I live near Seattle, WA. I purchased the Mini 3 Pro with the RC a couple weeks ago. The manufacture date on the box was 07/22. I had all the issues the OP described here. Stuck in CE mode, no option to change bandwidths, very poor range etc. The furthest I was able to go was about 400m. Poor transmission typically started around 250m. This was in a fairly open area with a few tall trees but nothing major. Changing altitude made little difference. For perspective, I have the 1st gen Mavic Air and can fly it well over 1000m in the same area without any issues. I tried all the suggested fixes- Upgraded firmware, downloaded DJI assistant and did a factory reset on both the controller and the drone, rolled back to previous versions of firmware and tested them, covered drone and delayed satellite connection etc. Nothing worked. I returned for a refund. This appears to be a major issue for a small amount of these drones and it’s unacceptable to me that DJI can’t seem to figure this out.

Thank you for your update. I took the same route and upgraded to a Mavic 3. I should test it today at the same areas that I had previous issues with the Mini 3 Pro and let see the results / differences in range.

Updating this tread! I finally received my Mavic 3 today and I was able to fly over the same areas where I previously had transmission issues with the Mini 3 Pro. I hadn't any single signal drop at all with the Mavic 3, no lost of connectivity, no broken live streaming image, before I couldn't go over 300 letters without loosing connection between the aircraft and the RC controller.

I am using the RCN-1 at this time.

My assumption and conclusion is that there is an issue with the Mini 3 Pro vs Controller or both. If DJI Support didn't messed up back few weeks ago and sent a RCN-1 instead of another RC controller I would be able to test at that time.

I hope DJI acknowledge once for all that there is batch of devices that are not functioning correct and concentrate themselves on fixing these issues.

For those who have problems with the range, the following tips.
1. it does not have to be the transmitter (RC or RC-N1), it can also be the Mini 3.
2. check the alignment of the controller to the drone (compass, green confirmation).
3. fly manually in 5GHz mode.
4. look for someone in your area who also has a Mini 3 and let him test in his own place.
If in doubt, report the Mini 3 to DJI as a case.

With the CE version are easily 3km distance without loss of reception possible. Depending on the building and interference, it is already after 250m end.
Likewise, a tree with foliage between you and the drone can greatly impair reception.
But, if you test properly and then no range is possible, complain and expect a replacement.
Mine is made in May,22 and makes no problems. RC was already exchanged, range 3.1km to 1 dash indicator fluctuated and I decided to shoot.

Thank for your feedback. I went through 2 different Mini 3 Pro exchanges and numerous tests with DJI support before giving up on the Mini 3 Pro.
What explains the fact of having the Mavic 3 flying the same exactly área with amazing performance without any communication losses them?

My controller did not give the option to select different bandwidths. It was just stuck in Auto and everything else was greyed out. This issue has been observed by other Mini 3 users as well. Orientation to the drone was not the problem either. As stated in my previous message I have zero issues in the same area with my 1st Gen Mavic Air which was not know to have great range. There’s no reason a brand new drone with Occusync 3 should have less than half the range of my aged Mavic Air using wifi transmission.

Thanks for the update! This is undoubtedly a Mini 3 issue that only seems to affect certain models of the drone or controller or both. I’m leaning towards just getting the Air2s. The Mini 3 has some great features I would love to use but a rock solid connection is more important to me. Experiencing poor transmission at 250m makes the drone largely useless for me. I suppose I could try ordering another one with the N-1 but I don’t really want to hassle with returning again. I’ll update here if I do decide to go that route.

For me, this is a personal feeling, the Mini 3 pro itself has the problem or sometimes double with bad working RC. Also posible, that the receivers / transmitters are not well balanced.
Don´t know.... Push it back to DJI.
Lot of Users also very happy (include me), so it can´t be a major general issue in design.
Hope the best for you all.

Since DJI outsource parts from different vendors including these logic boards in China I believe that there is a specific batch from a specific vendor that is causing these issues, this would explain why this problem is not replicated to everyone.

Is that just a guess? or do you have some info that we can see to support this? I think most if not all of the parts are made off-site. There is nothing to suggest that they used different companies for the same part though, hey, i could be wrong but i haven't read anything that suggests this.

I am in a CE country and I have a June or July model, i know that it can do 5.5km at 29m high in a rural setting. To achieve this, the RC and the drone must be 100% perfectly aligned. If this isn't so then it will drop the signal and within 3 seconds it's doing an RTH. Its not like other DJI drones, its far less forgiving, signal wise.

Yes, there are so many variants but the fact of testing a Mavic 3 unit over the same exactly area with not a single transmission drop proves the point, and using a inferior controller as well. Also the Mavic stays in FCC mode all times during this test, the Mini 3 Pro didn't even have the FCC mode available in this area.

My assumption with the vendors / parts issue vs defective batch  comes from a factoring engineering quality control process which is my background and field of work. There is an elimination process based on threshold (in this case the customer service feedback determine the level of threshold) and it would trigger DJI investigation on this problem and many others related to their products, specially with the trend of launching products including software / firmware updates not ready for prime time.

This maybe part of China culture and I may be missing something, we will never know....

Unfortunately, I'm entering the chat with the same problem. I'm also located in California and have the latest firmware.  Please let me know if there's anything I can do.  See link below for details:

I see you live in HB as well. I had so many transmission issues with the Mini 3 Pro flying over the Terra Bella area that after numerous interactions with DJI Support, aircraft and RC replacements, I sent everything back and used my refund towards a Mavic 3 which I am extremely happy about it. Below is the video of the Mavic and also 2 videos I recorded showing the transmission issues with the Mini 3 Pro few weeks ago. This issue was never resolved.

Hi, there.
We are sorry for the inconvenience caused.
We will check your case and see how we can do better with this part.
Besides, if there is anything else that we can help with, please let us know.

Same issue air2s 400 mtr connection problems how to solve this

Why are you upset dji sent you the rc controller and not the rcN1? The rc controller is worth $309 while the rcN1 is like $60 on ebay. I am confused here. I have tested the rc controller vs the rcN1 and my results was the rc controller have twice the range in my testing on dual channel. My rc controller was able to get 15,000ft before losing signal. While the rcN1 only get like 7400 ft. Your controller will automatically switch to FCC or CE, depending on your location.

I get the same distance give or take a few feet with both the N1 and the DJI RC and that is around 5.5km in CE mode, there's no power difference in the RC's.

For matey that says the Mavic 3 goes further, the reason it can go further is the power difference, i believe its O3+ whereas the Mini 3 Pro is only O3. but there's no reason why they would see such a low distance with the Mini 3 Pro unless they were not flying within the prescribed parameters so as to attain the best results.

This Mini 3 Pro exceeds the max distance i have managed to get with the Mini 2.

As a side note, i have also tried the RC Pro and on the same day testing with the DJI RC and the RC Pro was about 2km less than the DJI RC, suffice it to say that the RC Pro was sent back as it had to have been faulty.
