This chapter will show you much knowledge about bluetooth technology. 

 

Bluetooth is a standard for a small , cheap radio chip to be plugged into 
computers, printers, mobile phones, etc.A Bluetooth chip is designed to 
replace cables by taking the information normally carried by the cable, and 
transmitting it at a special frequency to a receiver Bluetooth chip, which will 
then give the information received to the computer, phone whatever. 

 

bluetooth hid stack is a protocol stack that defines how devices with Bluetooth 
wireless communications can use the HID Protocol initially to discover the 
feature set of a HID, and then communicate with the HID.  

  

hid dongle is a Bluetooth hardware with Universal Serial Bus (USB) port. and 
the hardware is working like a standard USB composite device with a HID 
Keyboard and a HID Mouse. Bluetooth Keyboard and Bluetooth Mouse can 
connected to the hid dongle automatically when they paired during connecting. 
and bluetooth hid devices will work like a standard USB keyboard and USB 
mouse. hid dongle can be switched to hci mode.  

 

In this mode the device will appear as a USB Composite Device containing 
HID keyboard and HID mouse functionality. In this mode, USB VendorID = 
0x0458 ProductID = 0x1000. 
On start up, the radio will become connectable to allow the last used Bluetooth 
mouse and keyboard to reconnect. See Last Used Devices for details of how 
these are determined. The page-scan interface is set to 100ms to allow the 
devices to reconnect quickly. 
When the mouse and keyboard become active, they will reconnect to the USB 
device and the Bluetooth HID reports will be translated to USB HID and 
passed to the host via the appropriate HID endpoint. 
If the Bluetooth HID mouse or keyboard connection is lost at anytime, the 
dongle will enter page scan again to allow the device to reconnect.
