Mavic 3 Pro (+FCC hack) and 4G dongle

[Axelz]

Their original 4G/LTE dongle does work now in many countries for enhanced transmission on the RC Pro with the Mavic 3's. In the UK however you can not legally use it without a special licence from OFCOM and specific SIM card (although should work with a standard sim). I know drone hacks did mention that the dongle may not work if you have applied their FCC mode hack/firmware to the RC Pro.

Hi,

I have a fcc mod on rc pro installed to use with mavic 3 pro. Now i have installed the 4G dongle on top of the drone but it doesnt work.
I see the toggle for enhanced transmission on the rc pro but it doesnt communicate with the drone. The 4g connection is not possible to put it on. It stays grey/red.
With the mavic 3 enterprise there is no issue at all. Is this because of the fcc mod?

Any tips?

How did you do FCC mod on the Mavic 3 Pro? Did you do this through a mod on the RC Pro? As far as I know there is no FCC mod for mavic 3 pro

The FCC mod was for the RC Pro controller, that's how it worked, not applied to the drone.

I have found a solution to have 4G Enhanced Transmission and FCC mode simultaneously for Mavic 3


After several days of testing I discovered very interesting detail.

It seems that DH emulates that drone is located in US. That’s why FCC is working, and that is why Enhanced Transmission is NOT working because Enhanced Transmission is blocked in states.

But there is 30 minute delay with DJI Enhanced Transmission servers and your remote.

If you switch off your remote and Drone for more than 30 minutes and switch them again, DJI Enhanced Transmission servers check your region again, and if your region is in black list, they block Enhanced Transmission, or if your region is in white list, they unblock your Enhanced Transmission.

If you switch off your remote and Drone for less than 30 minutes, say 28 and switch them again, DJI Enhanced Transmission servers won’t make any check and leave Enhanced Transmission as it was before you switched off your remote and drone.

If you still didn’t get, here is step by step solution.

• You make DH V2 unblock of FCC mode for Mavic 3
• Now your Enhanced Transmission is not working since FCC mode is on
• On the drones name you write DH FCC OFF (that makes you drone to disable FCC mode after next reboot.)
• You switch off your drone and wait at least 30 minutes, it can be days or weeks till your next flight.
• On the location, when you decide to fly you switch on your drone and remote.
• FCC mode is OFF (you disabled it previously in step 3) but your Enhanced Transmission is working.
• On the drones name you write DH FCC ON (that makes you drone to enable FCC mode after next reboot.
• You immediately reboot your drone, and now you have FCC mode ON and Enhanced Transmission working simultaneously.
• After you finish all your flights for today, on the drones name you write DH FCC OFF and switch off your drone and remote.
• After 30 minutes delay you can start all over again from step 5

You can sell your DJI RC Pro and buy another one, max. version 0700. Sincoder will not help you above 0700. At least based on my current knowledge max. is 0700 supported.

The thing is to never upgrade before checking if it works on forums. Also DJI Fly app version 14+ does not allow FCC to work.

hi! still true in Q1 2025 ?
thanks
