Hello. I have a question about radio channl quality.

I always do the compass calibration before every flight and I updated the latest firmware succssfully on both dji go app and aircraft

When I tried to fly drone outside, I always got this warrning " Poor radio channel quality" on the screen but when I checked the bars, it was also full signal.

What should I do?? Please help me

What firmware do you have on your aircraft?

What firmware do you have on your aircraft?

I updated newest version 1.4.001 on aircraft, which was released on sep 7
my controller is 1.3.2
DJI go app 2.2

I updated everything successfully but I dont know why I get this warning message.
I tried to fly my p3p outside, but the result was same.
Please help me to solve this issue. Thank you Tim

my smart phone was "DO NOT DISTURB" mode.. Do I have to use "AIRPLANE MODE" ?

Before I fly drone, I killed operating app and use "Do not disturb" mode and do compass calibration..

Thank you ray

yes use the airplane mode, to see if that makes a difference. do not disturb does not shut down wifi, bluetooth etc that may be  interfering

Wouldnt airplane mode turn the GPS off the phone!!

No, because GPS is a receive only function. It does not transmit.

I am having the exact same issue when I use my iPad mini 2 (wifi-only model) even when I have it in airplane mode, which it always is since I use it only for my P3A. I am flying it out in the middle of a cornfield with no wires or towers within 5 miles of me.
I'm also seeing a stuttering video stream while flying as well.

Any idea on this? Is this a firmware issue that would potentially get resolved in the upcoming update?

In firmware update 1.410, DJI has added an initial check for radio interference and alerts you to check your settings if it senses high interference within the spectrum. The radio settings and signal graph are located in the GO App under HD Video Link Signal Strength .

The RC has two setting -> AUTO & CUSTOM. With AUTO, the RC selects the channel it thinks is best/optimum.  You may also select CUSTOM and select your own channel. Channels with interference have a tall red bar in the graph. Stable channels are green and show no bar at all. In my area in the US, channel 20 has no interference at all, so I select this channel under CUSTOM and get excellent and stable performance.

The 8 channels that are available for our use can also be used by wireless routers and repeaters, so depending on where you live and fly, you can get significant interference. Our RC defaults to automatic channel selection from channels 13 to 20, and can change channels if significant interference is detected during flight.

DJI Lightbridge uses radio channels which are within the ISM bands to transmit video back to the RC. The P3 has antennas in the landing gear that communicate with the RC on 2.400 GHz - 2.483 GHz. DJI initially implemented 32 channels within this band but later discovered that only 8 channels (13 -> 20) were legally available. The other frequencies are in used by ham radio, satellite comm,  or are used by wireless carriers in various countries. Sploodge offered a hack to enable custom selection of the original 32 channels here: http://forum.dji.com/forum.php?m ... 7&fromuid=44480
