Lovely job ! +1

 

[Markhull]

Was looking forward to trying this but my Macbook won't connect to the Phantom3XXXX wifi connection. Anyone else had any luck?

 

[BaDvs3viL]

Im actually going to test out that script now. I wont make it auto start until I know my other devices, such as phone and laptop can connect on channel 13 here in the US.

 

[harry9s]

Is the benefit of channel 13 just due to less interference? That script seems like a lot of bother just to change the channel. Although if you were in a congested area with channel 13 free then I suppose it makes sense.

Thanks for help. Do it in private message next time.

Yes, it should be less interference at channel 1 or 13, I live in urban area which my phantom found more than 20 SSID when I test the script at home, most of them are channel 1 to 11, so I want to find the best channel for every flight

 

[Ojcze Nasz]

I use LinSSID software.
Shows a nice graph.

1. Networks in my home without phantom on

2. With remote on. I have it on ch 13 since is the cleanest.

Signal strenght goes beyond scale. Beside 27dBm I just installed patch antennas I received this morning.
** ERROR is not an error. It's my own home wifi

 

[Wodzu]

Thank for your efforts. I tried to change the mode to FCC. I did check the message that was changed US without GPS signal(indoor) But, it was returned back to GB(CE mode) when my drone received GPS signal and recorded home point.

Confirm. I also changed to FCC (check: 27 dBm via telnet, drone and remote) but after received GPS signal and recorded home point (Poland) it again back to 17dBm (CE)
What we can do?

 

[BaDvs3viL]

Here is my script for Auto scan best channel from 1 to 13 (set unused channel), it will patch RC and drone as same time, then show wifi detail result after patch completed.
I don't touch DJI original /sbin/chansel because it is a binary file and I don't know what it done
so let's the original boot process complete, then execute custom script to avoid bricke the RC

- How to install
1) save script as "selchan.sh" at /sbin and chmod 775
2) enable telnet.d in rcS file at rc and drone
3) Patch force FCC mode if necessary
4) turn on rc and drone
5) telnet 192.168.1.1 and execute selchan.sh
6) check onscreen result, if result ok with no error, add "sleep 30" and "selchan.sh" in RC rcS file at last line to make it auto run when boot (sleep 30 for avoid script run b4 drone connected to RC)
7) user also can execute with argument to set channel number manually, eg : selchan.sh 13

PS: if you want to disbled telnet.d after make it auto execute when RC boot, You can add "iw reg set BO" in rcS at both side and remove "#patch drone side to BO" inside the script

PS2: Wifi channel can be change during in flight ! execute the script by android telnet program, and video downlink stream in DJI GO will be resume after network restart completed !!

Can you tell me why the script inst running for me?

Nevermind, I got past that by telling it to use sh.

Now I am getting this...

if you save the script at /sbin
no need to use ./, just type setchan.sh (your file name selchan.sh)

Yeah that didnt work either. I had to force it with sh. But now I am getting this.

pls double check the file content, how come you can't execute a simple "clear" and line7
or try to save it at /etc/init.d and execute by ./

Managed to attempt this but controller now won't connect to drone - ****. Any ideas?

I edited the rcs file as per the instructions and uploaded the file to remote and drone.

You can still connect to the controller?
