AUTOMATIC CONNECTION OF BLUETOOTH HUMAN INTERFACE DEVICES

摘要

A Bluetooth controller associated with a host device can be configured to automatically configure and setup a Bluetooth LE HID without the use of hidden menus or other setup options involving multiple steps (or other input devices). The Bluetooth controller executes background scan operations to detect at least one Bluetooth LE HID to connect to the host device. Each Bluetooth packet received at the Bluetooth controller is analyzed to determine whether the received Bluetooth packet is a predefined Bluetooth LE HID packet type transmitted by the Bluetooth LE HID. In response to determining that the received Bluetooth packet is a predefined Bluetooth LE HID packet type transmitted by the Bluetooth LE HID, the received Bluetooth packet is provided to a Bluetooth LE HID module of the Bluetooth controller. Otherwise, the received Bluetooth packet is provided to a Bluetooth HCI module of the Bluetooth controller.

主权项

1. A method comprising:
executing, at a Bluetooth controller associated with a host device, background scan operations to detect a Bluetooth device for establishing a communication link between the Bluetooth device and the host device; receiving a Bluetooth packet at the Bluetooth controller in response to said executing the background scan operations; determining whether the received Bluetooth packet is a predefined Bluetooth low energy (LE) human interface device (HID) packet type transmitted by the Bluetooth device; and providing the received Bluetooth packet to a Bluetooth LE HID module of the Bluetooth controller in response to determining that the received Bluetooth packet is the predefined Bluetooth LE HID packet type, or providing the received Bluetooth packet to a Bluetooth host controller interface (HCI) module of the Bluetooth controller in response to determining that the received Bluetooth packet is not the predefined Bluetooth LE HID packet type.
