I think is a bit weird to lose signal with my RC and spark 43m height and distance 97.4m and 16 satellites !!!!!!!! And i see that from a distance and far (i think 50m distance) always have bad signal (video) and sometimes disconnects from RC also..! I am afraid to fly farther...! Whats the point to fly only on desert ??? that i have non obstacle ? not even a tree ????

Any ideas ?

This morning I was flying above an old parked train, flew down the distance of 6 cars before losing connection. 185 feet. To date the return to home has not worked once.

Return to home works fine for me...! but when DJI says 2km ....! 97.4m to lose signal...!! ITS VERY FAR FROM 2KM

Yes me too very disappointed with Spark signals. I was flying my Sparky with RC at Patong beach (Phuket) last Saturday and kept losing signals even at just 50m away. I've finished all my 3 batteries and what I've got was bunch of useless static footage. Drone can do recording but couldn't move due to weak signals.  Kind of waste my effort and money travel to Phuket with the hope that I could captured some nice beach video. To make it worse, not far from me, there was a guy flying his China brand drone (Sixma) happily without any signal issue.

I can understand if it happens at the urban area with tall buildings but come on I was at the beach.  I could easily lost my signal even when flying 50m away at the 20m altitude.
Seriously this drone is really unpredictable and so inconsistence. It could spoil your vacation mood too. Maybe It's time for me to get rid this little drone and move to Mavic air or some other brand?

I think the issue here is your device.
Try version 4.1.15 for spark

This means your RC is still in CE mode and not in FCC mode.

I had the same..  in a Park barely 40m away it just went into ATTI mode when i had plenty of Satelites..   I fear that the Spark loses it's  settings and goes haywire.      Here's what happened to me..  Was streaming it live when it lost control and I couldn't turn it back home..  Thankfully GPS came back and I was able to RTH...  Scary when it happens.  Can't say I completely trust the drone now and have barely flown it further than 200m away from me since ..

I dont think that is the version of software etc . Is the hardware of our SPARK . They produce them quick , they sell it to us very early and we became like beta testers to them....! Then they produce MAVIC AIR and all good.....! I am very disappointed with DJI !

Very many, we have often described the new version as DJI Go app. the range is broken. Use 4.1.15. so there's no problem with 300m either.

Hi Marty,

You can tell it from the number of WiFi channels. If it shows 13 channels, its CE mode, 11 channels is FCC mode.

On a beach, there are people. Lots of them, and they carry their mobiles with them, creating lots of interference. And, you said, there was another guy flying his Chinesium drone...it could very well be that his controlling disturbed the channels you used to fly Sparky.

It doesn't make a difference. If I switch into FCC I have 11 channels, but the short distance stays the same, and I'm talking about flying on an open field with no interference in the countryside.

Even in CE mode it should fly further, right?

Hi Marty,

Yeah sure it is possible to fly Sparky 300m on CE mode at an open field. It could be some defect in your R/C (are you using the R/C?) with the antenna connections or so...difficult to tell.

Is there some sort of emergency procedure to follow when gps is lost? I don't want to hold both sticks down to stop the motors and let the spark fall.
If I do nothing, will the spark hover till signal is regained? Can I use the pause button?
Apart from watching in horror to see where it lands what can I do?

You can still fly it manually like thousands of hobbyists before GPS was introduced to the drones.

I see a lot of people flying around houses and other objects that might mess with their signals.
And at the beach with people using their cell phones.
Imo go to a open field and see how far yo can get out . One guy on YouTube went for a long distance.

Hi,

Well, there's not much you can do when you lose GPS in mid flight. RTH and pause button can only work with GPS. Doing the CSC in the air does NOT turn the motors off.
Only way: keep your bird always in VLOS, and pilot it back in ATTI mode, or descend and land it just where you are.

Wolferl

Thank you for the information, guess I must bone up on my atti skills. Bit of a bummer though as one of my concerns before purchase was loss, but I was assured it would not happen - but it did. Retrieval was something of an adventure with me climbing barbed wire fencing and wading through waist high foliage calling "here sparky, nice sparky, come out wherever you are...."

It’s not buggy, it’s that every new release of the app, requieres more and more powerful device to function properly.
For example the latest app version requieres at least 4gb of ram ( better 6gb of ram) on an Android device to work properly.
You just need to downgrade to 4.1.15 or 4.2.12 and everything will be back to normal.

It has nothing to do with memory consumption on the phone. I get disconnects between my Spark and the RC controller with the latest firmware, that has never happened before. But yes, DJI GO4 is getting worst with every new release. I should probably just downgrade and stick to that. Another option would be that DJI does his homework and fix that app.

Exactly, you get disconnects because the device does not have enough ram to process the flight.
It’s very simple actually.
There’s nothing for DJI to fix. I repeat if you have a very good device then the latest app version works no problem.
If not then just stick to 4.1.15 forever and everything will be fine.
Just make sure to never update the app again on that device.
Each new version of the app requieres more and more powerful device,
There’s nothing to be done Unfortunatelly.
As more features and stuff is added to the app it’s inevatable that the device requirements get higher and higher.
The only solution I see is if DJI made separate apps for different drones,
But that’s not going to happen.

I give you a clear example. On my Samsung galaxy s6 on version 4.3.1 (the latest) I could only reach 50/100 meters tops before completely losing the signal, and I had weak signal warnings on the whole time the whole flight.
After downgrading to 4.1.15 I did 2300 meters on the same device!!!

I second that

Go back to the official 4.1.15 or the MOD 2.0 app (which AFAIK is based on the 4.1.15) and enjoy your Sparky. Updating the app is not worth the trouble.

Also if you are flying in Europe then take into account that by default the drone will be in CE mode, which is topped at 500 meters on both the 2.4ghz and 5.8ghz range.
If you want to go past 500 meters with spark,then you need to change to FCC mode.

Again, there is no proof that this has anything to do with memory consumption. Yes, downgrading might fix the problem, not because of less memory needed but because of bugs not present in the previous version. Also I doubt splitting the app per DJI model would have a huge impact on memory consumption.

But yes, I second that every DJI GO4 update is a PITA, not because of increasing memory consumption but because new bugs introduced in the app. I would prefer that DJI fix that app and everyone upgrades to the latest version than sticking to some old releases.

It's not a range problem because the disconnects happen sometimes at like 30 meters and right after that on the same battery I go to 1 km (but don't tell anyone) without any issue.

Sorry for the delay in my story. Here, being an urban region we suffer great signal interference, due to the large number of routers and wifi repeaters of 2.4Ghz and 5.8Ghz. I could not fly more than 250m and the maximum I get here today is 700m thanks to channel changes in the DJI Go 4 application, for me, that distance is already beyond the necessary.
I use the Android application "Wifi Analyzer" and I see which channel has less interference and I change it manually and after restarting the connection I return the channel search in the "automatic" mode, because in the middle of the flight, that selected channel may be being used in some device (wifi, repeater, antenna, etc) with signal stronger than the communication between our remote and the aircraft.

DUDE IF YOU HAVE A VERY GOOD PHONE THEN THE LATEST APP RUNS WITH 0 ISSUES!!!
LIKE ON MY IPAD AIR2, PERFECT!!!
You abviously are not very tech savvy and don’t know how things work for sure, so I’m not gonna argue with you.
Whatever you say. If you don’t listen, there’s nothing I can do.
Just downgrade to 4.1.15 if you don’t wanna have any issues and change to FCC, that’s my advice.
