HDZ ain't leaving. It's the only system with a consistent latency and has some sort of feedback as to when the signal might drop. WS will suddenly drop without warning, and there's times where DJI isn't much better. I'm hoping that this is something that can be worked into this system. It does look promising and the fact that it's open source, like HDZ, is nice.
@@dooddrones6521 Well... HDZ isn't quite open source. Try asking them for the code for the goggles' operating system (not just the "app" that runs on that OS) or for the code that runs on the Divimath receiver chips... But it does absolutely wipe the floor with *every* other digital system in latency. And add to that the fact that it doesn't suddenly drop the link like the others do, and that it comes back instantly (rather than taking 5s - or a power cycle), and it's a really excellent addition to our current options. All the others are effectively just variants of wifi video (i.e. H264 or H265 video, passed through existing chips - or custom chips that work very similarly to existing ones in the case of DJI)
Dear Tipo Man, I bought the same camera (Hi3516EV300+IMX335) after viewing this amazing video. Would you please tell me which 2 pads of the 16 unsoldered pad are Data- and Data+ for USB connection to the wifi card? I have searched around to no avail, thanks!
@tipoman9317 Dear tipoman, i am using the same gk7205v300 + imx335 as your camera side, however my NVR (ground control side) couldn't decode the received packet from camera through wfb-ng link. There is RX packet received, however, the openIPC osd screen does not have any video
I'm making a fixed wing drone with cubeblack, I wanted to use the herelink transmitter and herelink receiver control. Before watching your videos I thought about using OFDM just for the video, but can I use wfb-ng? Could you give me some documentation or link to study? Can I package the data using MAVlink?
@@tipoman9does this mean you have two different polarizations on the drone too? Circular polarization received by a horizonal E ground earth plane polarized doesnt seem efficient if the antenna on the VtX isnt also both polarizations
@@ecastillo9804 The Tx antenna is LHCP. There is 3dB penalty when receiving CP with a linear polarized antenna, but at least the orientation does not matter
No, it is not a bug. It is а very useful feature Video bandwidth alone is a useless metric, since it is constant all of the time. I show TOTAL amount of data received by BOTH channels. This is much more important value, since when this value starts to drop, I know that one of the channels starts losing packets. That is how true diversity + Forward Error Correction work - if a packet is missed by one of the channels, it is taken from the other. If it can't be found there, FEC tries to recover it. This value is a good indicator that you are close to the range limit of the link
May be I don't get it ... but is there a system where you can have FPV camera transmission, RC link and flight controller all integrated. Most likely this is cheaper then to have all the items as separate modules.
Tipo Man you continue to be an inspiration! I can't wait to build something like this
that is how the OSD should be done.
I don't understand much in that area yet, but this is definitely cool!
Holy cow what a great antenna my friend congratz
What was the airplane antenna?
Amazing! Not only for the video feed :D
Cool one. Definately a competitor for Walksnail and DJI. HDz has left the chat.

Brilliant, Fantastic men keep up the great work! Following!!

How did you configure your VENC + VDEC ? Or are you using Majestic + VDEC ?
@@douglaskoo2354I do not use VDEC. I use laptop with qOpenHD on the ground.
i see@@tipoman9
That is so Nice! I will love to do this.
awesome!
how did you learn to build such devices?
I'm making a fixed wing drone with cubeblack, I wanted to use the herelink transmitter and herelink receiver control. Before watching your videos I thought about using OFDM just for the video, but can I use wfb-ng? Could you give me some documentation or link to study? Can I package the data using MAVlink?
I use ELRS for control and basic telemetry and OpenIPC for video and advanced telemetry. Read the wiki about the latter.
Why two antennae? Divercity rx?
Do you use an RC for control or just MSP commands?
Why are the two Wi-Fi adapters different (one is a white AR9271)?
The receiver is true diversity, if a packet is missed from one of the channels it is taken from the other, if available.
@@tipoman9 Is this system capable of recalling the lost frame (with a little latency increase) like Dji do? Thx!
@@PistiBala You mean request it from the transmitter? No, it can't do that.

What is the latency ???-???
Holy shjt!
How does the system behave when the signal quality is low?
Here I deliberately flew below the horizon ua-cam.com/video/LyF6GGWprFk/v-deo.html
Subbed. Are you one of the devs?
Is the IMX335 the only one compatible with OPENIPC?
There are many more compatible SoC+ sensors, it is explained in the OpenIPC wiki
In your description is says 8mbps and in the OSD it says 21mbps. Bug in OSD?
No, it is not a bug. It is а very useful feature
Video bandwidth alone is a useless metric, since it is constant all of the time.

@@tipoman9 Ah so it's total data rate of diversity, overhead, plus whatever else is in the link. Cool.
