20110021142 | METHOD AND SYSTEM FOR A DUAL-MODE BLUETOOTH LOW ENERGY DEVICE - 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. As a slave, the dual-mode BLE device updates connection parameters based on the identified idle intervals within Bluetooth BR/EDR traffic communications. | 01-27-2011 |
20110319020 | METHOD AND SYSTEM FOR MULTI-STAGE DEVICE FILTERING IN A BLUETOOTH LOW ENERGY DEVICE - 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. | 12-29-2011 |
20130165044 | Bluetooth Low Energy Module Systems and Methods - 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. | 06-27-2013 |

20140357293 | Proximity Alert Using Signal Strength - 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. | 12-04-2014 |
