Bulegiga WT12
=============
WT12 is a bluetooth module from Bluegiga. http://www.bluegiga.com/

iWRAP
    higher layer interface for bluetooth firmware
    communicate with UART

iWRAP HID
default setting
    115200  8bit/n/1/n


TODO
----
KiCAD circuit/PCB design
power saving
    AVR sleep(15ms by watch dog timer)
    WT12 sleep
    measuring current consumption
    measuring battery life of normal usage/idle/intensive usage
software reset/bootloarder
LED indicator(chaging/paring/connecting)
license confirmation of suart.c
consumer page is not working
authenticate method/SSP
SPP keyboard support
SPP debug console support
mouse wheel feature request to Bluegiga


Problems
--------
power consumption
no consumer page support(bug?)
no mouse wheel support
no paring management
no interactive auth method


UART hardware flow control
--------------------------
(iWRAP4 User Guide 9.5)
Hardware flow control is enabled by default and it should not be disabled unless mandatory, because without the hardware flow control the data transmission may not be reliable.
If the hardware flow control is enabled from PS-keys, but no flow control is used, the following steps should be implemented in the hardware design:
- CTS pin must be grounded
- RTS pin must be left floating


Power Saving
------------
power consume
    without opimization: 4hr to shutdown(310mAh)
    2011/08/25: 9hr(310mAh) SNIFF MASTER sleep/WDTO_120MS

measure current consumption
    HHKB keyswitch matrix board
        idle
        scanning
    Bluegiga WT12 module
        SLEEP command
        deep sleep on/off in config bits

HHKB keyswich
    how to power off
        I/O pin configuration when sleeping
        FET switch for 5V regulator

Bluetooth module
    power off when in USB mode
    power off by FET switch

AVR configuration

Pairing Security
----------------
Secure Simple Pairing(SSP)
    SET BT SSP 2 0  // Enables SSP for keyboard and Man-in-the-middle protection
    SET BT SSP 3 0  // Enables SSP just works mode

for keyboard with SSP
    SET BT AUTH * 0000
    SET BT SSP 2 0
    SET CONTROL CONFIG 800
    RESET

for keyboard without SSP
    SET BT AUTH * 0000
    SET CONTROL CONFIG 800
    RESET

AUTH
    AUTH xx:xx:xx:xx:xx:xx?         // Pairing request event
    AUTH xx:xx:xx:xx:xx:xx  0000

    SSP PASSKEY 78:dd:08:b7:e4:a2 ?
    SSP PASSKEY 78:dd:08:b7:e4:a2 xxxxx
