  • Patent number: 12278698
    Abstract: A Bluetooth adaptive rate selection method can include: enabling the first Bluetooth module in the local device and the second Bluetooth module in a peer device to be in a connection state; in a first time period, obtaining RSSI of the radio frequency signal sent by the second Bluetooth module and received by the first Bluetooth module, and PER of the data packet sent by the first Bluetooth module or the maximum number of consecutive retransmissions of the data packet sent by the first Bluetooth module; and selecting the data transmission rate between the first Bluetooth module and the second Bluetooth module adaptively according to one of the PER and the maximum number of consecutive retransmissions and the RSSI.

  • Patent number: 12151519
    Abstract: A tire localization method for a vehicle, can include: matching a first Bluetooth module in each tire of the vehicle with a second Bluetooth module of a Bluetooth host in the vehicle; acquiring first data representing a received signal strength indication of a first radio frequency signal sent by the first Bluetooth module in each tire; acquiring an angle of arrival of the first Bluetooth module in each tire relative to the second Bluetooth module; and locating each tire based on the first data and the angle of arrival.

  • Patent number: 12151520
    Abstract: A tire pressure monitoring module of a vehicle, a tire localization system and a tire localization method of a vehicle are provided. Each of tires is determined to be a left tire or a right tire based on a phase relationship of components of magnetic field intensity in two different directions in the tire. The components of magnetic field intensity in two different directions are measured by a magnetometer in the tire pressure monitoring module. The tire is determined to be a front tire or a right tire based on magnitude of an AOA of a first Bluetooth module in the tire pressure monitoring module relative to a multi-antenna Bluetooth host. In this way, the tires of the vehicle are positioned automatically with a high precision. In addition, the tire pressure monitoring module may be mounted on any tire without any distinction, which reduces the installation cost.

  • Publication number: 20230179668
    Abstract: A method of enhanced broadcast concurrent OTA firmware upgrade based on Bluetooth Mesh, can include: creating nodes that meet preset conditions in a Bluetooth Mesh network into a group; selecting a root source node from the group, and performing OTA firmware upgrade for the root source node; distributing, by the root source node, OTA firmware upgrade data packets to target nodes that have not completed the upgrade in the group, based on an extended broadcast message; obtaining, by the root source node, OTA firmware upgrade status information of the target nodes in the group; and determining, by the root source node, whether to redistribute the OTA firmware upgrade data packets or respond to the request for retransmission of missing data packets, based on the OTA firmware upgrade status information.
