52015/11/24
6JP Bluetooth:
7 RN-42 cannot send Japanese keys like; henkan, mu-henkan and kana, JPY and RO.
8 It seems HID usage more than 0x65 cannot be send with the module.

22 - configure the module as HID device every time powering up
23 - this'll reduce work load of assembly
24
25- move rn42 to protocol directory when it becomes reusable stack
26
27- sendchar() in lufa.c no buffer
28 - no buffering. character lost can be caused.
29- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).

53- HHKB matrix.c needs matrix_prev?
54 - is_modified() is obsolete now. really needs?
55- ADC: removing AREF capacitor C10
56 - seems to be better while usb powered
57 - still bad while battery powered
58 http://electronics.stackexchange.com/questions/105849/avcc-and-capacitor-using-adc
59- ADC: smaller resistors for voltage dividor

166TROUBLE SHOOT
167-------------
16807/16 After fix of voltage dividor on GPIO6, had a trouble that it could not send a char to BT module, though could receive.
169 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.
170
17107/18 On Linux, had an USB related trouble; keyboard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.
172
17312/07 rn42_rts() read 1 every time. R12 broke in open mode(no coductive), idk why, too much heat with soldering? and PF1 pin was not soldered.
174 It resolved with resoldering PF1 and new resistor on R12.

1RN-42 Bluetooth Module Support
2==============================
3Bluetooth controller board works with HHKB Pro2, JP, Type-S and Type-S JP and it supports both USB and Bluetooth as keyboard output protocol. Bluetooth module Roving Networks/Microchip RN-42 is installed on the board.
4
5
6RN-42:
7http://www.microchip.com/wwwproducts/Devices.aspx?product=RN42
8
9
10Capabitlities:
11- USB keyboard functions
12 completely equivarent to USB controller including mouse keys and NKRO.
13- Switching between USB and Bluetooth
14 You can switch the two connections with BT switch or key combination.
15- RN-42 config mode
16 You can change power/connection configuration of the module if needed.
17- Low battery alert
18 Red LED turns on when low voltage.
19- RN-42 status indicator
20 LED indicates status of Bluetooth connection.
21- Pairing
22 The module stores up to 8 connections.
23- Auto connect
24 The module connects the last connected device automatically.
25- iOS support
26 works as keyboard with iPhone5. No tested completely.
27- Android support
28 works as keyboard and mouse with Nexus5. No tested completely.
29- Mouse keys over BT
30 Note that iOS doesn't accept mouse device.
31
32
33Limitations:
34- Short battery life
35 Around 12hr with 1000mAh
36- No connection switching
37 RN-42 auto-connects to the last connected device.
38 Some of consumer products can switch between devices, for example Logitech K480.
39 http://www.logitech.com/en-us/product/multi-device-keyboard-k480?crid=26
40- HHKB JP requires case modification for BT switch and LEDs.
41 without switch power controlled by MCU? Probably using 3.3V regulator enable pin power of RN-42 can be controlled.
42
43NOTE:
44- LIPO BATTERY IS VERY DANGEROUS, TAKE EXTRA CARE OF YOUR SAFETY AND PROPERTY.
45- RN-42 version 6.15 is supported.
46- No NKRO over Bluetooth
47- Check you country's wiress regulation and certification of RN-42.

2873.7.1.5 Note: To connect with Android phone the modules must wake up 11ms every 2.5seconds.
288
289
290Power Management
291----------------
292Inquiry and Page window Idle or Active (3.1.1)
293 Downside: delay in discovery or connection time
294 SI, // set inquiry scan window(discovery) on/off duty?
295 SJ, // set page scan window(connection)
296 This reduces averaege power >20mA to 5mA(3mA in Sniff mode)
297
298Sniff mode Transmit
299 Sniff mode is disabled by default and radio is active continuously when connected.(25-30mA)
300 In Sniff mode the radio wakes up intermittently and sleeps in very low power mode.(2mA)
301 SW,<val> // set interval timer(*0.625ms) 0000-7FFF
302
303Deep sleep Idle (3.1.2)
304 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.
305 SW,8320 // deep sleep enable(interval=0x320*0.625=500ms)
306 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.
307 To wake from deep sleep there are three ways: (in worst case wake up takes 5ms)
308 *send a charactor to the UART(first charactor will be lost)
309 *toggle CTS low to high and wait 5ms
310 *wake automatically every slot time(<val>*0.625ms)
311 Once the radio is awake it stay active for exactly 1 second of inactivity and then sleeps again.
312 Downside: latency and data loss
313
314Disable Output driver Idle or Active (3.1.3)
315 S%,1000 // set all GPIO pins(0-11) to inputs.
316
317Lower Transmit Power Idle or Active (3.1.4)
318 SY,<hex> // transmit power setting(takes effect after a power cycle and reboot)
319 Downside: reducing effective range
320
321
322Optimizig for Latency
323---------------------
324By default the firmware is optimized for throughput.
325SQ,16 // set latency bit
326SQ,0 // unset latency bit
327
328
329Configuration timer settings
330----------------------------
331Remote configuration is used for the module to be configured with various commands over Bluetooth(SPP profile only?).
332
333The module has remote configuration timer to allow remote configuration over Bluetooth after power up in Slave mode. In Master modes the remote configuration timer is set to 0(no remote configuration). (In Trigger Master mode the timer is used as an idle timer to break the connection after time expires with no charactors receive.)
334 ST,0 // no remote, no local when connected
335 ST,<1-252> // local and remote with timeout in seconds from power up
336 ST,253 // local only without timeout
337 ST,254 // remote only without timeout
338 ST,255 // local and remote without timeout
