  • Patent number: 11134534
    Abstract: An apparatus includes multiple radio-frequency (RF) circuits, a number of Bluetooth (BT) cores and a processor. The BT cores are coupled to the plurality of RF circuits. The processor is coupled to the BT cores to control operations of the RF circuits and the BT cores. The RF circuits, the BT cores and the processor are implemented as a system on a chip (SoC). Controlling the operations of the RF circuits and the BT cores can be performed by controlling register spaces associated with the RF circuits and the BT cores.

  • Patent number: 10645735
    Abstract: In some aspects, the disclosure is directed to methods and systems for an enhanced data rate, low energy wireless communication. Devices may communicate over predetermined wireless bands such as the 2.4 GHz and 5 GHz ISM bands, using ?/4-differential quadrature phase shift keying, with physical layer rates of 1, 2, 4, 8 Mbps or higher. Symbol timing may be at any frequency, and may be 256 ns in some implementations. In some implementations, to extend device battery life, devices may use a low latency reconnect mechanism allowing frequent hibernation or shutdown of transmitters and/or carriers.

  • Patent number: 9706496
    Abstract: A technique to open a single receiving window to perform scanning and initiating operations in a Bluetooth Low Energy compliant device, instead of using two separate receiving windows to perform the equivalent operations. The combining of the scanning and initiating operations in one receiving window, instead of two separate windows, reduces power consumption and provides for bandwidth efficiency.

  • Patent number: 9408147
    Abstract: A method of communicating data in a Bluetoothâ„¢ 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.

    Abstract: A system and method using ANT and/or ANT+ protocols for one or more ANT and/or ANT+ applications. The system can include a Bluetooth interface and a Host Controller Interface (HCI) that are configured to process incoming and outgoing ANT and/or ANT+ messages from/to one or more ANT and/or ANT+ enabled devices. The ANT and/or ANT+ messages can be communicated to one or more ANT and/or ANT+ enabled devices utilizing a Bluetooth transceiver. The Bluetooth interface and the HCI can be configured to wrap one or more ANT and/or ANT+ messages with a header and/or to remove a header from one or more wrapped ANT and/or ANT+ messages. The header can be an HCI compatible header.

  • Patent number: 9210570
    Abstract: Systems and methods for implementing Bluetooth Low Energy (BLE) communications are provided. In some aspects, a method includes receiving, by a first BLE device, a first advertisement packet from a second BLE device. The first advertisement packet includes a payload encrypted based on a predetermined key. The method also includes decrypting the payload of the first advertisement packet using the predetermined key. The method also includes processing, by the first BLE device, the decrypted payload. At least one of the receiving, the decrypting, or the processing is performed without a BLE connection being established between the first BLE device and the second BLE device.

  • Patent number: 9185652
    Abstract: 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.
