We all know that there is a little lag on the video caused by the transmission from the camera drone to the final screen on your phone.
I can clearly notice when Im using OTG or wifi because the differences on the lag is pretty clear. This is one of the reasons a lot of people use OTG(Besides the CE issue that causes not been able to use 2.4GH signal for some devices on europe).
On wifi specially when your flying on sport mode the lag is so big that is pretty difficult to control the drone looking at the screen. Thats why from the beginning I started using OTG.
So based on what DJI people on this forum has mentioned about the risks of using OTG I decided on give it a try to the wifi connection.
Last weekend I did a perfect fly with almost no lag using OTG and reaching 2Km distance. I'm on FCC mode.
Yesterday at home I turned on the Spark and connected using wifi and with the drone on the ground I put myself in front of it and checked moving my arms the lag response. It was pretty good.
Then I connected the OTG, disabled wifi and bluetooth and try again. The answer was the same.
So I told myself. May be I don’t need OTG anymore.
So I went outside to the same location I flew last weekend and takeoff using wifi. The signal was terrible. I mean, pretty bad, to much lag.
Landed the drone and connected OTG. I takeoff again, but the connection was the same. It was equally laggy than before.
So I don’t get it. Why sometimes I have this annoying lag and other times I don’t. I didn’t make any changes since last week, no app update, no firmware update. But there was something interfering with the signal. And I don’t think it was the wifi connection. And I don’t think that this time there was a lot of interferences because I was flying on the same spot that last time when the transmission speed for video signal was perfect.
Any idea what may be?.
