"Downlink data connection lost for nnn seconds"

Current Worldwide Frequency

RareCommon

Severity: Low Risk

   Low severity, impact on safety is likely not significant

Description

This message shows up when the remote control got partial or no flight data from the aircraft for more than 1 second, which means the metadata downlink had issues.

It is possible that during this time there is a sense of full control of the aircraft via the remote as well as clear video, however, typically the video gets choppy and the remote controls may have some delay.

This is typically an indication that the aircraft was flying in a high interference area or that distance was a negative factor. In these conditions the aircraft is at higher risk of initiating the Return-To-Home function.

If RTH is triggered then signal regained normal controlled flight can be resumed.

Once the RTH is activated and you recover the video stream, you can deactivate the RTH and regain manual control.

I'll try this next time it happens. It's happened 4 times now over the last year, and I've been able to fly the M2P back, land and power cycle it, restoring the link. I'm hoping this will work, triggering RTH to recover telemetry/video, and be able to continue on without having to land/power cycle.

Yes you can go back. Just install DJI assistant 2 and plug your device into your computer (remote controller/your dji drone/dji goggles) Then it shows you what the current firmware is and the option to downgrade. Hope this helps :-)

Hi. With the new update v01,01,0800 for the Dji Mavic Enterprice Dual i cant downgrade the firmware. Only do the update/Refresh. Il do a new refresh of the firmware to see if it helps.

I received the msg. in the flight record that communication with the RC was lost for 25 seconds. I was flying the Mini using Dronelink to fly a mission. At just about the same time I received an error msg. saying, "Camera Start Capture Failed". I was not using the camera I was using the video. Anyone have any idea whether these two are related and if so what does the camera msg. mean? I looked back at the mission and find no errors.

Hi experts.
Is it possible to get (in the flight data) the frequency channel in which the interference occurred? Thanks

Estimados, perdí la señal con el equipo por un minuto y medio, la pantalla totalmente negra y no tenía ningún control con el equipo, luego del tiempo mencionado se volvió a conectar, el dron estaba en la misma posición, no activo tampoco el RTH. Al revisar el FlightRecord se sale este error. Algún comentario de que puede haber sido, todas las demás condiciones normales, el dron a 700mts de distancia y 50 mts aprox. de altura, batería en 89%, 2.47 minutos de vuelo. Gracias

We got this issue right after updating controller, drone and an app. Has DJI fixed this? Or is there any turn around to this?

DJI Matrice 4T – Repeated Downlink Data Connection Lost (13–25 Seconds) + Remote ID Controller Location Errors

I'm looking to see if any other Matrice 4T operators are experiencing similar issues.

Aircraft: DJI Matrice 4T
Controller: RC Plus 2 Enterprise
Firmware: Current (will verify exact versions if needed)
RTK: Enabled during affected flights (using network RTK corrections)
Location: Multiple flight locations and environments

Since purchasing the aircraft, we have experienced repeated AirData notifications indicating:

"Downlink data connection lost"

The interruptions have ranged from approximately 13 to 25 seconds and have occurred on multiple flights.

Examples include:

13.5 second loss
21.4 second loss
18.4 second loss
19.1 second loss
22.5 second loss
24.7 second loss

What concerns me is that these events have occurred at very different distances from the controller, including:

71 ft
123 ft
967 ft
1,855 ft

In several cases, the aircraft was hovering or flying slowly when the event occurred.

In addition, the downlink-loss events are frequently accompanied by:

"Remote ID broadcast error. Failed to obtain remote controller location"

On one flight, the aircraft entered Return-to-Home immediately following the disconnect event.

The aircraft remains controllable after the connection is restored, but these interruptions are concerning, especially for an enterprise platform.

Questions for other Matrice 4T operators:

Have you experienced similar downlink-loss events on the Matrice 4T?
Have you seen the Remote ID error stating "Failed to obtain remote controller location"?
Are you using RTK/NTRIP corrections when the issue occurs?
Did firmware updates or firmware refreshes resolve the problem?
Was the issue ultimately traced to the aircraft, controller, RTK connection, or something else?

Any feedback, troubleshooting steps, or known fixes would be appreciated. I am currently gathering logs and trying to determine whether this is a firmware issue, controller issue, RTK/network issue, or potential hardware defect.

Thank you.

Hi Mark, I've had a similar issue with an M4TD, it occurred when moving between video and still-camera options. Did your fault persist or has it corrected itself now? Upon checking Airdata logs we get "Downlink data connection lost".
