Embodiment Construction

[0121] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0122] With the continuous development of Bluetooth technology, BLE (Bluetooth Low Energy, Bluetooth Low Energy) technology supported by Bluetooth 4.0 protocol is widely used in the field of wireless remote control. In addition to supporting the traditional button remote control mode, Bluetooth remote control devices can also support voice remote mode. According to the relevant regula...

Abstract

The disclosure provides a method and device for updating connection parameters of a Bluetooth low-power device. The method includes: when it is detected that the local remote control mode is switched, sending a prompt message to the controlled device to switch the remote control mode of the Bluetooth remote control device, so that the controlled device The device generates a connection parameter update request according to the prompt message, and sends it to the Bluetooth remote control device. The connection parameter update request carries the effective time point of the connection parameter, which is earlier than the default effective time point; Each connection interval monitors whether the connection parameter update request sent by the controlled device is received locally; when the connection parameter update request is detected, a response for agreeing to update the connection parameters is sent to the controlled device; when the effective time of the connection parameter When arriving, update the connection parameters between the local and the controlled device. To sum up, the technical solution of the present disclosure can improve the update speed of the connection parameters by improving the response speed of the Bluetooth remote control device.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for updating connection parameters of a Bluetooth low energy device. Background technique [0002] With the continuous development of Bluetooth technology, the BLE (Bluetooth Low Energy, Bluetooth Low Energy) technology supported by the Bluetooth 4.0 protocol is widely used in the field of wireless remote control, making the functions of Bluetooth remote control devices more and more abundant. According to the Bluetooth 4.0 protocol, the three connection parameters stipulated in the protocol: Connection Interval, Slave Latency and Supervision Timeout determine the power consumption and data transmission capability of the Bluetooth remote control device. [0003] In related technologies, the Bluetooth remote control device may initiate a connection parameter update session to the controlled device communicating with it after the Slave Late...
