Bluetooth fast connection mode for wireless peripheral device
First Claim
1. A method for operating a wireless Human Interface Device (HID) to conserve battery life, the method comprising:
- establishing a wireless connection with a host device;
receiving user input and wirelessly transmitting the user input to the host device;
after a period of time during which no user input is received, entering a power down mode in which the connection with the host device is lost;
after the connection with the host device has been lost, receiving user input;
when the connection with the host device is lost, in attempting to reestablish a link with the host device, page scanning by;
listening for pages from the host device on a first frequency of a page hopping sequence of the host device for a page scanning period that corresponds to a duration of the page hopping sequence;
listening for pages from the host device on a second frequency of the page hopping sequence of the host device for a page scanning period that corresponds to a duration of the page hopping sequence; and
receiving a page from the host device;
responding to the page from the host device; and
establishing a wireless connection with the host device.

Abstract
A wireless interface device services communications between a wirelessly enabled host and at least one user input device. The wireless interface device includes a wireless interface unit, a processing unit, an input/output unit, and a power management unit. The wireless interface unit wirelessly interfaces with the wirelessly enabled host using a communication interface protocol. The power management unit operably couples to the wireless interface unit, the processing unit, and the input/output unit. The wireless interface unit supports paging operations in which the wireless interface device is able to receive a page during a wirelessly enabled host in a page scanning period that corresponds to a duration of the page hopping sequence of the host.
