Andonstar Wi-Fi Microscope Viewer for PC

A research + reversing + tool born from 20 minutes of late-night -

Streaming the microscope live feed to your PC over Wi-Fi gives you a larger display while still keeping the microscope’s built-in screen available for quick checks.

I've added a script to the repository for both Linux (no_python_windows_script_vlc_curl.sh) and Windows (no_python_windows_script_vlc_curl.bat) that works without Python. All you need is CURL and VLC installed, no additional setup required.

Note: I'm a lazy bastard when it comes to these things, and ChatGPT is my slave, so don't be surprised if there's something silly written here or in the code. It's late, and I'm tired.

✨ What is it?

My Andonstar AD409-Max Wi-Fi microscope stream live video as multipart-MJPEG on TCP 8192 once you flip a MAGIC REST switch.

This repo contains one self-contained Python script that:

1. sends the preview-on command (cmd=3001),
2. opens the 8192 socket,
3. parses MJPEG boundaries,
4. shows the frames with OpenCV,
5. (optional) writes every JPEG to disk,
6. turns preview off when you quit.

No vendor app, no browser, no adb, just Python.

NOTE: I am not sure if this works with other Andonstar. I created this for my AD409-Max, and it works. This was a quick and basic research effort. If you have a different model, feel free to try it and let me know if it works.

Why?

This script makes that possible by relaying the MJPEG stream to your computer and toggling the onboard preview. Note that on the AD409-Max model, the HDMI output is disabled whenever the internal display is active—you can’t use both outputs at the same time.

So this is the easy way to have two displays at same time: one for the microscope and one for your computer.

🚀 Quick start

• Enable WI-FI on your ANDONSTAR microscope from the Settings menu
• Connect your computer to the microscope's Wi-Fi network
• SSID should be something like Andonstar-AD409-XXXX or Andonstar-AD407-XXXX
• Password is usually 12345678 or 1234567890

Dependencies

package	why
requests	send the REST toggle
opencv-python	decode MJPEG & display
numpy	buffer → array bridge

Install everything:

pip install requests opencv-python numpy

---

Then run the script:

python andonstaroswv.py                           # resizable window
python andonstaroswv.py --fullscreen              # full-screen
python andonstaroswv.py --save shots              # dump JPEGs to ./shots

Press Esc or hit Ctrl-C to exit.

---

CLI

option	default	description
ip	192.168.1.254	microscope address
--fullscreen	off	border-less full-screen window
--save <DIR>	–	store raw JPEGs in DIR

---

How does it work?

step	what happens
1	GET /?custom=1&cmd=3001&par=1 → preview ON, port 8192 OPEN
2	send GET / HTTP/1.1 to 8192
3	camera returns multipart/x-mixed-replace; boundary=…
4	script slices JPEG blocks → cv2.imdecode → cv2.imshow
5	cmd=3001&par=0 on exit

---

SHELL commands

curl "http://192.168.1.254/?custom=1&cmd=3001&par=1"   # preview ON
vlc  http://192.168.1.254:8192/                        # or ffplay …
curl "http://192.168.1.254/?custom=1&cmd=3001&par=0"   # preview OFF

Files for fellow reverse‑engineers

• net.pcapng – raw Android APK Wi‑Fi trace
• Ucam_1.9.4.02.apk – original Android APK
• Ucam_1.9.4.02_decomp.zip – Jadx output

Dig in, craft new commands, port the code—go wild.

PORT      STATE  SERVICE
554/tcp   closed rtsp
8080/tcp  closed http-proxy
10900/udp closed unknown
20000/udp closed dnp
MAC Address: 98:03:CF:26:D3:FC (Shenzhen Bilian Electroni...)

After MAGIC REST switch, the device opens port 8192 for MJPEG streaming:

PORT     STATE SERVICE
80/tcp   open  http
443/tcp  open  https
3333/tcp open  dec-notes
8192/tcp open  sophos
MAC Address: 98:03:CF:26:D3:FC (Shenzhen Bilian Electroni...)

Btw, 3029 cmd returns the current Wi-Fi SSID and password:

curl "http://192.168.1.254/?custom=1&cmd=3029"

<?xml version="1.0" encoding="UTF-8" ?>
<LIST>
<SSID>Andonstar-9803cf26d3fc</SSID>
<PASSPHRASE>12345678</PASSPHRASE>
</LIST>

TO-DO

• Investigate why the Wi-Fi disconnects after some time. It might require sending a keep-alive command, implementing a sleep mechanism, or exploring other potential solutions. use powershell -ExecutionPolicy Bypass -File .\wifi_force.ps1 as a crap-workaround.
• research & document all commands
• check if preview off command works
• test more Andonstar models
• add more features to python script like mp4 recording

Tested

• Dreg's AD409-Max
