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： Certain aspects of a method and system for providing wireless communication may comprise encoding within a single chip, FM audio data received by a FM radio. The encoded received FM audio data may be translated within the single chip to a Bluetooth compatible format. The translated received FM audio data may be communicated to at least one off-chip Bluetooth enabled device via the Bluetooth radio via at least one of the following: a synchronous connection oriented (SCO) link, an extended SCO (eSCO) link, and an advanced audio distribution profile (A2DP) link. The received FM audio data may be communicated via a dedicated link that couples the FM radio to a PCM interface that handles the encoding.

摘要： Certain aspects of a method and system for routing of FM Data to a Bluetooth A2DP link may comprise converting FM data to A2DP format by processing the FM data within a single chip with integrated Bluetooth and FM radios. The A2DP formatted data may be communicated to a Bluetooth device via an ACL link using an A2DP profile. The single chip may receive at least one signal, or command, from a host that starts conversion and transmission to at least one Bluetooth device via the ACL link using the A2DP profile and may, after receiving the initiation by the host, convert the FM data to A2DP formatted data without further intervention from the host. Power may be reduced to at least a portion of the host during the conversion process if the host is not needed for other processes.

摘要： Certain aspects of a method and system for transporting FM data over a Bluetooth HCI link may comprise processing FM signals in a single chip that comprises integrated Bluetooth and FM radios. The processed signals may be communicated to a host communicatively coupled via the HCI. The processed signals may comprise samples of the left and right channels of the analog baseband FM signal. The processed signals may be communicated to the host via a L2CAP connection over the HCI. Each L2CAP packet may comprise alternating left then right channel samples. Or the samples of one channel may be placed before the samples of the other channel. The number of samples for one channel may be the same as the number of samples for the other channel in each L2CAP packet. Furthermore, the samples in the L2CAP packets may be compressed.

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： In a radio comprising a transmitter and a receiver, transmission and reception of signals may be controlled based on received signal strength measurements from a signal strength indicator module and transmitted signal strength measurements from the signal strength indicator module. For the transmitted signal strength measurements, the shared signal strength indicator module may measure signal strength of a signal output by a power amplifier. For the received signal strength measurements, the shared signal strength indicator module may measure signal strength of a received signal. A capacitance coupled to an output of the power amplifier may be configured based on a frequency of the signal output by the power amplifier. A gain of the power amplifier may be controlled based on the transmitted signal strength measurements. For the transmitted signal strength measurements, an analog-to-digital converter may process the signal output by the power amplifier.
