    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: 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 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 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.
