[SOLVED] Horus with opentx integration

In case you do not know something or you are not sure, here is the right place for your question.

Any other thoughts on this? I can see nothing wrong with my setup. Also any thoughts on why when I have the MLVSS hooked up that the spirit integration locks up?

Sorry for delayed response.

There is a possibility, that the telemetry connection is not perfect. Because of this, the loading is very slow.
Did you soldered the wires (adapter for your receiver) to the integration cable? Or have you used supplied pins?
You can also take a photo, maybe the problem is just there.

When you connect additional sensor, demands for the connection are even higher, so this may be reason why it is not working (or the loading is even slower).

Another thing you can try is to disable Scanning for a new telemetry sensors.

In the worst case we can ship you a new cable, but we are checking each directly with the radio to make sure it is working well.

We can verify how it is working with Horus and the same receiver you have in a few days. Then we will be sure that there is no compatibility issue (but this is rather unlikely) - we have the same receiver and Taranis and it is working nicely.

Ok thanks for the reply. I will take a good look at the connections. I already have scanning for new sensors turned off and it makes no difference.

I can find nothing wrong with the connections. Here is how I have it wired up.
This is without the mlvss

It is looking well. Unfortunately I can't see inside the adapter (white/red/black wires)
One last thing, but quite important that I have forgot to mention..
How far is the transmitter from the model when testing?

Unfortunately when transmitter is too close to the receiver, telemetry link is not stable. Then the connection will be very slow or not work at all.
Moving it a few cm further will solve the issue completely.
This might be a worth to try.

Thanks. I also thought about the transmitter being to close, so I went into the next room and tried it. It made no difference. Still real slow.

Good. We will verify the integration with the same equipment in hopefully 2 days.
I will let you know as soon as possible.

Yesterday we have tried to connect Horus with 3 different telemetry sensors and it worked in the same way as without them.
Unfortunately it was with a different receiver, so I believe that today, we can test it with the same one as you are using.

Ok thanks. So I am assuming what you are saying is that you saw no slow readings or lockups? Be interested in seeing what happens when when you use the same receiver.

Thanks to our pilots, today we have performed testing and I can confirm that Horus with S4R-SB is working well.
It is working even with 3 different attached sensors, but I have to admit that it is a slower (but this is unfortunately normal),
More sensors = slower speed. But it should always work stable.

Testing pilot also took a video, so if you wish I can send you for comparison. Connection is quite same as in your case.

Interesting is, that with other receiver S8R the integration is working noticeably faster.

But I can also say, that for yet unknown reason the integration is working even faster with old Taranis radio. This is very likely due to yet not optimized Horus opentx firmware, so we will try to contact developers to check this.

Unfortunately we have not exactly same sensor, but I believe that it should not matter too much. If so, than it must affect also other telemetry sensors, which is not good.
So what we should check is how fast it is working without any sensor for you.
Can you measure how fast the Page 2 of the basic.lua script is loaded in your case?
