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 technique to provide frequency offset estimation for packets transmitted during a service period allocated strictly for designated source and destination devices. The destination device obtains coarse and fine frequency offset estimation from the short and long preambles. A residual frequency offset is tracked for the data blocks and combined with the coarse and fine frequency offset to obtain a total frequency offset to apply to the data blocks. The total frequency offset value at the end of the first packet is saved and, instead of again estimating the coarse and fine frequency offset values with the short and long preambles of the second packet, the saved total frequency offset value is used as the initialization value to add to the residual frequency offset in the second packet. The saved offset value at the end of each packet becomes the initialization value for the subsequent packet.

Abstract: A near field communications (NFC) device is disclosed that detects a presence of another NFC capable device within its magnetic field. The NFC device observes signal metrics of an observed detection signal at various intervals. The NFC device determines a statistical relationship based upon at least two first signal metrics from among the signal metrics to determine an estimate of at least one second signal metric from among the signal metrics. The NFC device compares a difference between the estimate of the signal metric of the at least one second signal metric and the at least one second signal metric. The NFC capable device makes a first determination that another NFC device is present within its magnetic field when the difference indicates that the at least one second signal metric is non-linearly related to the at least two first signal metrics.

Abstract: 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.
