UPDATE!
The debug port is a legacy step that ADB no longer strictly requires!
The latest adbconnect script has been working wonderfully, as the goal is
always to reduce everything we do on any computer to a single quick step.
But... the strangest thing happened earlier today...
I found out that the debug port is a legacy port. It's not actually needed.
It was almost like when I found out that gravity isn't actually a force.
And that everything moves at the speed of light through curved spacetime.
So gravity is due to the curvature of time (mostly) & not to space curvature.
Yet, everyone (including me) always thought that gravity was a force.
And that it was due to the curvature of space (mostly) and less so of time.
It's not. And the adb connect step is also not needed either.
All we need is the adb pairing step.
How do I know this (without being a window washer falling off a roof)?
I ran adbconnect but I accidentally mistyped the debug port.
Yet the desktop still connected over Wi-Fi to adb and to scrcpy mirroring.
Huh?
Turns out, the debug port is ... um... er... optional.
Who knew. Not me. Now I do.
All we really need is:
a. Pair over Wi-Fi
b. Run adb tcpip 5555
c. Connect to 5555
d. Launch scrcpy
Pairing port = authentication
Debug port = optional first-connect helper
Once pairing succeeds, ADB has a trusted identity token for the device.
USB connection between phone & desktop:
a. Already trusted
b. No pairing needed
c. No debug port needed
d. We can immediately run adb tcpip 5555
Wi-Fi connection between phone & desktop:
a. We must pair
b. Pairing gives ADB the same trust token USB normally provides
c. After pairing, the debug port becomes optional
Because Wi-Fi pairing replaces the need for USB.
And once paired, the debug port becomes irrelevant.
The debug port is a legacy step that ADB no longer strictly requires.
Yet, when I commented out the debug port, the script logic unexpectedly
broke when re-launching scrcpy (when it was already running). Huh?
Turns out once paired, the PC is permanently authorized to connect to that phone over Wi-Fi, regardless of what port is used next (until rebooted).
In addition, I added logic to detect if scrcpy is already running & if so, to use the existing running connection instead of killing/restarting it.
:: adbconnect.bat (Automate Android-to-desktop Wi-Fi adb/scrcpy connections)
:: Solves two problems when connecting a desktop to adb/scrcpy for Android.
:: 1. Eliminate all useless random-security steps in a Wi-Fi adb connection
:: 2. Eliminate the useless scrcpy console window which just takes up space
:: v1p8 20260619
:: a. The debug port user-input query was removed
:: b. And the pairing to TCP/IP flow was simplified as a result
:: c. Plus, detection of scrcpy already running was added to prevent scrcpy

:: (ADB pairing only needs to be replenished after the phone has rebooted.)
:: v1p7 20260615
:: Removed the requirement for the "no-console" vbs script
:: by injecting the necessary commands into a temporary file
:: This is the cleanest way I can think of to eliminate the console.
:: v1p6 20260614
:: Called the vbs "no-console" script that comes with adb.
:: If the script isn't there, then it defaults to the old method.
:: The problem is getting completely rid of the scrcpy console isn't working.
:: These are the known scrcpy console-hiding methods:
:: (a) cmd /c start "" /min (minimizes the console)
:: The console is not hidden. It's just minimized.
:: (b) cmd start "" /B (background launch of detached console)
:: This detaches scrcpy from the batch console
:: (c) adb default VBS no-console wrapper (fully hidden window)
:: Default GUI-subsystem scrcpy launch (so no console is created)
:: CreateObject("Wscript.Shell").Run strCommand, 0, False
:: (d) Kleebauer ShowWindow() controller trick to hide the batch console
:: showwin.exe 0 SW_HIDE (Hides the batch console)
:: (e) Powershell ShowWindowAsync (similar idea to Herbert's ShowWindow()
:: Add-Type '[DllImport("user32.dll")]
:: public static extern bool
:: ShowWindowAsync(IntPtr hWnd, int nCmdShow);'
:: Here is the original scrcpy-noconsole.vbs that comes with adb
:: strCommand = "cmd /c scrcpy.exe"
:: For Each Arg In WScript.Arguments
:: strCommand = strCommand & " """ & replace(Arg, """", """""""""") & """"
:: Next
:: CreateObject("Wscript.Shell").Run strCommand, 0, false
:: v1p5 20260613 Added query asking for the LAN IP address of the phone
:: Reordered comments to allow the current version to be obvious
:: v1p4 20260612 minimized the scrcpy console (but it's still there)
:: using cmd /c start "" /min (minimizes the console only)
:: The only known choices are
:: (a) Minimized console-subsystem launch (cmd /c start "" /min)
:: (b) Background detached launch (start "" /B)
:: (c) Hidden GUI-subsystem VBS launcher (no console created)
:: (d) External ShowWindow() console-visibility controller (Kleebauer trick)
:: (e) PowerShell ShowWindowAsync console hider (similar to ShowWindow())
:: v1p3 20260612 moved the pipe outside the FOR command for reliability
:: v1p2 20260611 further reliability improvements added to v1p1
:: Use separate retry counters for pair/connect to avoid loop
:: interference (ATTEMPTS_PAIR, ATTEMPTS_CONN)
:: Added fail-fast with clear error codes and user hints after retry
:: exhaustion
:: Added a detection of the device id after initial connect
:: (handles ephemeral adb ports like 192.168.1.4:54321)
:: Use DEVICE_ID for subsequent -s tcpip command (quoted)
:: to avoid parsing issues with colons
:: Fallback device-id lookup when initial pattern match fails
:: (robust parsing of "adb devices")
:: Consistent quoting of %ADB% and device identifiers to avoid
:: CMD parsing errors
:: v1p1 20260611 reliability improvements added to v1p0
:: Added better device lookup (skip header,ignore blanks,avoid false matches)
:: Added retry logic for adb pair & adb connect (for when phone not ready)
:: Improved polish (consistent quoting, stable scrcpy launch)
:: v1p0 20260611 converted adbconnect.vbs to adbconnect.bat
:: Connects desktop & phone over adb & mirrors phone on the monitor
:: No USB cord is used in this process as it's all done over Wi-Fi
:: Should work even if either the PC and/or the phone is rebooted
:: The script will ask only for the minimum amount of data needed
:: Change the phone static IP address as needed to fit your LAN IP address
