Roving RN-42
============
07/16 After fix of voltage dividor on GPIO6, had a trouble that it could not send a char to BT module, though could receive.
Found R8 had wrong 1K resistor and changed to 10K, after that it can send to the module again. Not sure how it had sent with the wrong 1K before.
TODO
----
- Factroy reset doesn't work; need to test again. 10K pull-up is too high?
- Lipo voltage ADC sensing
- Lipo charger configuration: fast charge time: USB charger spec?
- Low voltage alarm: LED indcates voltage of Lipo

command mode
------------
To enter command mode disconnect the module from host and type '$$$'.(you will see 'CMD')
To exit type '---'.(you will see 'END')
Serial connection
-----------------
Serial line: 115200bps, 8bit, 1-stopbit, non-parity, no flow control
SSP: 115200bps, 8bit, 1-stopbit, non-parity, no flow control(via Bluetooth)
To enter command mode disconnect the module from host and type '$$$'.(you will see 'CMD')
To exit type '---'(you will see 'END') and '+' to get local echo.

Deep sleep Idle (3.1.2)
In this mode the module shuts down completly and only draws about 300uA. To enable this set the most signifant bit(0x8000) of Sniff interaval timer.
SW,8320 // deep sleep enable(interval=0x320*0.625ms)
SW,8320 // deep sleep enable(interval=0x320*0.625=500ms)
In normal sleep the firmware is still running in idle mode, and wakes up about 20 times per second to check ports, update LEDs, etc. During deep sleep, the firmware actually stops runnig some tasks and the LEDs only update about once per second.
To wake from deep sleep there are three ways: (in worst case wake up takes 5ms)
*send a charactor to the UART(first charactor will be lost)
