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)
