We’re sorry to hear that you’re having trouble, especially after you’ve already contacted support and the Discord server and have gone through the recommended troubleshooting steps. We understand this must be frustrating.

The Mobula7 O4 is designed to work with the DJI O4 Air Unit. For connection with a DJI FPV Remote Controller, specific Betaflight firmware flashing and configuration are often necessary. This process typically involves reflashing the Betaflight firmware to include “SBUS” protocol support, importing the factory default settings via the CLI command, and then adjusting Betaflight settings accordingly. Generally, no hardware modifications to the flight controller should be needed for this.

Since you’ve already attempted the recommended solutions, we’d like to help you resolve this. Could you please provide us with a bit more detail about the steps you’ve already taken? Specifically, it would be helpful to know:

  • Which model of DJI controller are you using?

  • Have you been able to confirm if the Betaflight firmware was reflashed to include SBUS support?

  • Were you able to import the factory default CLI settings and adjust the Betaflight UART and receiver settings as per standard Happymodel instructions?

  • Are you seeing any specific error messages or LED light patterns on the Mobula 7 O4 or your DJI controller?

  • Can you include a photo showing how the 04 is connected?

In some cases, issues with the DJI O4 Air Unit itself might necessitate sending it for warranty service. It’s also a crucial step to ensure the O4 Air Unit is properly registered and its firmware is up to date using the DJI Assistant (Consumer Drone Series) software.

Once we have a bit more information, we can explore further options, which may include more specific troubleshooting, or if necessary, discussing warranty options or a potential return/exchange if the product is determined to be faulty.

We appreciate your patience and cooperation as we work to get your Mobula 7 O4 flying.
