Intriging question, what will you do if 51% of the respondants uses WIFI?
Do what makes you happy i would say....

I used to ahve issues with wifi, having to choose channels all the time, breaking up images..etc.   Admittedly, I didn’t stick with it that long before I decided to go OTG.   With OTG it’s very reliable, but I notice some of the settings don’t seem to stick (eg max altitude, max distance, button functions).

Not sure if the 701 Firmware fixes any of this, but I still prefer OTG at this stage

In my experience you get a much more stable and reliable connection with OTG

I have not noticed any difference between wifi and OTG...  That said,  some people using android find a big improvement.
Some Android phones won't use cellular data if the wifi is connected, IOS doesn't seem to have that problem.   So if you are using android and want to have connection to the internet at the same time to stream or download maps, then OTG might be useful to you.

Never used an OTG cable.  Wifi has always worked great. I guess it never made sense to me to use a cable when the wifi connection was only a distance of 4 or 5 inches.  However, I am in the US.  Might be different if I was in Europe.

Using OTG (with iOS for me) can no longer save your settings and will restrict your height and distance, wifi has come a long way and it is dependable in my opinion.

First of all, the recommended connection way is via WiFi. The connection between the Spark RC and the mobile device via OTG cable has not been fully tested, so if you do want to use an OTG, I would suggest that you use it with caution.

Please fly with wifi instead of OTG cable. Using OTG won't make the range larger and it is not recommended.

But it should be:

Androids (most, afaik) can't mobil data Internet, if in a "no internet" wifi connection
And how is the band change, RC-AC connection loss, from 5.8 to 2.4 possible, if the phone does not support 5.8 wifi connections to RC?
On top, the video feed is less laggy and more stabil with OTG connected

So, why DJI is not "just" testing it fully and start recommending it?
All about sales figures for the Mavic, perhaps?

I agree. No disconects, image transfer is great. No glitches and breaks in video. Video delay is almost real time. With wifi it was around 3 sec in my case.

When it comes to video lag, please ensure that no bluetooth device and interference around. And our engineers are working on improving the performance of image transmission。

Thans for all the good answers. I have decided to stop using the otg cable for a while because i can fly much higher without it.  And now i wanna ask you guys if i should use the 2,4 ghz or 5,8? I know that with 5,8 the distance is abit limited. What are youre thoughts about 2,4 and 5,8?

I have recently tested the OTG cable, and I must say it really makes a difference for me especially when taking the Spark to the limit range, the image does no longer lag or glitch, and some how I get less disconnections when I fly to the limit range wich also has been increased when connected to the 2.4GHZ.

I certainly would not give away my OTG cables any more! To me it is simply obvious that a cable connection from the RC to the monitor (whichever you are using) can only be better and more stable than a WiFi connection. On the other hand, if users are happy with the image transmission quality they are getting via WiFi, all is well too. At the bottom line I believe that the key element is anyway, how good the connection between the Spark an the RC is.

But do you recommend 2,4 or 5,8 ghz? Im pretty new to this whole experiens. So i would love some great pros or cons for the 2,4 and 5,8. Greetings from a pretty fresh drone pilot. Ho btw love everything about the experience.

After  4 emails back and forth I have not gotten any REAL answer from DJI support but to send my Spark in for service. My unit is not broken not failing.

I started using an OTG due to the fact that the lag I was getting made it impossible for me to control the drone and even dangerous put in it close to people or objects (by the time I stop the drone, what I assumed it was 30 - 40 ft away it was already more like 10 ft from the objects). All of this while in LOS, but at a certain distance it is hard to judge the real separation between objects.

My quest for info stared due to the fact that with OTG, the GO 4 app will not save greater max altitude or distance, but will save lower values, I'm hoping this is an app glitch and not a "lock" from DJI.

My real disappointment is that DJI in no means has tried to share real and solid information about this product (maybe others either). Util right now I have not been answered the following questions:
1. Will OTG lock my max altitude / distance values due to a bug in the app?
2. If OTG is not supported by Spark, why does it work better than WiFi?
3. Why/where can't I find official DJI answers that do not seem to be dodging the facts?

Any "unofficial" ideas?

Is DJI aware of the situation where max altitude / distance values cannot be modified?

OTG cable is not fully tested and it may cause new problems. For you second question, can you give more details about the max altitude? What is the version of your app? Any error message when you failed to modify the setting?

"may cause new problems"

Yep, that may.
I am still looking for them.
But it is solving SOME other problems.
It is not "it may solve".

It depends on the signal "noise" you get in each frequencies, 2.4 is more unstable in city areas where 5.8 is more stable but has much shorter range than 2.4...you have to try both and see witch suits you best.

I do think in CE it is 2.4 if in non urban, but 5.8 in urban areas.
I FCC, in LOS, it is in both areas a advantage, to stay in 5.8: less interferences
And even in LOS, but far, far away, till now 5.8 is not a deal breaker.

My very old Anrdoid phone (LG G3) can, in fact, remain connected to cellular data while connected to RC Wifi. It's an option you can set in Settings - if your WiFi doesn't have internet connection, use cellular data.
I have other issues with WiFi though. The Wifi client isn't robust enough, and also it always prefers Wifi connections with internet access. If I happen to be near one which it knows, it would ditch the connection to the RC and connect to that one instead.
That's why I prefer OTG as well, even though it's not officially supported. I find it more robust and trustworthy.

I have to use OTG cable with my DJI goggles , can you explain why i should not use it with my phone/tablet?

I never had a video problem with the goggles but many issues with wifi to my phone and tablet?

If you connect the drone and mobile device via WiFi directly, then the max altitude and distance will be set to 50 and 100 meters and are not able to modify.

Hi, when using OTG cable, the return height is limited to 50m.



The max flight altitude looks no problem, but if you enter a number greater than 50m, close the menu. It will return to 50m the next time you open the menu.


App version is v4.1.17(3015). Mobile device is iphone6.

We understand that OTG is not recommended. But this limit didn't happen in former version app.

But you don't need internet. It's even a risk for distracting you from monitoring the flight.

I believe you misunderstood, I use a remote controller to fly my drone.

I will make a video of what happens, to show you, in hopes of making this a learning experience we can all benefit from.

Hi to all !

In my experience as a videographer and Spark user for a few months I would like to say, use an OTG cable.

I have tried a lot of Android devices some old and some new, 7 or 8 of them and I have never been satisfied with the LAG in the picture even when using an OTG cable.

So I bought old I-pad mini 2 for 150$ and that for me was a GAME CHANGER with an OTG cable connected. The LAG was gone.

My advice to Android users is try to borrow I-pad from a friend and try to fly with an OTG cable.

I do not like APPLE stuff "closed code" etc. but my I-pad mini2 serve the purpose, I am on 5.8GHz allways and I have clear picture up to 170-200 metres,away, wich is enough for me.

Hope it helps.

I finally got time to make the videos. I could not upload them to the site so I used private videos on YouTube.







After this video I managed to fly up to 500 meters height with the app stating a max flight altitude of 50 m. I'm happy that I am not limited (seems the aircraft takes the command but the app does not), but I wish everything worked as advertised.
