle intervals within the Bluetooth BR/EDR traffic communications. A scan window is adjusted based on timing of expected advertising transmissions and/or advertising interval(s) for saving power. BLE packets and Bluetooth BR/EDR packets may be detected in a single advertising channel. Maximal payload size is set based on the identified idle intervals within Bluetooth BR/EDR traffic communications.
