Eachine EV300D Latency Fixed? - 'How to' and my thoughts

- It is becoming clear that there have been several versions of the update firmware that potentially explains the different results testers are getting. Without version numbers on the .bin file its impossible to tell which one you have so download the latest would be my advice.
UPDATE (28FEB): Following this video Eachine have added the link to the latest firmware to their site and have committed to continue to improve and optimise the code - see posts below. I'd use the links on then Eachine pages now to get the latest and greatest and keep an eye on the updates as they'll change. I updated on the evening of the 26th Feb using the latest firmware out at that time as shown in the video but not all testers are seeing identical results. Time will tell if this is fixed for everybody but it's good to see Eachine acknowledge the issue and work on a fix...

Thanks for painless's advice. Eachine's website has been updated
Wonderful! Thank you for listening to the community and making things better! Happy flying!
Great to hear!
You don't seem to give any value in your customers.
I just checked your website and you have a random link to a PDF file which is called "firmware" update.
It's a file called 'E04940A1-0345-E812-B5F0-E59518B9556B.pdf'
Inside the PDF is a small link to a google drive container to a random file called 'MERGE.BIN'
wtf is a "MERGE" file ?
I'm in software business for 20 years now and even as an untrained novice child I did a better job in that.
Where is the CHANGELOG
Where is the VERSION NUMBER
Where is a DOWNLOAD LIST OF ALL PREVIOUS VERSIONS
This sort of customer hating behaviour might work in China but it will backfire horribly with western customers.
We are used to professional conduct, we expect a company to pay attention to details.
Also as far as I heard the latency issue is still there as on day one, just with PAL camera streams it's in average better with random 100ms spikes.
That's not a fix, it's a quick hack.
That's why the firmware is called "MERGE", some random developer just copied it "hey test it, it's a bit better than before"
Hey Eachine,let do something with your trash google . now is 2021 and you aren't have any solution to fix it ?
I LOVE your videos! More than once the information you provide in your videos has helped me overcome issues in the RC hobby.
Thanks Lee, agree with the comments on update management and using the SD card. Nice one !!!
Painless thank u for staying the chorus i ordered my 300d after your first video thanks for everything keep it up
Painless360 - Thanks again for this followup video. This is obviously a hot topic lately. I updated my black set of EV300d (NTSC) per your instructions. I do seem to have a noticeable improvement in the latency compared to the original factory firmware. The image does appear to flicker bit more then it use to, but does not appear to be consistent. Also possible a ever so slight degradation of the overall image quality, but It does to be as noticeable while flying the whoop around the house. Kudos to Eachine to continue to followup fine tune the firmware!
The firmware will continue to be optimized
Continued optimisation is great as long as it also includes version control and release notes etc.
Thank you for the information. Because I'm not the only one who had, besides high latency, white horizontal stripes / dashes in FPV video. Short preview: th-cam.com/video/V62CMzJppsk/w-d-xo.html
Well thank you.
when you totally fix that, and i will be ensure in this, i will buy it again! But now my goggles on way back in china, and i waiting full refund for that. Also when you receive it, fix mask, how i made it, in stock it's not comfortable (for all people which use test it) i seen ground in gap. BG (售后同步)Product quality issues 78101706
@@KosherHobby I have the promise of Eachine's FW optimization - solving / eliminating white flashes in FPV video that bothers me and other Eachine EV300D goggles owners.
@@Personne303 i guess it's impossible to fix this goggles in short time, for fix it, Eachine must fully rewrite all software code, video processing, osd, and new functions. so we a waiting ev400d3d ;D, Only one perfect! battery box is perfect in ev300d. Eachine if you read it, just start to sell battery box and straps from ev300d separately!
Great job, Lee! Thanks a lot! 😊
w00t! thanks for the update to their update!
Okay, cool. I’ve wanted to get these for months now and glad I waited.
Dear Lee, I love your videos. They are so educational.
Recently I bought a pair of EV300D googles. Previously I had Cyclops v2 and I love them. Only issue with them is the form factor being a bit too bulky so I thought EV300D will solve this issue and they did.
Now once I got the Eachine googles I tested them and to my surprise I have the following issues:
- The IPD adjustment does not seem to be spot on. In result I see a bit of a shadow in between. My IPD is 61mm (confirmed by a doctor).
- Wearing the googles for 10 minutes gives me headache and my vision becomes blurred after removing them (never had issues like this with Cyclops).
Note: My sight is normal, never wore glasses in my life.
Have you noticed anything like this while reviewing Eachine EV300D?
Thank you,
George
I had something similar when i started using binocular goggles, took me a while to get used to it.. best of luck
The reason why the SD card won't work for updating is probably because it's only used for the DVR. It's a separate component and a link between the processor and the SD card slot isn't normally required.
Gal Kremer did the update and found that the latency was fixed, but a strange wobble was introduced. The next update fixed the wobble, but the latency went back up...it also looked like the latency was really only fixed in either pal or ntsc (can't remember which). Quite a strange set of updates :D
Until Eachine use version numbers we are all in the dark. I suspect that the update file has been changed more then we've spotted. Let's hope they improve versioning and release notes moving forward..
@@Painless360 my thinking is they just sent him the original firmware, which fixed the wobble but broke the latency fix. You're right, it's hard to know either way without proper access. Hopefully a full fix is released soon.
My update was applied on the evening of the 26th Feb using the latest. Seems good so far..
@@Painless360 Thanks Painless! Mine should arrive next week I'll have the u update file ready on a usb to be uploaded :) did you test in both PAL and NTSC?
Thanks for the Info on these Goggles. Eachine updated there site, but Banggood link isn't working.
great video lee
I’m not only having horrible latency after firmware update but complete blackouts with fully charged batteries and completely red images. Got the goggles brand new today and couldn’t be more disappointed.
Any chance I could try the file you have please? The one on eachine's website doesn't fix it for me. Not sure if the file you used was different to the current eachine fix or not.
Ok thank u for the info I will update mines . Question I'm going to do my upgrade today I just got the cable now the sd card will be the same we use in the goggles? Or do I need a different one and leave the one in the goggle?
Did you do the update? Was it succesfull? I am quite nervers to place on order but I like the features.
Hi,
I know it is an old story but is quite hard to follow.
I was following the story around the EV300D. I wanted to place an order but I heard the latency issue.
Did somebody received it after this video relase date? How is it performing?
Was the latest firmware update succesfull?
I want to place an order on it but I a was quite supprised when I saw the first results.
Hello , lastest firmware is 25/2/2020 and now is 2021, how long ev300D user had to wait for ? Or Eachine just give up and nothing to do ?
There was some talk from others that after a code change, latency was only improved for PAL video transmissions, not NTSC. Since there seem to be several code sets, do you know if that is the case here, or is it now solved for both?
Please see the notes in the video description..
The second update fix all the problem? (latency +wawe in the sceen.. ) must I download update 1 and 2? Thank s😁👍
Do you have extensive flood issues nearby? Are you filming flood areas from above to help neighbors with property insurance issues, crop damage or lost livestock?-Bill
Not here. Lots of rain and the fields are sodden but no flooding...
keep it on topic
Do you believe this has been fixed I'm thinking about getting them I have 200d
Now. What do you think.
I bought ev300d goggles june of this year will the update have been done on my goggles cheers
Are these spectacle friendly?
Please see the first look video, I covered all of the specs in there.. They have some impressive adjustment available for the focus.. Happy flying!
Are all issues fixed in 2022?
No idea, I'd check the forums and the latest firmware you can find... best of luck
Chinese customer support still has a way to go.
Did you check the video quality while flying? It looks horrible to be. It's jumpy and very noisy. Far worse quality than the (unflyable) high latency version. Oh. And while better latency than the original it's still higher for me than my other goggles (double).
See the notes in the description...
@@Painless360 yeah. I've tested with all versions.
OG: 100-120ms unflyable latency. Good quality video
Next version: ~30-40ms on PAL. Good video, but micro freezes and rolling artefacts making unflyable.
Latest version: ~60ms on PAL. Horrible noisy and jumpy video. (I'm 99% sure this is the same version you tested, but will try again when I'm home later in case there is 3rd update I'm unaware of).
How odd, I'm getting much less latency on PAL here.. I wonder if there are HW differences too...
@@kevinbernitz6580 Please let me know if you're getting different results. Thanks.
@@Painless360 I own the EV300D since early Jannuary, and went through 3 firmware versions. I started the hobby a few weeks before getting the EV300D with the EV200D, and now own both. Because of beeing new to it I almost flimed every singe flight I did so far, and the count is now over 600 in total. I own 14 whoops so far (a few meteors with a little soldering jobs done (other vtx), a few other betafpv, Mobula6, Trashcan, Tinyhawk regular and S, ...).
In regard to the EV300D I can say that the quality is not consistent at all. I sometimes record the same flight with different DVRs (EV200D, EV300D, Eachine 5", Spektrum 4,3", EV800D) I own, and in terms of DVR quality the EV300D seems to be inferior then most others. I suspect that the low bitrate is part of the problem. On the Eachine5" or Spektrum or even the EV800D the bitrate is much higher, and quality is often significantly better!
At last, I also suspect Eachine to tweak the hardware from batch to batch, so it would be even harder to get usable comparisons, because we never know what revision someone actually is...
It would be strictly necessary for Eachine to implement a revision system in both hard- an software. I understand if they do not want to publish hardware revisions (this could probably upset some early birds as me), but at least the firmware revisions have to be trackable, and a proper changelog is also absolutely required!
Thank you for your brilliant work & best regards from Vienna,
Markus
It's insane how bad they manage their versions. They simply don't have a version, they just throw firmware binaries out like trash.
As far as I could read the firmware fix only fixes PAL cameras and is still randomly inconsistent in latency.
