The Ground Unit had 7.7 V, the Air Battery 14.3 V.
After charging both, Ground Unit showed 8.3 V and the Air Battery 15.1 V
But still the same issue.
At the beginning of the new video is to see a blue LED and the correct Voltage of both Units.

This time, App, TX and MP not started. Sound comes from the ESC’s when not armed.
Thanks Frank. I’m still trying to figure out the best way to set up the ground station for long range missions. Currently the best solution I’ve found is connecting a Android tablet to the ground unit via Ethernet (USB c to Ethernet adapter). This allows QGC to get video stream and UDP mavlink data. However, two problems
Since only 192.168.144.20 gets UDP broadcast (according to the manual) I have to root the tablet to change the Ethernet IP address. Bit of a hassle
the siyi fpv app crashes after 4 seconds displaying a message in Chinese when trying to run via this Ethernet to USB c adapter.
I want to use Ethernet over WiFi to minimize the interference in the ground unit. Does the video over internal WiFi put extra stress or cause interference with transmition on the ground unit? Is it ok to use that the whole time?
About the app message, please check if the Ethernet function in your tablet is enabled. Better disable LTE at the same time.
It is ok to use internal WiFi the whole time, it is on 2.4 GHz.
Frank, can you clarify what kind of new “HM30 Dual Link Fly More Combo” kit you have for sale.
I see only one difference, this is the “Dual Link & Relay” module, but I did not find any description on this module.
HM30 Dual Link Combo
Hi Yury,
Thanks for your attention.
Sorry that we haven’t updated the information about the new combo to the community. I am working on the manual so that we present to everyone the full image when we are to release it.
The Dual Link combo works similar to MK15 Dual Remote Combo, welcome to refer to that part in MK15 user manual.

Chapter 3.9.
Besides, there is also an MK15 HM30 Dual Link Combo which allows you to use an MK15 ground unit and an HM30 unit with the same air unit.
Best regards,
Frank
At the early beginning, it showed on the Display 15.1 V.
Now even worse. Air Unit triple red blinks, Ground Unit solid red
I tried to bind, but it failed.
Air unit not connected to Flightcontroller, only to the Cam.
Battery 12.2 V direct connected to the Airunit.
Will now wait for the ordered Airunits.
Is there a way to put a smaller camera in place of the default IP camera? Really having trouble fitting it into a plane without adding major drag. Are there any future plans to allow using a regular analog FPV camera?
Unfortunately the analog FPV camera won’t work with the HM30 link and SIYI does not have an FPV camera type model. But welcome to pay an attention and if we got one in the future, we will update about it asap.
I decided to accept the fact that there is no way to tuck the camera in nicely - then mounted it on a servo so I can at least look around with the giant thing 
Hope one day you guys can build a air unit that gets video signal from regular fpv camera and then turns that into a rtsp stream. Would be cool. Because currently on smaller fuselages this camera is a bit large. But on big planes no problem.
4 & 5 will be replied after checking with the team
Did you get a response from them on this Frank? Mainly interested in receiving the UDP broadcast on more than just 192.168.144.20. If you guys are using mavproxy to forward the UDP data, you can use different commands to serve data to more than just 1 ip. Multicasting to every client on the network would be ideal imo 
that way your user will never have to set their ip address manually
Is it possible to ask your team how to access this OSD data that is displayed over the video? I’m sure there is an API I can tap into. Please let me know
For me: I would like when you can realize that the Font size could be increased. In this Picture the Font is large enoughe, but with a 10" Tablet the Font size ist much to small.
Agreed 
I’m an Android developer just let me fix your app it will take me a day and I won’t charge hahaha
???
It’s not my App, it’s our App.
I meant to Siyi, the company
@SIYI
I got the Recording HD Cam.
The recommended Program “PolyPlayer” or the Converter to .MP4 is not on the Download Page
as mentionned on the bag label.

I downloaded these files.
In order not to make something wrong, could you explain what to do with this 3 files?
