Features

• Automatic Drone and Operator detection
• Sniffing relevant UDP network traffic
• UDP packet enumeration; including filter predicates
• UDP packet inspection (HEX/Binary) and comparison
• Export as *.pcap
• Import *.pcap
• Export as DUML for further in-depth analysis
• Camera output rendering

Supported Drones

• Mavic Pro 1
• Phantom 3
• Phantom 4 Pro

Theoretical support

Those drones are theoretically supported. However, they do require a delimiter extension which won't be implemented anytime soon.

• Naza M
• Naza M V2
• Phantom 1
• Phantom 2

Supported Platforms

The application runs on all relevant platforms. It has been tested against Windows and Linux. System requirements x86/ARM:

• Windows (7 (Sp 1), 8.1, 10.1607+)
• Linux (Debian 9+, Mint, 18+, Ubuntu 18.04, RH 7+)
• Mac (10.13+)

Prerequisites

1. Install the .NET 5.0 SDK
2. Download FFmpeg 4.2 binaries according to your OS/CPU and place it into the root folder.
3. Optional for Linux (copy function): apt install -y xsel
4. Optional for Linux (video playback): apt install libvlc-dev
5. Optional for Linux (video playback): apt install vlc
6. Optional** for Linux (video playback): apt install gtk-sharp2
7. Optional** for Linux (video playback): apt install libx11-dev

** install when step 4-5 don't enable dji-camera output rendering

Compile + Run Instructions

Switch to the root folder and execute

1. dotnet restore
2. dotnet build
3. dotnet run --project Dji.Ui

Project configurations for Visual Studio 2019 and Visual Studio Code are included.

Release Instructions

For the most easy setup download the latest release and execute dotnet Dji.UI.dll.

Usage Instructions

If you do require any usage instructions, maybe this tool isn't meant for you.

dji-wifi-tools's Issues

Navigation commands

Great effort! Impressive. Feature improvement idea: I see you already get gimbal commands. How difficult would it be to send navigation commands to the drone?

Phantom 4 udp packet sniffing

Hello, I want to use this program to Phantom 4 standard,
but I don't know how to use it.

I had complete install this program, but I can't connect to the Phantom 4 wifi...
How can I connect to DJI Phantom 4 wifi? Or, this program do not need wifi connect?????

Thank you!!

Question regarding compatability with Mavic Mini

Hey,

I'm sorry to ask a question here as it isn't an issue with your code, but I couldn't find any other way to reach you.
In the readme you list compatability with Mavic Pro 1, Phantom 3 and Phantom 4.
I'm curious if you think this would be compatible with the Mavic Mini too.
You cannot connect directly to the drone using a phone, but need to connect the drone through a controller.
However unlike the mavic mini 2 the mavic mini 1 does not use occusync.
I've included some of the details below regarding the wifi config on the controller and the drone.
I'm curious with how this compares with the wifi config you discovered on your drone as described on your blog.
https://www.indie-dev.at/2021/03/15/day-1-getting-started/
Do you think a similar approach to connecting to the AC from a PC, then exposing an AP for the controller to connect to might work here too?
I am a little uncertain as it looks like there is some kind of paired password stored, and it's unclear to me if I would need to do something additional to facilitate the drone/controller pairing process or not.

You did some really great work, I'de love to try and leverage it, to perhaps even control the drone via a laptop :)

PH4 pro 2.0

Hello, I have a Phantom 4 pro v2.0, use OcuSync2.0 instead of Lightbridge.

I want to use this dji-wifi-tools to my PH4 pro 2.0, but I don't know how.
I think PH4 pro 2.0 doesn't use wifi.
(But PH4 pro doesn't use wifi during flying, I think..?)

If you use this tool to the PH4 pro 2.0 , could you explaing me how to use it?

Thank you.
