  • Publication number: 20240179780
    Abstract: A system and method for transferring Bluetooth synchronization from a first Bluetooth device to a second Bluetooth device is disclosed. The first Bluetooth device may already be connected to a remote Bluetooth device. The method includes synchronizing time between the first Bluetooth device and a second Bluetooth device. After time has been synchronized, all relevant information concerning the connection is transmitted to the second Bluetooth. This may be done using an out of band network, such as UART, SPI, Ethernet, or a different wireless network. Once the first Bluetooth device has emptied its transmit queue, it may transfer communication responsibility to the second Bluetooth device.

  • Patent number: 11777637
    Abstract: Systems and methods for detecting and protecting against phase manipulation during AoA or AoD operations are disclosed. For AoA operations, the network device receiving the constant tone extension (CTE) generates an antenna switching pattern, which may be randomly generated. The network device then receives the CTE using a plurality of antenna elements. In one embodiment, the network device compares the phase of portions of the CTE signal received that utilize the same antenna element. If the phase of these portions differs by more than a threshold, the network device detects a malicious attack and acts accordingly. In another embodiment, if the AoA algorithm cannot determine the angle of arrival, the network device detects a malicious attack and acts accordingly. For angle of departure operations, the network device that transmits the CTE signal generates the antenna switching pattern and transmits it to the position engine, which performs the comparisons described above.
