Roving RN-42
============
-
TODO
----
-- Lipo charger configuration: fast charge time
-- Low voltage alarm: LED indcates voltage of Lipo
-- CTS/RTS lines are needed? just connect in loop back if no flow control is needed.
-- CTS is needed for waking up from deep sleep?
-- Serial API callback when data are available/received(and when send buffer is available)
-- Serial API instance several serial ports can be used
+Power saving:
+- When not connected in a few minuts get into deep sleep to save battery life
+- CTS is needed for waking up from deep sleep? How deep sleep is activated?
+
+Improving:
+- Status LED; connecting, liked, low battery, sleeping, deep sleeping
+- Battry voltage display by command; like full(solid), medium(blink), low(flash)
+- move rn42 to protocol directory when it becomes reusable stack
+- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).
+
+Testing:
+- Factroy reset doesn't work; need to **test again** 10K pull-up is too high?
+- Lipo voltage ADC value is not stabilized
+- DCDC converter: squeaky inducter; try other inductors
+
+- Keymap layer bug: during space is pressed(mousekey) press Fn(HHKB) then release space before Fn, in result HHKB layer is locked(toggled) unintentionally.
+
DONE:
+- Lipo charger configuration: fast charge time: USB charger spec? -- used 2kohm
+- use LED of charger to alarm low battery. LED should be powered directly from Lipo? - cancel; powered from VUSB
+- Use RTS in serial_uart.c to resolve missing chars from help message of RN-42 - done
+- CTS/RTS lines are needed? just connect in loop back if no flow control is needed. - done
+- add IO pin to charger status CHRG; LED control(low) and detect charge status(input HiZ) 07.24
+- LINKED: add trace on PIO2 to PF6 07.24
+- Lipo voltage ADC sensing
+- Lipo charger MCP73831: needs capacitor 4.7uF *2
- USB connection check - 07.01
- BT on/off check: whether RX line is pulled up? - checking RTS 07.01
- USB/BT switching BT is on -> BT, BT is off -> USB - 07.01
- Under voltage lock out UVLO for protection of Lipo - Lipo has discharge protection at 3.100V 07.01
- Power saving: HHKB scan, BT radio control - 9h with 850mAh, this is enough 07.01
+- Power selector doesn't work; Q4 MOSFET leaks from Lipo to USB power line. -- use Schottky instead 07/04

+TROUBLE SHOOT
+-------------
+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.
+
+07/18 On Linux, had an USB related trouble; keyobard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.

-Cannot supported without apple iAP authentication chip.
+Keyboard can be used with iPhone, but mouse cannot.
+To operate iOS with keyboard is not so useful, though.
+There may be iOS specific scancodes?

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)
V display firmware version
W wake from quiet mode enable discovery and connection
