This is an explanation of the type of BT that it is:
Human Interface Device Profile (HID)
Provides support for devices such as mice, joysticks, keyboards, as well as sometimes providing support for simple buttons and indicators on other types of devices. It is designed to provide a low latency link, with low power requirements. PlayStation 3 controllers and Wii Remotes also use Bluetooth HID.
Bluetooth HID is a lightweight wrapper of the Human Interface Device protocol defined for USB. The use of the HID protocol simplifies host implementation by enabling the re-use of some of the existing support for USB HID to also support Bluetooth HID.
