17. Fix the bug: The main UI will crash sometimes after exit the "BLUETOOTH SETTING MENU"
18. Fix the bug: Charger sometimes won't work

Tips & Note:
#### Most of the CI-V instructions compatible with ICOM-705
#### Ham Radio Deluxe may not recognize the bluetooth virtual serial port
#### Serial port remap (could be critial when working with the bluetooth virtual serial port):
Why remap:
FLRIG/WSJTDX/JTDX may fail to connect to the bluetooth virtual serial port (due to the mechanism of rfcomm itself)

Roadmap and Tools:
com0com:
1) install com0com
2) Run "Setup Command Prompt" (the CLI for com0com)
install protname=COMxxx -
xxx is the port number, choose a unoccupied one, for example: 88
3) Close the CLI
hub4com:
1) Enter hub4com dir, looks like this:
X:\hub4com-2.1.0.0-386>
2) Input the command in the MS CLI
hub4com --route=All:All \\.\COMyyy \\.\CNCB0
COMyyy is the bluetooth virtual serial port number, for example: COM4
hub4com --route=All:All \\.\COM4 \\.\CNCB0
The CLI's output should be look like the below:
COM4 Open("\\.COM4", baud=19200, data=8, parity=no, stop=1, octs=on, odsr=off, ox=off, ix=off, idsr=off, ito=0) - OK
CNCB0 Open("\\.CNCB0", baud=19200, data=8, parity=no, stop=1, octs=on, odsr=off, ox=off, ix=off, idsr=off, ito=0) - OK
Route data COM4(0) --> CNCB0(1)
Route data CNCB0(1) --> COM4(0)
Route flow control COM4(0) --> CNCB0(1)
Route flow control CNCB0(1) --> COM4(0)
Started COM3(0)
Started CNCB0(1)
FLRIG/WSJTDX/JTDX:
1) Com port for CI-V should be the one we choose in the com0com, which in this case would be COM88

This version: range 0~50, default 20; actual gain -10~+15dB, step 0.5dB

Base: V1.1.5 Apr 9 2022,17:14:40
1. Fix bug: battery can't be fully charged
2. Fix bug: won't charge at power off state (occasionally)
3. Fix bug: have to switch band or press PTT once at the first time of power up, or there's no output RF power

App: V1.1.4 Feb 16 2022,17:15:50
1. Add FFT peak hold switch, GEN > DISPLAY SETTING > FFT PK HOLD
2. Fix bug "Gate Way" can't save in "WLAN" setting page
3. Change rx volume from 0-50 to 0-55(5dB more than prev version)
4. Change CW decoder's threshold to a higher level(better robustness but needs higher SNR)
5. Calibrate the RX S-Meter giving more accuracy
6. Add ALC level indicator(at the top-right of the bandscope area, below the tx power strings)
7. Optimize the Fw flashing logic(base board will boot-up itself after flashed the Fw)

Base: V1.1.4 Feb 15 2022,13:19:59
1. Fix bug built-in MIC feedback to speaker sometimes
2. Fix bug base board some times not booting at power on
3. Optimize ALC algorithm
4. Optimize SWR algorithm, less jumping around
5. Optimize switching power synchronization algorithm, less birdies

Tips:
☆ ALC tricks
a) ALC level equ to 0: over driving, decrease input signal level
b) ALC level equ to 100: under driving, increase input signal level
c) When doing Digi,the audio baseband signals are almost constant amplitude,
adjust the soundcard volume to make ALC level between 20-80 to get good linearity

App: Version V1.1.3 Jan 15 2022,14:48:38
1. Correct the problem of wrong frequency division of 6m (original division: 50.1M~54.0M, modified to: 50.0M~54.0M)
2. The conditions of low-battery shutdown are modified to: battery <10% and voltage lower than 7.3V to prevent low-battery shutdown by mistake when the fuel gauge is not calibrated.

Base: Version number V1.1.3 Jan 25 2022,14:21:03
1. Fix the problem that the RTS signal of the CI-V/CAT port could not control the CW transmission

Tips:
☆ The CAT/CI-V port can be viewed in the device manager, generally called USB-Enhanced-SERIAL-B CH342 (COMx)
Where COMx is the port number, x is a number, such as: COM3
If you find that you can't connect it, you can try to connect via the corresponding port number of USB-Enhanced-SERIAL-A CH342.

☆ How to use N1MM Logger+ to send CW:
Config->Configure Ports, Mode Control, Winkey, etc...
The first page in the pop-up menu [Hardware]
Port drop-down box to select COMx
Radio drop-down box to select IC-7000
Digi remove the tick
CW/Other checkmark
Click Details/Set, and set in turn:
Speed=19200,Parity=N,DataBits=8,StopBits=1
DTR(pin 4)=Always off,RTS(pin 7)=CW
The rest are all defaults, click OK

BASE : V1.1.2 Jan 17 2022,15:44:18

1. In-machine coulometer is enabled to manage battery cell. After the upgrade, the battery capacity, rather than battery voltage, measured by the coulometer is taken as management data. Precautions are as follows:
1.1) After upgrading firmware, please fully charge and discharge the battery for successive 4 times, after which the measurement of the coulometer will be accurate.
After just upgrading the firmware, the error of electric quantity displayed is large before the 4 charges and discharges as mentioned above, so it can be ignored. The charging process shall be kept continuous until the charging instruction indicates it has been completed, which is conducive to the accurate measurement of the capacity by the coulometer.
1.2) The status of the upgraded charging indicator light is as follows:
Flashing: charging
Normally on: charging completed
Off: once the charging option is disabled in the menu, the indicator light will not be off.
1.3) When the electric quantity is below 10% after the upgrade, the battery icon is displayed in red with an empty interior, and the device will automatically shut down.
1.4) Battery voltage is no longer taken as the basis of low power.
2. Parameter adjustment in GEN menu is changed to non-circulating, which can be switch by rotating the large knob to left or right.

8. The problem that label of axis X scanned by SWR does not upgrade is fixed.
9. The bandwidth of first group of filter of SSB is widened to 50-2950Hz(2.9k).
10. The problem of save failure after adjusting the filter is fixed.
11. Indicator string under AGC mode is simplified to AGC-A,AGC-F,AGC-S,AGC--.
12. Indicator string 'FIL-X' of current filter bank is added, which is below VFO frequency.
13. LSB-DIG and USB-DIG strings are simplified to L-DIG and U-DIG.
14. Hand microphone button function is enabled.
14.1) SPCH/LOCK: short press=lock/unlock larger impeller; long press=none
14.2) TUNER/CALL: short press=switch on/disconnect automatic antenna tuner; long press=enable automatic antenna tuner
14.3) XFC: short press=switch VFO A/B; long press=copy VFO from foreground to background
14.4) V/M: short press=switch VFO/MEMO mode; long press=none
14.5) MW: short press=save VFO to current channel number; long press=none
14.6) MODE: short press=LSB->L-DIG->USB->U-DIG->CW->CWR->AM->NFM circulation; long press=none
14.7) FIL: short press=FIL1->FIL2->FIL3 circulation; long press=none
14.8) UP: frequency+stepping position under VFO mode; next channel under channel mode
14.9) DOWN: frequency-stepping position under VFO mode; last channel under channel mode
14.10) F1/F2: allow setting custom functions in RADIO SETTING2
15. Standingwave meter fluctuation under no power and low power conditions is fixed.
16. Maximum output power under external power supply condition is improved.
17. System startup sequence is optimized.
