Abstract
A method is provided for updating a connection parameter of a low-power Bluetooth device. The method includes, upon detection of a local switch of remote control modes, transmitting, to a controlled device, a prompt message indicating the local switch, such that a request for updating a connection parameter is generated based on the prompt message and transmitted to a Bluetooth remote control device. A valid time for the connection parameter is carried in the request, and is earlier than a default valid time. The method also includes monitoring, for every connection interval after the local switch, whether the request is received locally. The method also includes upon detection of the request, transmitting, to the controlled device, a response for agreeing to update the connection parameter. The method further includes updating the connection parameter between the Bluetooth device and the controlled device, when the valid time for the connection parameter arrives.
