  • Publication number: 20250008454
    Abstract: Some aspects of this disclosure include apparatuses and methods for implementing a synchronized short range communication protocol scan mechanism across multiple devices. Some aspects relate to an electronic device including a transceiver configured to communicate based on a short range communication protocol and a processor communicatively coupled to the transceiver. The processor receives one or more parameters from a peripheral electronic device and determines, based at least on the one or more parameters, one or more synchronization parameters. The processor further transmits the one or more synchronization parameters to the peripheral electronic device. The one or more synchronization parameters can include at least a scan offset associated with the peripheral electronic device.

  • Publication number: 20240334361
    Abstract: An example system includes an application processor (AP), a transceiver associated with a firmware layer and a controller. The controller is configured to perform operations that include receiving data representing a clock synchronization request from a remote device, such as a UWB clock synchronization request. The request is received by the transceiver over a wireless communication link. The controller generates a response to the synchronization request. The response is configured for synchronizing a remote clock of the remote device and a local clock of the mobile device. The controller sends, to the remote device by the transceiver, the response to the synchronization request.

  • Publication number: 20240107544
    Abstract: The present disclosure relates to techniques for localizing devices connected to wireless networks, such as wireless mesh networks. In particular, a device connected to a wireless mesh network may maintain and share information, such as location data and identifiers, regarding the device and other devices connected to the device. The device itself or a computing system to which the device connects may determine locations for the devices in the wireless mesh network and generate a device map that indicates the locations of the devices.

  • Patent number: 11838963
    Abstract: Methods, systems, and apparatuses are presented to utilize Bluetooth (BT) radios to synchronize ultra wideband (UWB) radios, to allow the UWB radios to operate within narrow transmit/receive windows, which may lead to power savings. In some implementations, a transmitting UWB radio and a receiving UWB radio may synchronize the expected time of an UWB transmission based on BT events, such as receiving a BT advertisement, or establishing a BT connection. In some implementations, the transmitting UWB radio and the receiving UWB radio may synchronize the expected time of an UWB transmission based on synchronized event counters maintained by the BT radios. Information regarding UWB transmission start times may also be passed via BT communications, in some implementations.

  • Patent number: 11693467
    Abstract: Embodiments disclosed herein relate to reducing a power consumption of an electronic device while maintaining some functionality of the electronic device while the electronic device is in a low power mode. The device may be in the low power mode due to a battery level being below a threshold. If the battery level is below the threshold, the electronic device may enter the low power mode. However, before entering the low power mode, some functionality of an application processor may be transferred to a communication controller. Once the functionality is transferred, the application processor may be disabled to reduce power consumption while maintaining functionality of the application processor. The electronic device may also utilize various communication protocols to communicate with a peripheral device. Even though the electronic device may be in the low power mode, the communication controller may be used to cause the peripheral device to perform various actions.

  • Publication number: 20220201429
    Abstract: Embodiments described herein provide for an electronic device comprising a wireless processor coupled with a wireless radio, memory to store instructions, and one or more processors to execute the instructions. The one or more processors, based on the instructions, are to scan for a beacon advertisement using the wireless processor, store the beacon and a timestamp in a beacon advertisement buffer in response to detection of the beacon via the wireless processor, correlate a beacon advertisement with stored location data to determine a location estimate for a device associated with the beacon advertisement, encrypt the location estimate for the beacon advertisement using a beacon identifier broadcast with the beacon identifier, and transmit a hash of the beacon identifier and an encrypted location estimate for the beacon advertisement to a device locator server.
