It appears that the P4Pro RTK can no longer cache maps for use in areas with no cell coverage. Per my conversations with DJI support, they are aware of this but give no expectation of a fix, and suggest planning the flight in advance and flying with no map coverage on site.



Here is my conversation with DJI support:

Dear Jack,

Thanks for getting back to us.

We do apologize for the inconvenience that caused to you. It is just the Phantom 4 RTK that has this map issue. We would recommend you to either plan the mission in advance, then fly in areas that have no cell service or you can use the SDK remote controller with Pilot app: DJI Pilot - Download Center - DJI

Then you can use the offline map in the Pilot app to fly in areas that have no cell service. For the purchase and price inquiry of the Phantom 4 RTK SDK remote controller, or if you want to test the SDK remote controller, we would recommend you to contact our enterprise dealer, and here is the link for you to look up the contact information of dealers around you: Enterprise Dealer - Where to Buy - DJI

Any further questions, please feel free to contact us. We're always here to help.

Thanks for choosing DJI. Have a nice day and stay safe!

Best Regards

I am absolutely not satisfied with the answers I have received. Apparently DJI has made it impossible to fly in areas that have no cell service. Quite often I design and fly autonomous missions in the field where there is no cell service and DJI making it impossible to cache maps for offline use is unacceptable. I would have not recommended my company purchase the P4Pro RTK if this was the case originally, but it is even more upsetting that after DJI has the money they remove the ability to cache maps making the drone useless for some necessary tasks.

Has DJI removed the ability to cache maps for offline use for all models of their drones, or just the P4Pro RTK?

Will DJI offer the SDK controller so customers can utilize third party apps that will allow map caching for use in areas with no cell coverage?

Please offer some assistance with this matter.

Dear Jack,

Thanks for getting back to us.

I am sorry for the late reply as I was out of office in the past two days, and we do apologize for the inconvenience that caused to you as we have changed the map service provider in DJI App. If there is no network service at your workplace, we would recommend you to create a flight mission. You can plan the mission first, then take the drone there to execute the mission directly.

Any further questions, please feel free to contact us. We're always here to help.

I still have not received an answer on how I should fly sites that have zero cell service since the maps will not cache on the P4Pro RTK.

Please advise, getting behind on monthly site quantity measurements.

Thanks for the response, you said to keep the firmware up to date, and the remote connected to the internet.

However you did not address the issue I am facing when I need to fly a job site in an area where cell service is not available. In these areas I cannot keep the internet connection when using the remote.

We are a road and bridge construction company and work frequently in very rural areas with no internet service available, but fly projects on a regular schedule for progress and quantities.

Most of my processing is PPK so disabling the RTK is not the issue, just not having map access in areas with no cell service.

Are you saying that I can no longer use the P4Pro RTK drone in areas where there is no internet?

We purchased this drone a year ago and it has been a great asset and I hate to see the investment go to waste because you changed to a map service provider that does not allow the drone to perform as originally advertised.

Please advise how we continue to fly in areas with no cell service.

Thanks

Dear Jack,

This is Nick from DJI Technical Support.

We are grateful to assist you with your concern and really want to help further. I just received the message from another technical team and understand that you have a question about not getting the map to pull up.

For this issue, please kindly note that due to some reasons, we have to change the map service provider in DJI App. And because of the copyright restriction from the new map service provider, the map could be loaded online only.

For the problem you are facing, please follow the instruction below to fix the problem you are facing.
1. Please make sure the firmware of the drone and remote is up to date.
2. Please keep Internet connection when you are using the remote.
3. Please make sure the drone is on an open place so it can pick up enough satellites. So it can locate its location.
4. If the drone has a RTK function and the RTK is connected, please disconnect it first. After the map is loaded, reconnect it. While using RTK service, the app will not load the map.

After doing this, the app will request map from the server and it will show at the background. Our engineers know this is a big inconvenience and they are still looking for another solution. Please consider it as a temporarily solution.

DJI engineers have determined the cause of this issue. Due to the copyright restrictions, the remote sensing map cannot be cached to a local storage. We recommend that you connect the remote controller to the network to load the remote sensing base map during the flight route planning or flight. Also, you can choose an electronic map as the base map for flight route planning and flight operation. Thank you for your understanding.

Any further questions, please feel free to contact us. We're always here to help.

Thanks for choosing DJI. Have a nice day and stay safe!

Best Regards
Nick

@Harleydude do you have any input on this situation? I know you do mapping without connecting to the internet from your recent post.
 
I got additional info today that DJI removed Mapbox as a map source on this drone, which only leaves Amap, and Amap does not allow caching for offline use.
Other DJI products still use Mapbox, wonder why they removed it from an enterprise level drone with no good work around.
 
As always, the answer to every question I've ever answered in this forum is the same; "Legacy firmware. Legacy software." I'm not sure where your bottleneck is. I would guess software (because that is where map caching is stored), but it may have something to do with firmware, as well. For instance, the legacy software that WORKS with the P4P may require legacy firmware.

Use DUMLdore to roll back your firmware. Rolling back software in an iPad is much more complex, and I won't get into it here.

Here are the versions that work on my P4P (notice map cached in the background):

This information gets you 90% there. You'll have to do your own research for the remaining 10%. This effort will be the poster child for diminished returns, as most of the work, time, energy and effort will be spent figuring out the remaining 10%. It's not an exact science. So what works for some doesn't work for others. Hence, the reason I tell you to figure the rest out on your own. Look into using CharlesProxy to gain access to legacy software. I've never rolled back iPad iOS because I've never had to because I never allowed any of my 5 iPads update. They are all stuck on the iOS they came with (a hack within itself)(see above screenshot).

Good luck.
