+Roving RN-42
+============
+
+
+TODO
+----
+- USB connection check
+- BT on/off check: whether RX line is pulled up?
+- 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?
+- USB/BT switching BT is on -> BT, BT is off -> USB
+
+- Low voltage lock out LVLO of DC converter for protection of Lipo
+- Lipo charger configuration: fast charge time
+- Low voltage alarm: LED indcates voltage of Lipo
+
+- Power saving: HHKB scan, BT radio control
+
+- Serial API callback when data are available/received(and when send buffer is available)
+- Serial API instance several serial ports can be used

+
+Pairing
+-------
+First, host initiates pairing process and once it is done, auto connect will work thereafter.
+SM,3 Master mode
+SM,4 Auto Connect DTR Mode uses GPIO6 to make and break connection(Mode =DTR)
+ confirm: auto connect works and control connection with GPIO6
+SM,5 Auto Connect ANY Mode (Mode =ANY)
+ each time GPIO is set, make inquiry and connect to the first found device
+SM,6 automatically reconnect(Mode =Pair)
+ confirm: auto connect works well but difficult to enter command mode.
+
+
+Fast data mode
+--------------
+The module enters fast data mode after 'remote configuration timer' window is passed from power on.
+In this mode the module does not accept '$$$' to enter command mode.
+
+Power Management
+----------------
+Inquiry and Page window Idle or Active (3.1.1)
+ Downside: delay in discovery or connection time
+ SI, // set inquiry scan window(discovery) on/off duty?
+ SJ, // set page scan window(connection)
+ This reduces averaege power >20mA to 5mA(3mA in Sniff mode)
+
+Sniff mode Transmit
+ Sniff mode is disabled by default and radio is active continuously when connected.(25-30mA)
+ In Sniff mode the radio wakes up intermittently and sleeps in very low power mode.(2mA)
+ SW,<val> // set interval timer(*0.625ms) 0000-7FFF
+
+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)
+ 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)
+ *toggle CTS low to high and wait 5ms
+ *wake automatically every slot time(<val>*0.625ms)
+ Once the radio is awake it stay active for exactly 1 second of inactivity and then sleeps again.
+ Downside: latency and data loss
+
+Disable Output driver Idle or Active (3.1.3)
+ S%,1000 // set all GPIO pins(0-11) to inputs.
+
+Lower Transmit Power Idle or Active (3.1.4)
+ SY,<hex> // transmit power setting(takes effect after a power cycle and reboot)
+ Downside: reducing effective range
+
+
+Optimizig for Latency
+---------------------
+By default the firmware is optimized for throughput.
+SQ,16 // set latency bit
+SQ,0 // unset latency bit
+
+
+Configuration timer settings
+----------------------------
+Remote configuration is used for the module to be configured with various commands over Bluetooth(SPP profile only?).
+
+The 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.)
+ ST,0 // no remote, no local when connected
+ ST,<1-252> // local and remote with timeout in seconds from power up
+ ST,253 // local only without timeout
+ ST,254 // remote only without timeout
+ ST,255 // local and remote without timeout
+
+
+Android
+-------
+3.7.1.5 Note: To connect with Android phone the modules must wake up 11ms every 2.5seconds.
