摘要： 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.

摘要： 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.

摘要： 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.

摘要： Disclosed are various embodiments of Bluetooth low energy (BLE) modules and methods implemented therein. An embodiment of the disclosure generates in a BLE central device an identity resolving key (IRK) associated with a BLE peripheral device. The IRK is transmitted to the BLE peripheral. A resolvable private address (RPA) is generated in the BLE central device that corresponds to the IRK. Packets transmitted in an advertising channel use the RPA for transmissions to the BLE peripheral.

摘要： A method for input control of multiple computing devices from a single set of input devices begins by providing, by a master input device of the single set of input devices, a connection request to the multiple computing devices via a wireless channel, wherein the connection request identifies one of the multiple computing devices. The method continues by interpreting, by each of other ones of the multiple computing devices, the connection request to determine that the connection request is not addressing the each of the other ones of the multiple computing devices. In response to the connection request, the method continues by providing, by the one of the multiple computing devices, a connection response to the master input device via the wireless channel. The method continues by providing, by the one of the multiple computing devices, a slave connection request to at least one slave input device of the single set of input devices via the wireless channel. The method continues by, in response to the slave connection request, providing, by the at least one slave input device, a second connection response to the one of the multiple computing devices via the wireless channel such that the master input device and the at least one slave input device provide input to the one of the multiple computing devices via the wireless channel.
