Manually select frequency band with RC

[Hansd]

I just did 1600m@100m ALtitude (CE, 2,4G, Antenna Mod 2 x APA-M25).
But that was pushing it, got disconnect and had to wait for RTH.
But it was quite fluid & responsive up to 1000m@100m and totally carefree up to 500m (even at 5m Altitude).
THATS fine for me.
Up to 1000m i had similar results with cheap & sleep looking Dual Band Omini Antennae.
So those wil be my daily usage Antenna and i will only pull out the APA if in need.

Problem is: WHen the SPark has a disconnect that stupid DJI Firmware seaches freqs again and falls back to 5.8G. NO WAY of getting a reconnect az 1600m distance on 5.8G !
So it has to come back to 400m or so before i was able to reconnect, GRRR.
As we all agree, DJI has to allow LOCK to 2.4G...

Agree, impressive.
I guess this was with OTG?

 

[Ender]

Yes OTG.

@Ender, if you get a working solution for the sms connection can u send me the .stl please?...first thing I'm going to do is rip the controller apart and fix the CE range issue

 

[Ender]

Yes, of course i will share it with the community. But i'llneed to find the time, i am a losy & slow 3D Designer ;-)

put Smartdevice in flightmode and connect USB to remote. DJI GO will connect to the Spark and it IS and STAYS in 2.4G.

When you say "flightmode" do you mean "airplane mode" as if to say turn off Wi-Fi, bluetooth, and data?

 

[Ender]

YES, real flightmode.
By now there are App modifications for Android "out there" that fantastically enabled WiFi Menu even while connected via USB OTG. So with those versions you just wait until controller is "green" THEN plug in USB, go to WiFi symbol and choose e.g. channel 6. After ackowledginf with "OK" it takes 2 secs and you are on 2,4G PERFECT.

I'm happy to confirm that!

Hi Gyus, new to the forum (and the spark) and already really impressed

First of all thank you, Ender! the 5.8GHz were bothering me on my very first flight

But I got the next problem on hand: before connecting my phone with the remote via OTG, I'm supposed to switch to 2.4GHz. But there is nothing happening in the first place. I can hit 2.4 and then hit APPLY, but it doesn't even tell me, the connection will be lost, or anything. Simply nothing is happening.

And now what?

 

[Peter]

You need to select 2.4ghz and then select a channel and then hit apply..

 

[Ammpexx]

I did, it worked, you're the best Thanks a lot!

Just a quick shout out to @Ender for helping me decide to upgrade my antenna and answering my incessant questions! I've only tried one flight so far but easily got to 2,500 feet on 2.4ghz CE with 2 bars left. This is with 2 cheap 8dbi antenna.

Coould you please publish details on antennas thpe, supplier, way to mod the RC and so on.
Thanks
