I've seen mention of checking if the RC is on US mode(FCC), but have not seen the method to get there to check.
Checking if on US version
- Thread starter uxodas
- Start date
Sounds correct, at start with only the RC it shows 11 channels and when I turn on the Spark it switch to 13 channels.
Does that change with the .DJI.configs FCC patch and you get only 11 channels in 2.4 with the Spark connected to the RC?
Back from the US and I'm experimenting with that patch but not sure if it works.

Hardware ? Do you mean firmware ? I'm all ears ;-)
So I've done some experimenting and found that :
1. Indeed .DJI.configs does not appear to be working with the Spark on .500. I alwways get 13 2.4Ghz channels, whether in direct or RC connection.
2. Running the patched 4.4.13 I got a prompt to change the WiFi region upon first connection, I clicked ok and when it came back I was indeed limited to 11 2.4Ghz channels
3. Running the latest (non-patched 4.4.15) I get a prompt to change WiFi regions that I cancel and I still get the 11 2.4Ghz channels only, so all good it seems.
4. It started to rain at the parc so my testing time was limited but it did complain about weak signal in 5.8Ghz at 265 meters (LOS) with the RC so maybe the RC's power is limited even though the Spark's isn't ? Other than flying as far as possible I'm not sure how to check for that ?
PS : My phone (Lenovo P2 running N/7.1) must not accept the "outdoor 5.8" channels because I cannot connect directly (doesn't see it) to the Spark without a WiFi reset (9 second beep). What's weird is that it worked fine when I was in the US so I suppose it's doing some auto-detection. I can't see any regional setting for WiFi but I am rooted so maybe there's a way around this, a handy .apk possibly ?

I am not dealing with software/firmware mod as I don't need them and I don't need to add such risk. I can reach more than 1000 meters for both band in non urban area and it where I mainly fly.
1, 2, 3. No idea
4. You need to found an area which is really clean from interference so you can compare between flights over time. Also there should be no other device using bluetooth or wifi with or near you.
Regarding you PS, I had the same with a Samsung S6, Tab S2. Some others also with S7. With my iPad mini 4, there was no issue to use these special wifi channels (low power mode) here in Europe. At my surprise my new S8 has also no issue to use them, so it is not a android / ios story. These channels are normal wifi in US and special in Europe. DJI decided to use only these one instead of another set that would satisfy US and CE.
Detection of country can be also linked to the SIM card or the cell provider.

Ok, back to original question. What I was referring to is, I'm app, there is a way to actually see "version" to see it it is US and a value of 0.
That process is what I'm interested in.

Not sure what you mean. The way is as Marcocappe indicated at post #2.
It seems that this is what they are doing yes as I found a log file by accident (with ES File Explorer) that had references to MCC and I also found another one with references to NFZ.
Will try some more testing when the weather clears up.
1000 meters in 2.4 and 5.8 ? Well I suppose Switzerland does not fall under the CE umbrella then ;-)
In Switzerland the CE mode is applicable, not FCC. It would have been almost 2000 meters I would say. But controlling the Spark through wifi at 1000 meters is already an issue as with wifi the conditions can change very quickly. Flying near a house and then somebody there start to watch a video on his mobile using the house wifi and the Spark link could be lost. Having a little more power will not change that flaw. You can go at some distance with the Spark only if there is nobody using wifi and bluetooth in the area.
CE mode and 1000 meters with Spark - I wish I could reach 500m with 2.4Ghz...
Did it work with .400 for you?

With Windsurfers reflectors I got one time 1500 meters, but it was not in an urban area and I think nobody was using their wifi in the nearby villages. For sure Bluetooth was off in all devices.

Wish I could get better range out of mine, 120m is the best I have managed for video range, 160m for craft range before RTH enabled.

Yeah that's really not much :-(
@Pac : .500/AC and .300/RC
Now it's possible that the .DJI.configs file only works once (or has to be write protected) because when I fired it up yesterday it did say something about the "wrong wifi region" and not knowing what it meant at the time I accepted. Maybe that file had switched it to FCC after all. Never got that message again until I fired up the modded 4.4.13 and got the WiFi switch that I accepted and have cancelled ever since with stock 4.4.15 ;-) Other than the 180° Pano there are no new features are there ? I think the smoother gimbal rotation is from the RC directly ?
@Dronason - Switzerland must have different rules for 5.8Ghz because it loses connection at ~300 meters in the EC as I found during my testing today!

You should have either a defective unit or some interferences.
There is no difference at my knowledge in Switzerland compared to Europe for the channels 149-165 that DJI uses (List of WLAN channels - Wikipedia).
In any case, for a fly with the RC, the phone/tablet has little influence to the distance that can be achieved, so remain RC and the Spark. The only way I know to define if the Spark is in CE or FCC mode is the number of channels in 2.4G. If it shows 1-11, it is FCC, 1-13 is CE mode. As I got 13 channels, I assume that it is in CE mode.
But don't be too sad, in urban area where there are a lot of wifi at 2.4G (5.8G is not that populated in Switzerland), it is not that good. Using OTG cable and 5.8G helps, but the range is more limited.
I'm not "sad" (what a "strange" choice of words...) I'm using the FCC version so get 1km+ range which is more than I need. My CE/OTG+5.8 where connection was d lost at 300 meterd one 3 minutes after the FCC/OTG+5. 8 test in a field where there is absolutely no WiFi interference so if you're getting 1km with that setup it can't be with CE power that's just impossible. It's just poor form to set expectations people can't replicate.
