Boot Protocol
=============
3.3.2
No report descriptor, fixed report descriptors defined.

Device      ReportID    Size
---------------------------------
Reserved    0
Keyboard    1           9octets
Mouse       2           4octets
Reserved    3-255

Report descriptor
-----------------
Report ID is added to USB HID boot protocol descriptor.
Boot Protocol device doesn't need to supply descriptors. and can send extra data on end of boot report this data will be ignored unless host supports report descriptor.

Report Protocol devices can have specific descriptors. Using Boot protocol descriptor followed by extra data may be useful for compatibility to Boot protocol only supported host.

NOTE:
Bluegiga HID sample say report ID of mouse is 1 but 2?
Bluegiga HID sample say report ID of consumer page is 2 but 3?
** mouse.desc and consumer.desc were fixed.
                size
keyboard.desc   67  0x43 
mouse.desc      60  0x3c
consumer.desc   82  0x52
combo.desc      209 0xd1

SET BT SSP 2 0  # 2:keyboard only 0:Man-in-the-middle protection is not needed


SET BT SSP 2 1
    bond only if MITM protection is supported by host
SET BT SSP 2 0
    bond even if MITM protection is not supported by host

On Windows 'Add device' causes SSP PASSKEY event on iWRAP
    SSP PASSKEY 78:dd:08:b7:e4:a2 ?

If device has display(0 or 1) this event occurs. User should be shown this code on the device.
    SSP CONFIRM 78:dd:08:b7:e4:a2 517572


SET BT SSP 3 0
    No input/output, No MITM protection.
    Without procedure of authentication the divice is bond to host.

Setting
========
Following settings need to be done before wiring into keyboard.
- UART speed: 38400bps(115200bps didn't work with software serial)
- No SSP procedure(without MITM protection)
