HereLink

Hi.

I have a Herelink sistem bought from UNMANNED TECHNOLOGY in 2020. From 202o i am trying to make it work but no change. The sistem is updated but the video link is not working. We try with different cameras but no luck.

The other day i saw the Uplink rate is from 1 to 4 kb max.
IS here anyone that can help me ( i pay for this) to know what is the problem or can help me to solve it.

I can give acces to my computer, i can do video(not chat :slight_smile: )

Thanks

Hi Petre,
May I confirm few things first?
Did your controller and airunit firmware both been upgrade to latest version?
Did you power airunit with 7-12V power supply?
What LED indication shows on your airunit?
Which method you connect your camera?(I tried sony 5100camera,hawk eye,gpro5 and 9 with micro hdmi cable,they all works fine)
Did your camera screen turn dark after connect to airunit?
Did you try both port?(hdmi 1 and hdmi 2)
Did you try with another hdmi cable?
Can you take a picture of your setup ?(with airunit , controller and camera together,same as you tried before)

Hi

  1. Both controller are on latest firmware.
  2. yes power the air unit with 3 s(12v)
  3. led number 2 on air unit
  4. micro hdmi different cables that we tested first( to not have bad cables) we use also normal cables not thin because the thin cables are different.
  5. NONE of the camera turn dark.
  6. Both hdmi.![IMG_4762|375x500](upload://A5GkLTz9JR4LAqIb2YpnM9EsGhD.jpeg) ![IMG_4763|375x500](upload://4juR8u3HP7hiUbdXVoeqEY7ceY0.jpeg) ![IMG_4765|375x500](upload://9yGwQTL1TBUYPHSBS5fQBArsuMj.jpeg) ![IMG_4766|666x500](upload://n1qDmxcWhbz7Y7ntzEeTgv31r0Q.jpeg)

I notice that ther is no light on led 1 ,which means “Receiving no valid video signal or flight controller signal”.
Can you check the hdmi output signal from your device and make sure they are 720p 30fps or 1080p 30fps or 1080p 60fps ?

8

YES , no led 1 on because is on desk . when i am give him signal Uart the let 1 will be on but no video.
I can confirm that i tried with a signal converter and we tri to give him(airunit) all the kinds of signal like you sugested.

Did you try with labtop before,can you try that?

10

i don t know what you mean by, to try with a laptop?

11

Can you connect airunit to laptop see if it can get video stream from that?
Also,please take a picture with your herelink GCS(QGC>Video stream) ?

12

I don t know how to see on laptop the video stream from airunit. is there any aplication to do that?

Thanks

Sorry, what I mean was connect laptop to airunit with HDMI to micro hdmi cable directly(see on herelink if you have a video stream which from airunit), and use QGC in herelink
