Long range UAV link 100mw for 60KM was designed and tested

Thank you for doing that. I will try USB later this evening, in case it is somehow related to Bluetooth. I also I have a complete 2nd system that I bought a few months ago for another project. I may take it out to see if it gives any different response.

If you click on the “stats…” link in the upper right corner of the screen, do you see many lost packets?

this a short vers, then I retry erasing the mission and uploaded from drone.

upload 400+waypoint ,with usb or Bluetooth?If missionplanner or QGC gets the confirmation information of flight control and then sends the next waypoint, the problem will be solved. Because the bandwidth of the radio is much lower than that of Bluetooth and USB.

This system looks very interesting! If I wanted to connect a Sony A6000 instead of the FPV camera is it the serial converter I need or would using Gstreamer with a raspberry be good way to go?

Its a great system but you need to wait on Cao or Ricky to answer your question

@ausphoto there are two systems discussed here the M12L and the T12.
The M12L is the first unit that came out to the public and it used analog video. Basically a standard 5.8ghz transmitter. So you could easily connect your sony to that.

The T12 uses digital video and the camera is a serial output camera. So currently there is no way to connect up a sony to it so Gstream would be the way to go. Unless you know how to use a raspberry to convert analog video to digital serial video. Then you could use the Sony or any other camera for that matter.

Hope that helps.

@rickyg32 Thank you for the info it helps a lot. So I am thinking this is where a hdmi to csi bridge board comes in. https://auvidea.eu/b101-hdmi-to-csi-2-bridge-15-pin-fpc/

  1. Connect camera via hdmi to csi bridge
  2. Connect hdmi to csi bridge to raspberry
  3. H264 video from raspberry to T12 receiver (via a wire splice?) This section I am not so clear on.

The camera is serial…transmit and receiver lines.(tx-rx)
Not sure you can splice in as suggested.
T12 is looking for that serial type connection.

This is the part I am not sure of. I am thinking that the hdmi to CSI 2 bridge with a 15 pin ribbon (slots in where the Raspberry camera normally goes) does the h264 format conversion which is the serial format required? Then I am assuming the signal needs to be connected to the T12 receiver link. In the Skyroid T12 instruction video


at 8.10 it shows the FPV camera being connected to the receiver. If using a raspberry - how would one connect?

What your seeing is a serial camera being connected.
It has 4 wires.
5vdc
TX
RX
Ground.
The only way I can see a rPI being connected is if someone figured out how to convert the video signal to the serial format the receiver is looking for. So far no one has come up with that solution. Skydroid has it on the bench but no eta for the device.

Many thanks Ricky now I understand. Sounds like I need to wait for the video to serial converter!

To do what you want. Yes I am afraid so. This doesn’t diminish the fact that the t12 is a great system. Just isn’t flexible enough just yet

Hello to all members of the little “SkyDroid” forum within a forum. Nice to meet you all. It seems like that you have all gone from the old Chinese manuals and software to almost heaven where each new product surpasses the previous. However I look at it, you are all pioneers and you got some marvelous results.
Now, I have two T12 in my shopping cat @ AliExpress, the 3 body camera which costs $269 with shipping and the second T12 comes with the simple camera but costs $320 including shipping. I remember reading Cao’s saying use the regular but it is $60 more and above all ems shipping create a lot of problems with customs here at Israel.
Any reason to go with the more expensive one?
Also I remember reading there are long and short antennas? What is better? And where do I ask for it? And last question, does any of you have used iphone for the app? Either Tower or QGC?
Sorry for the long intro, however I notice that more valuable information is provided whenever I elaborate.
Best, Gal

@gnitzan the receivers at least in the beginning came with large 2.4ghz antenna like you would find on a taranis transmitter lets say. Now the t12 comes with the smaller antenna which you likely are more familiar with. So you don’t need to worry about asking for a different antenna. The T12 is an AgDrone system so when the unit shows up it will come with two rubber boots to cover the antenna. I doubt you will need them. But thats up to you.
You will need a tablet of phone. I use an older ASUS zenpad with no problem.
You also need to know that the video display is an app that sits on top of Tower or Qgroundcontrol. It’s not embedded in either app like if you had a capture card on your phone or pc.
That takes some getting use to but not a lot.
As for the more expensive…sorry I am not sure what your referring to.
Feel free to ask what ever questions come to mind. This group is great for helping out.

cheers and welcome

Hi @rickyg32, thank you for your answers.
In regards to the question about the more expansive , I mean there’s two listings in AEx, the one with “Three-body” camera which is now $267 and the mini camera which goes for $299+26 for shipping, so I was wandering if the three body is much different? Or it’s the same camera with IR leds?
Thanks,
Gal
