Add support for using DJI Developer SDK directly (Mini 4 Pro support + remove manual waypoint replacement hack)

[spwoodcock]

Issue

• Until now the DJI Developer SDK did not include the Mini 4 Pro (specifically the mobile SDK
• We had to use a workflow like:
  • Create a mock flightplan on device.
  • Create a waypoint flight via drone-flightplan module.
  • Replace the mock flightplan with the newly generated one, by manually connecting the controller and replacing the file.
• The DJI Developer SDK now supports the Mini 4 Pro, so theoretically a workflow like this is possible:
  • Generate flightplan via drone-flightplan module directly on mobile device (via drone-tm website).
  • Upload the generated flightplan directly to the drone using mobile application.

Possible Solutions

1. Use a third party app with SDK integration already in place!

• Spexi already supports this.
• Litchi (but, as of 21/07/2025, I'm not sure a version of Litchi for DJI mobile app has been released with support yet, however, the beta Litchi pilot app may have support.

We would need to ideally import the flight plan into the third party app, then control the drone / use the flightplan from within the app.

2. Create our own app to interface with DJI SDK and directly fly the drone.

• While this isn't ideal to have to maintain, it does open the door to interface with other drone SDKs in future, all within one app.
• It does add extra risk / requirements for stringent testing, as we could crash drones!
• We would need to take into account which controller the user has (RC2 or RC-N2), plus the drone model flying.
• We also need good in-house mobile dev skills, which aren't currently there.
