Eken H7s
Marietta Bleasdale
Eken has recently upgraded its firmware to version 2.4.1 or higher. We believe this update significantly enhances the security of data transmission. For more information, please contact us at suppo...@eken.com.
We have built for our company 4 identical drones for special spraying tasks, all using Herelink. Everything works like a charm, except for the Herelink (latest firmware, QGC, Arducopter 4.0.7). Here are the issues:
2 units out of 4 can not see some of the wifi networks we can use with the other 2 units. We tried with 5ghz, 2.4, all the possible settings, but still half of the units can not see around half of the wifi networks we tried. It is not a huge issue since it can work, but it is a bit frustrating that on the field we can not use hotspots for loading the map. Is there any solution for this? I read all the topics I could find, but nothing.
Video stream. We use an EKEN H9R which is on the compatible camera list with a quality 1m long micro to micro hdmi cable. The problem is that sometimes we have video ont the herleink, sometimes we dont. It is totally random, there is not pattern at all. We tried powering the camera before, after and during powering the Herelink, we tried multiple different hdmi cables, updating the air unit, everything. Sometimes we have image right away, than its gone mid flight. Sometimes we can only see the waiting for video text, and than a few minutes later we suddenly have image. Basically I could list all the possible versions of having and not having video, like I said, it is totally random. It does not matter if we are inside, outside, mid flight, before flight, after flight. Sometimes it works, sometimes not. No pattern at all. Thats the case with all 4 drones we have. What could this be? How we can make sure to have reliable video?
Also, whenever we change battery, the onboard voltage and other telemetry items stop sending the real time data, and they are frozen to the last number it showed right before disconnecting the old battery. If we restart the Herleink transmitter, than its okay again, but only until the first drone on/off.
It seems rather strange, we have been playing with this for weeks no, we did hundreds of test in the workshop and we can not get the same result 3 times in a row. Right now if it works after turning everything on, than it wont work after the first simulated battery swap. Or if it is working 2 times, than it wont work on the 3rd. Or if it works indeed, than we dont have telemetry data. Unfortunatelly right now It not usable, since we really need the telemetry and the video.

No, we did not misconfigured, this is like the 50th Herleink we used, I know Herelinks are 5gHz, I know the documentation by the letter. And all the 4 units were configured the same. Also some of our partners are having similar issues with the Wifi on new Herelink units, so it is definitelly not a configuration error.
And yes, we configured everythig according to the documentation, we have plenty of experience with Herleink. The only variable that is new compared to the other 50 drones we have built, is the EKEN H9R camera, and that these 4 Herlelink units are brand new, compared to the older fimrware versions we use on other drones.
Altough we have some progress: whenever we use the EKEN with no SD card, and give an 8 second delay to the camera power, it works. If we put an SD card in and power the camera together with the drone wit a BEC, it works totally randomly. Strange.
About the wifi, we tried what you wrote, not working for us. The newer Herelinks we bought in the last couple of month, can only see wifi networks randomly. We tried basically all the wifi settings possible, and can not get the hang of it. Also, any other wifi capable device (smartphone, notebook, tablet, gopro) works on the same 5ghz wifi networks that the Herelink can not see. As a weird addition, we have two wifi in our office, both are seen by the Herelink, but only one can be used to download the updates when turned on the first time. On the other, it always has an error somewhere between 15-50%.
About the video. First of all we dont need recording, we just need the camera for FPV. We choosed the EKEN since it can be turned on by suppying power, and it was on the list, so it is a very conviniant solution for us. Theoretically we just have to plug the main battery, and the video should work. But it only works like 30% of the time, totally randomly.
The output resolution is 1080p 30fps, but we tried all other possible settings, none works stable.
on the weekend we had some other strange events, so to sum up here are the few certainties we could found, with latest everything.
We are open to any solution, since we have spent like 20 hours trying to understand and solve this issue, and it seems to us that the weak point is the Herelink, since any part of the config works alone, except when the Herleink is in the picture. Right now we are working measuring if the EKEN has a reliable 5V and GND on the hdmi out, and if we add a stable power could maybe help.
UPDATE: the stable 5V does not help, unfortunatelly.
just a short update: we tried everything and the bottom line is this: all the parts including the video system (camera, power source, hdmi cable, power cable for camera) is working perfectly alone, or in another sytem, but when we use the Herelink, the stream is totally unreliable and the issue is so random it makes no sense.
If anyone out there is open help, we are willing to pay for the services since we spent 40 hours trying to solve it, but since we can and will not mess with the Herelink, and we checked all other components 100%, we are out of options.
A quick update, we still have these issues and there is no more options we can try (check previous posts), and since there is no traditional tech support (which we totally understand), we would be happy to donate to the developers, to solve these issues we are experiencing, since right now all the advantages of this system is useless wothout these basic functions below:
Hi there,
I have two new herelink systems (updated to latest versions) now and I am also experiencing the same problems when connecting any camera to the Herelink HDMI. 50% it works, 50% it definitely does not, even causing my action cameras to freeze sometimes (Eken, Thieye, other Asus hdmi device too). Regardless which cable I use, which power source is herelink on, when do i connect or turn the camera on. Last Year these cameras were just working fine, I suspect only firmware was upgraded on the newer air units, maybe if I could try downgrading the firmware?
We have experienced similar issues like @Kroly_Bence_Ludvigh. Is there any solution to this? It is very uncomfortable to restart QGC on herelink controller every time, when our telemetry isnt working properly after battery change, or the camera didnt start.
We also still have the same issue. @Michael_Oborne, sorry for bothering, but we still can not use the video function, and telemetry also freezes after every battery change. We tried everything, as you can you in previous post, but the issues still present, which makes nearly impossible to use the system.
1.5 The Mini Cup for B/G8 and B/G9 will be played in a group stage with 3-5 teams. From that stage the team advances to a second group stage with 3-5 teams. All teams will end the tournament by playing a final. All players will receive a medal after their last game. All teams are guaranteed 6 matches, but most of the teams will play 7 matches.
1.8 Draw in the semi-finals and the final position match in the Youth Cup are determined by games for the first goal after drawing of lots. Ties in the finals will be determined by extension 1 x 5 minutes after the drawing of lots. If the match still is tied it will be determined by games for the first goal after drawing of lots.
1.10 Draw in the playoffs and finals for the Eken Senior Cup will be decided by extension 1 x 5 min after the drawing of lots. If the match still is tied it will be determined by games for the first goal after drawing of lots.
1.11 The template used to create the groups in the tournament for The Youth Cup, excluding B/G8 and B/G9, with 16 teams will be as follows. With a different number of teams the second round will be adapted to as tight games as possible:

4.1 Before your first game begins you need to enter your team line-up in our administration system, CupManager. If you have any questions on your team line-up please contact the information tent located at Gubbngsfltet. The team line-up should be entered in the system on Thursday before the tournament starts.
5.1 After the game, each team leader needs to sign the game protocol, the yellow card. If there is a different score between the referees and the score board, it is the score by the referees that is the final result.
6.1 A team may use a maximum of 16 players per game. It is allowed to have more than 16 players within the team line-up. You may use the same player from a club in various teams in the tournament but not in the same age category.
7.1 The home team has to bring a correct size and authorized ball to the game. At a game we allow 3 handballs to be used. All handballs need to be approved by the referee. The 2 handballs that are not used should be placed on the ground near the post of the goal, one at each goal.
9.1 For U16 and younger it is prohibited to marking a single or double players by following then outside of the 9-meter line even though they are not having the ball. If the defense is having the same amount of players outside of the 9-meter line as the offensive team it is not considered as marking.
