jtxBoard on a desktop (over adb and scrcpy)

[mcastillof]

Hey, I just wanted you to know that jtxBoard may be used on a desktop (GNU/Linux, MACOS and Windows) by using ADB and a program called scrcpy.

Scrcpy is a tool that "mirrors Android devices (video and audio) connected via USB or over TCP/IP, and allows to control the device with the keyboard and the mouse of the computer. It does not require any root access."

When using scrcpy, you probably will want to use a script to optimize the experience, like change the DPI, change and lock rotation to landscape. This is the script that I use, you should change rotation, density and resolution settings, before and after the scrcpy command, also when finishing your session with scrcpy always close its window to allow the execution of the last commands to go roll back the temporal configs:

#/bin/bash

#unlock phone
#unlock_pocophone_x3_pro.sh
sleep 1

# lock rotation
adb shell content insert --uri content://settings/system --bind name:s:accelerometer_rotation --bind value:i:0

# set landscape rotation
adb shell content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:1

# change density
adb shell wm density 308

# increase resolution
adb shell wm size 1300x2400

# mirror screen
#--legacy-paste 
#you may need to setup the physical keyboard to your layout in your phone by going to Settings/System/Language & input/Physical keyboard
scrcpy --stay-awake --window-height=1080 --window-width=1920 --keyboard=uhid #--forward-all-clicks

# return resolution
adb shell wm size 1080x2400

# return density
adb shell wm density 440

# return rotation lock
adb shell content insert --uri content://settings/system --bind name:s:accelerometer_rotation --bind value:i:1

Clipboard is shared between your desktop and your phone, so ctrl+c and ctrl+v works fine. I still need to investigate which are the best arguments for scrcpy for mouse clicks

You may need to setup the physical keyboard to your layout in your phone by going to Settings/System/Language & input/Physical keyboard. The physical keyboard option is only available when scrcpy is running.

For unlocking (pattern) automatically the phone I used "adb shell getevent" to record the pattern as I swiped it on the phone screen and "adb shell sendevent /dev/input/event4" to simulate it later.

Have fun!
