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 control mode . According to the releva...

Abstract

The invention provides a method and an apparatus for updating a connection parameter of a Bluetooth device with low power consumption. The method comprises the following steps: when detecting that aremote control mode is switched locally, sending a prompt message indicating that a Bluetooth remote control device switches the remote control mode to a controlled device, for enabling the controlled device to generate a connection parameter updating request according to the prompt message and send the connection parameter updating request to the Bluetooth remote control device, wherein the connection parameter updating request carries an effective time point of the connection parameter, and the effective time point is prior to a default effective time point; monitoring whether the connection parameter updating request sent by the controlled device is received locally at each connection interval after the remote control mode is switched locally; when monitoring the connection parameter updating request, sending response used for agreeing to update the connection parameter to the controlled device; and when reaching the effective time point of the connection parameter, updating the connection parameter of the local and the controlled device. In summary, the method and the apparatus provided by the technical scheme of the invention can be used for improving the updating speed of the connection parameter 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. It can be seen from the Bluetooth 4.0 protocol that the three connection parameters specified in the protocol: ConnectionInterval, SlaveLatency and SupervisionTimeout 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 Sla...
