ARES SOFTWARE — DJI Specialized Diagnostics & Repair Technology
Replaced the camera or gimbal on a DJI Mini 4 Pro? This Windows app walks you through the checks that follow the repair: it confirms the aircraft is connected over USB, asks the gimbal, camera and flight controller to report their firmware versions (read-only), runs the guided gimbal calibration and records your DJI Fly checks in a saved repair report.
Error codes
-
40011: Gimbal error shown in DJI Fly after gimbal or camera work. Addressed by the guided Joint Coarse and Linear Hall calibration when it comes from calibration being out of date; if it remains after both steps pass, the cause is outside calibration.
How it works
- Connect the powered Mini 4 Pro to your Windows PC with a USB data cable and open the app.
- Click Check USB connection, then Check modules (read-only: nothing is written to the aircraft).
- Click Run gimbal calibration. The app runs the two calibration steps (Joint Coarse, then Linear Hall).
- Do the DJI Fly checks, mark each one, and save the repair report.
What you get
- Windows app built for the DJI Mini 4 Pro only (the model is fixed in the app), version 0.1.1
- Opens directly: no activation code, key, account or sign-in
- The calibration engine and USB runtime are included; nothing else to install
- Step-by-step user guide with real Windows screenshots (installation, USB driver, each step, results, troubleshooting)
- Saved repair report (text and JSON) for each job
- Third-party licenses and the engine's complete source code (GPL v3) in the package
- Email support from Ares Acres (brandon@aresacres.com)
What you need
- A Windows 10 or 11 PC (64-bit). Nothing else to install.
- A USB data cable (not a charge-only cable).
- Possibly a one-time USB driver setup; the guide shows how, and the app tells you if it is needed.
- DJI Fly on your phone or remote for the final checks.
Delivery and support
- Digital download only: nothing is shipped.
- After purchase Ares Acres emails a download link for the Mini 4 Pro package (a ZIP file with the app, the user guide and the license files).
- Unzip it to a folder on your PC and double-click AresMini4ProCameraGimbal.exe. Windows SmartScreen may ask you to confirm the first start (More info, then Run anyway).
- Support: email brandon@aresacres.com with your order number and the exported report or support log.
Please read before buying
- No guarantee that error 40011 clears. If both calibration steps pass and the error stays, the cause is outside calibration (a damaged part, a cable, or a camera and main board that do not match).
- It does not pair a replacement camera to the aircraft's main board. That still needs DJI service.
- It does not update or change firmware and cannot fix damaged motors, cables or circuit boards.
- Hardware not yet verified by Ares: it passes Ares's automated Windows, simulation and failure-handling tests, but it has not yet been run on a physical Mini 4 Pro by Ares.
- For the DJI Mini 4 Pro only. Not an official DJI product.
Questions
Does it fix the error for sure? No. It runs the gimbal calibration. If error 40011 came from the calibration being out of date after a repair, calibration is the step that addresses it. If the error remains after both steps pass, something else needs repair.
Does it pair a replacement camera to the main board? No. Camera-to-main-board pairing is not part of this app. It checks the modules over USB (read-only), runs the gimbal calibration and records the DJI Fly checks.
Does a PASS in simulation mean my aircraft is calibrated? No. The built-in simulation mode (used for Ares's own testing and the guide's screenshots) is clearly marked SIMULATION and sends nothing to a drone. Only a PASS with your aircraft connected means the calibration ran on it, and even then it is not proof that the hardware is sound.
Has it been tested on a real aircraft? Not yet by Ares. Every release passes automated Windows tests, a full simulation and failure tests (disconnects, time-outs, wrong answers), but physical Mini 4 Pro compatibility is not yet verified.
Do I need internet, a key or an account? No. Ares delivers the Windows application directly. It opens without an activation code, account or internet connection.
How do I get it? After purchase Ares Acres emails the download link for the Mini 4 Pro application and its guide.
Will it work for another DJI model? No. Each app is built for one aircraft. This one is for the DJI Mini 4 Pro.
