Jkson fcc mod question #13

Open brett8883 opened 5 years ago

brett8883 commented 5 years ago

@brett8883 Can I Super-Patch my bird AGAIN without causing a problem?

During the first patch JKSON_FCC_MOD offered:

1 - Auto Frequency (Default) 2 - Force Frequency to 2.3G 3 - Force Frequency to 2.5G 4 - Delete this Mod

Since I did not know exactly what each option did exactly, I followed the video and picked 3. Can someone please briefly explain what each does and why I would want/not want it?

Then POWER:

1 - Default Power 2 - Default > FCC > Boost > Reset. Loop Selector by Remote Controller 3 - Fixed FCC 4 - Fixed FCC & Boost

Again, since I did not know what each option did exactly, I followed the video and picked 4 Now I read that option 4 could cause OVER HEATING via the RF Chips. Can someone please briefly explain what each does and why I would want/not want it?

This will help me and others reading this decide what they want to do.

Thanks!

@mtebbens your question was unrelated to the issue that you originally posted it in. I have moved your question here and deleted your original post.

You would be better off just doing the stand alone version of jkson fcc mod instead of repatching, though no, you wouldn’t mess anything up it just isn’t necessary.

I can only speak to the frequencies and power form my own experience because I am not the creator of jkson_fcc_mod but I have never had an issue with the fixed boost + FCC and never heard of someone who has.

I think choosing “auto” (#1) in the frequency selection will be best in 99.99% of cases. There was a moment I thought about not offering the other options for frequency in Super-Patcher but decided it wasn’t my right to decide what was best for people. It’s possible I may restrict the options in future versions just due to the amount of confusion about them but you can always do the stand alone version here https://github.com/jkson5/jkson_fcc_mod

BorisPlintovic commented 5 years ago

Hi brett, I tested the Jkson mod on Spark. "busybox ping -c 1 -w 1800 192.168.41.2" Spark does not seem to support it "dji_mb_ctrl -S test -R local -g 9 -s 9 -c 27 00024800FFFF0200000000" Spark set up FCC at start/restart, but apk Go4 display "prompt to change region OK / Cancel"

brett8883 commented 5 years ago

@xitanaf jkson fcc mod does not have documented support for Spark but from jkson5’s response to some of the questions asked of him it sounds like there is at least an outside possibility it could work. If you’ve been able to find a way to get it to force fcc mode on Spark that’s a big accomplishment. I don’t have a spark and I already live in FCC in a fcc country so I can’t test it.

Give us an update on how it goes and if you notice better reception.

BorisPlintovic commented 5 years ago

OK. I have 2 mods. Force FCC and Force FCC+TXPOWER Force FCC is standard, any start/restart aircraft, the dron automatic set FCC TXPOWER is as Boost, the distance is a little better, about +20%, but signal stability is great. The image is fixed until the end of the range

Here is extract from file check_1860_state.sh Force FCC:

!/system/bin/sh

/system/bin/check_1860_state.sh& while : do dji_mb_ctrl -S test -R local -g 9 -s 9 -c 27 00024800FFFF0200000000 break done

Force FCC+TXPOWER:

!/system/bin/sh

/system/bin/check_1860_state.sh& while : do dji_mb_ctrl -S test -R local -g 9 -s 9 -c 27 00024800FFFF0200000000 sleep 10 iw phy phy0 set txpower limit 3500 break done

brett8883 commented 5 years ago

Nice! I’m gonna have some people do some tests for me and if it pans out I’ll add it to Super Patcher and credit you for your work!

Great work!

brett8883 commented 5 years ago

@BorisPlintovic do you have any insight on what all tat is actually doing? And how did you find out what to do? I’ll admit while I understand what it does I don’t understand the mechanics of how it works.

Any idea if this would work on other drones?

brett8883 commented 5 years ago

Oh wait😲. I think I might get it. So you put Spark into FCC mode and then pulled the Check_1860.sh to check the settings and then you can call the modified check_1860.sh at start up?

BorisPlintovic commented 5 years ago

Tommorow i send you .bat file for Spark.

brett8883 commented 5 years ago

Tommorow i send you .bat file for Spark.

Thanks But is that how you figured out what settings to put in to force it into fcc? I’m really just curious how that was done. Maybe we can get it working for other aircraft too.

BorisPlintovic commented 5 years ago

For over a year I used the command "iw reg set US" to switch to the FCC A week ago I tried to use the jkson5 command for MavicPro "dji_mb_ctrl -S test -R local -g 9 -s 9 -c 27 00024800FFFF0200000000" and it work just as well. I think the jkson5 FCC command will work equally well on all drones. Here is the .bat file for Spark: https://drive.google.com/open?id=1vkLXswF3P547JGORAlZMrrDQd9fCj1gs

ausdim commented 5 years ago

@BorisPlintovic Try that on my spark but didnt turn to fcc. Btw bird allready patced with latest super-patcher.

Thanks

BorisPlintovic commented 5 years ago

I tested it on FW AC 0900, 1000, 0900 SuperPatcher FW RC 0400 Go4 4.3.20 After installing fcc mod, apk will automatically report (popup window) a different region and asks to restart wifi (OK / Cancel). Click to Cancel and FCC to stay

mosheas commented 5 years ago

Hi BorisPlintovic Did you get a greater distance and stable image quality by the end of the reception area? At what frequency did you work 5.8 or 2.4?

brett8883 commented 5 years ago

I tested it on FW AC 0900, 1000, 0900 SuperPatcher FW RC 0400 Go4 4.3.24 After installing fcc mod, apk will automatically report (popup window) a different region and asks to restart wifi (OK / Cancel). Click to Cancel and FCC to stay

Thanks @BorisPlintovic. I’ve given it to several beta testers to try out so I’ll keep you updated on the feedback. Everybody is excited about the prospect of a Spark FCC mod.

mosheas commented 5 years ago

Thanks so much .. Definitely exciting to hear good news (:

BorisPlintovic commented 5 years ago

Fly in 2.4 I fly out of city and 2.4 have better penetration in terrain In this mod, 2.4 and antenna 4hawks SR is my distance record 6105m https://youtu.be/zeXvTDzU-Ko

ausdim commented 5 years ago

Tried on 0900 but cant go to fcc. I try also to reflash stock 0900 firmware and super patcher > fccmod with the same results again. Btw all seems ok and the .sh file is at vendor/bin folder.

Weird. Also as i see your versions the only diff is that my remote is not 0400 cant remeber exactly cause im at work. Also where you found 4.3.24 go 4 apk?

Many thanks for your work.

mosheas commented 5 years ago

Disappointing me to hear that it didn't work...

ausdim commented 5 years ago

Dont want to disappoint anyone maybe is something at my side only. I wish... Tried both the fccmod bat file and also tried to manually write the commands throw adb shell but same results. Fcc comes only if i use fake gps.

Also mkdir vendor/bin gives an error that folder allready exists maybe a "-p" fix that..

Any way im here if something new popup to test it.

Also is it safe to delete vendor/bin folder? Cause as i see after reflash 0900 firmware the files didnt refreshed here.

Thanks

BorisPlintovic commented 5 years ago

then the problem is in rc firmware 600

ausdim commented 5 years ago

Thats maybe the problem... I try to downgrade and see the results. What the diff with that two rc firm? Otg stuff? Soory but cant search now @work

BorisPlintovic commented 5 years ago

One idea, you can try rewrite "dji_mb_ctrl -S test -R local -g 9 -s 9 -c 27 00024800FFFF0200000000“ to "iw reg set US" in .bat file

ausdim commented 5 years ago

Allready tried "iw reg set US" via adb shell but no go... But i will try again when i go home.

Also when i try "dji_mb_ctrl -S test -R local -g 9 -s 9 -c 27 00024800FFFF0200000000“ via ad shell something is given as answer but cant remember... some letters and numbers..

BorisPlintovic commented 5 years ago

interestingly, I also tried "dji_mb_ctrl -S test -R local -g 9 -s 9 -c 27 00024800FFFF0200000000" manually in ADB and did not get any error

ausdim commented 5 years ago

Isnt "error" but something else.. bont know what.. i will post it back when i am @home

brett8883 commented 5 years ago

@BorisPlintovic with the limited feedback I’ve got back so far things are looking good. The one beta tester who has reported back is very impressed. He says he got over a mile in a highly congested area. I’d like to get some more feedback from a few other people but wanted to give you the update

ausdim commented 5 years ago

Thats great news... What rc firmware user is on? Thanks

ausdim commented 5 years ago

Thats the message i got when i try to manually put the code via adb shell.

root@wm100_dz_ap0001_v5:/vendor/bin # dji_mb_ctrl -S test -R local -g 9 -s 9 -c 27 00024800FFFF0200000000 Send message, from 1e00, to 0900, msg_id: 00090027, attrib: 00000040, len: 11, data: 00 02 48 00 ff ff 02 00 00 00 00 Resp message, len = 1, data: e0 root@wm100_dz_ap0001_v5:/vendor/bin #

Also just downgrade my rc to 0400 and reflash stock 0900 ac firmware and restore factory defaults via assistant2 but the bird dont want to go to fcc.

Thanks

Hold up you are just typing the commands into the shell at vendor/bin?

ausdim commented 5 years ago

That time yes but tried also from root. Spent a lot of time to that situation... dont know maybe the fault is somewere else.. How you have reports that is working and for me isnt works? Make me think... Thanks

mosheas commented 5 years ago

@BorisPlintovicoes Does the spark file.bat, you've moved her should to work well, or do i need to change any parameters?, thanks.

brett8883 commented 5 years ago

I just have the one tester who has reported back so far but he’s usually not easily impressed but he’s over the moon lol. Says he moved to a lower interference area and can’t out fly the signal range before needing to return due to low battery.

brett8883 commented 5 years ago

@BorisPlintovicoes Does the spark file.bat, you've moved her should to work well, or do i need to change any parameters?, thanks.

There’s nothing additional to the bat file that is needed.

mosheas commented 5 years ago

I tested it today ver - RC 400 and AC 900, app ver 4.3.20, I have pached by the File.bat for Spark, so In testing no change to fcc, I was not notified of zone change, basically nothing happened. I restarted several times, and nothing changed

BorisPlintovic commented 5 years ago

channel chart in apk may be wrong Takeoff, landing and after check log file in dji/dji.go.v4/log/cache/areacode, if you see US

mosheas commented 5 years ago

In the testing the distance was 300 meter on open area then I lose connection,It's exactly the same place same distance before I did a fcc patch

ausdim commented 5 years ago

There is no any file with name areacode in: dji/dji.go.v4/log/cache/areacode Exept if you mean destination: dji/dji.go.v4/log/cache/areacode/ That have only encrypted log files...

And you guys having trouble you are using the batch file Boris uploaded above correct? You haven’t modified it in any way? You aren’t just adding his command to some other script correct?

ausdim commented 5 years ago

Yes i use multiple times the bat file untouched. Also restock my ac with 0900 and reflash super pather and again the bat file with no fcc again. The only think havent do is to try fcc mod bat at stock firmware i mean with no any mods on it. (Super-patcher)

Thanks

mosheas commented 5 years ago

Yes, I using only with the batch file Boris uploaded, I didn't used with super patcher or other scripts command in any time.

BorisPlintovic commented 5 years ago

I do not understand where the problem may be. :( I have 2 sparks, one for testing, the other for flying, it works on both.

mosheas commented 5 years ago

Boris... Maybe because they are constantly on fcc so you have no problem, try changing to CE and then reboot and check if you have a message to change zone

BorisPlintovic commented 5 years ago

I tried to change the chmod command and delete the busybox Try new version https://drive.google.com/open?id=1vybqWPsern6zRj30243pJvcDoNY2T4R5

BorisPlintovic commented 5 years ago

Boris ... Možno preto, že sú neustále vo fcc, takže nemáte žiadny problém, skúste prejsť na CE a potom reštartovať počítač a skontrolovať, či máte správu o zmene zóny.

So I did. Use apk to switch to ce, check the log and graph in apk (13ch). He then applied the mod and received a warning from apk that the drone was in the FCC

mosheas commented 5 years ago

I did it with fcc spark_v2.0,no change it's doesn't work. ):

mosheas commented 5 years ago

Boris please see PrtScrn of process of patch ver_2.0, Do you think this is correct?
