Laser Antenna Connection issues

Crazy Moose shared this bug 7 months ago
Reported – Awaiting fix

Hi Keen;

When are you fixing Laser antennas? The issue has been reported over the last 12 Months by a lot of your dedicated customers. A couple of years ago, I was able to use them without issue when I set up a planet wide network using a series of repeaters interconnected by laser antennas around the planet. I would also like to be able to control a drone over a large distance just like it is depicted on your Title screen video.

As they are at the moment, they are totally useless.

Kind Regards

Thank you for the report, moving to bugs.

The laser antenna has an upper limit of 10km now even if it is set higher. 1.189.042

Hmm doesn't that make the laser antenna rather useless? I always wanted to use it for connecting bases. Moon to Earth to Asteroid to alien Planet etc... With 10 km, not really an option

what they've done with the game is a disaster

At Michael Schietzsch : Check the wiki and do some tests with distance and power in mind. A while back I had a discussion with someone that wanted laser antenna from earth-like to mars-like and that needed 4000+ solar panels to operate. Earth-like to moon would need be about 17 solar panels.

I know the power draw is quite big, but i tested it with just 15 km and quite a lot of reactors and also in creative mode.

I tested the same thing and neither of my stations had any indication of low power consumption while testing. I set them to 200km limit, about 130km distance away. My station had a large reactor and about 20 batteries full, and while the Laser Antennas would connect, nothing would be visible in the Remote Access panel and in the Laser Antenna blocks, the Known Receivers list remained empty for both of them. So they would report as connected, but not do anything else.

My example is rather... exceptional? I suppose.


The two laser antenna are over 6500km apart and drawing on 1.09 gigawatts each. Both grids are owned by me, both grids are also in safe zones maintained on nearby (yet separate) grids. Each has turned to face their respective counterpart and is drawing on an, honestly, ridonkulous amount of power, but I've seen modded drones with a better success rate against asteroids than these two antennae are having at connecting.

I have the same problem, almost exactly. I am trying to connect a space base on an asteroid to a second base on the earthlike planet. The distance between them is 59.35km. I have the range of both antenna set to 100km and both have the correct receiving laser antenna locked in. However, they are stuck on status "Searching for a laser at GPS coordinates". Both of them - I have teleported between both sites and tried everything I can think of.

Both are reporting they are owned by me, both bases have a masive oversupply of power, both antennas are visibly pointing in the correct direction and I have flown the route between them to verify there is no voxel blocking the signal (rogue asteroid etc). There is not. The only complication I can think of is that the space base has two laser antenna on it and the ground base has three - though only one of each is trying to connect to anything.

I have the same issue. One on a planet, one on an asteroid 38KM away.

- Antennas are ~38.9Km away from each other

- Both have range to >=38km (tried infinate too)

- Both have much more than enough power

- Both have each other's co-ords copied to the other

- Both have line of sight (Quadruple checked there's no debris or asteroids in the way)

- Both grids I have ownership of.

- Single player mode.

Still a problem. I cannot connect my ground base to my satellite in orbit, less than 50 km apart.

photo

I'm on a mars planet with a station on the ground and a relay sat in orbit above. so that i can have comms with any rovers and not have to rely on standard antenna's. the LA are trying to establish connection but are unable to.

This is 100% bugged. The laser antennas used to work fine. Was trying to set up a recon drone to watch something important with a camera. Stuck on searching for laser at GPS coordinates. Was testing before implementing in c survival. Won't connect at 500m.

The antenna is configured correctly. I've been playing since 2014 and have over 4,000 hours in game so not a noob issue.

My laser antenna won't even connect to over 50 meters. (creative world, build lots of batteries, just to test the antenna).. as soon as I reach 50m (500watts) it disconnects. But it keeps reporting the wattage that is corresponding to the distance, also the antenna turns the right way. but no connection.

photo

Oh, I just tried in a survival game and there it seems to work. Maybe it's creative related?

No survival. When I reported 20d ago

Trying to use it to connect a battle station to a base. 2.7km distance, does not work. The base is in a safe zone, but the battle station is not.

Rotating the antenna works. Then it is stuck forever in the "Trying to establish connection to Laser Antenna ..." stage.

Line of sight is not blocked, but the other receiver is in a safe zone.

When I try it from about 30m distance with another laser antenna (which is not in a safe zone), then it works.

Apparently the safe zone is a problem, blocking/distorting the laser.

The laser antenna is seriously bugged. We tried again to use one last week in a survival game. Connecting our orbital station with the ground base. Both lasers say they are 'connected'. But no connected grids can be seen or controlled neither in terminal nor in communications menu. Both bases had a remote control block on them (not that this is required imho).. I hope Keen will fix the buggy laser antenna once and for all. So we can actually start using it in our. games.

Bas, have you played a locally hosted survival game or someone else's Troch based server? They often use a server side plugin named "Concealment" which tends to turn off remote grids if there is no player nearby. Just asking for completeness, so we have all the information here.

It was a locally hosted game, hosted by me. Both me and a friend tried to configure the laser antenna's. All we got was 'connected to ..' (name of other grid). But no way of actually interacting with the other grid.

this is still a issue today

@bodyboarder2528 Great that you found that other ticket with the repro.


It looks like there is light at the end of the tunnel now. It may be fixed in one of the next updates, if all goes well.


I'm keen on using Laser antennas for the first time! (Apparently they have been broken since I've been playing SE or I got unlucky with them.)

And this is why I hate Keen. I only submitted this two freaking years ago. And it only broke a major portion of my Guideline Planetary Defense System, that being the spy satellite uplink used to detect and lock on to approaching ships (still usable, but now it had to have its own broadcasting on and give away its position). It worked fine for years until they broke it in an update. When you break something existing, standard product support practice is to make fixing what you broke #1 priority. Instead, their priority was paid DLCs.

photo

Yeah, they suffer from "priority inversion", indeed.

Remember: There are always a good reason and the real reason.

is the Guideline Planetary Defense System a script?

photo

No, it's a mobile planet-launched capital ship killer using Easy LIDAR Homing Script. Enemy ship shows up in orbit, and you detect it using the spy satellite, lock on by grabbing its coordinates with the satellite (with Raycast Target Painter), and then obliterate it before it can detect your base.

Hello, Crazy Moose,

thanks for letting us know. However, we´re not able to reproduce issue with laser antennas. All and every time it is working on our side.

Can you be please more specific about what exactly is broken? What you try to achieve with the antennas and what are your steps that you perform beforehand?

Are you trying to do it on single player game, on Lobby MP, or on dedicated server?

Can you please provide save file of the set-up world where it is already broken? That would be great help and good starting point for us to be able to investigate the issue.

You can access your save files by typing %appdata% into your Windows search bar and you will be redirected to the hidden Roaming folder. After that just follow: \Roaming\SpaceEngineers\Saves. There should be a folder with your SteamID and your saves. (\Roaming\SpaceEngineersDedicated\Saves - for DS saves).

Please zip the file and attach it here. If you are having difficulty attaching files you can optionally use Google Drive. When sharing a google drive link please make sure it is set to be downloadable by anyone with the link.

If you can also make and share the video of this bug happening, that would definitely help as well.

Thanks for the info and files in advance.

Kind Regards

I have the exact same issue and a quick google search shows countless other reports of the same problem many of which have been posted to this platform. The lazer antennas straight up dont work they do not do anything at all when simply trying to connect two of them together as they are intended to do. They just say searching for connection and never actually connect no matter the distance and even with clear line of sight.

Just a quick question, what kind of hardware are you guys using to check the game on?

There are countless trivial issues with the game that many players experience yet you mostly cant reproduce the issue so i am asking what kinda supercomputers are you guys playing/working on?

I have a Ryzen 3800x slightly underclocked and a GTX 1070 overclocked with 32GB 3200 RAM.

Thanks Ondrej;

I am trying to use them on a dedicated server not hosted by me. So I am sot able to send you a game file. I have raised the issue with the server owner. He saw no reason why they should not work on his server.

I was able to get a connection in a single player environment. Why shouldn't Laser antennas work on a dedicated server?

Cheers

I am also having this issue. Would a save file be helpful? It's a 9MB zip, so too big for posting. Email it to you?

Hello, Brian.

Yes! Definitely that would be a great help! Also some steps what you are trying to do on that world with the antennas as already asked for it before (or video - that would be the best). It must be something "special" or just one little thing that you do, that we don´t when trying this. And believe me we did try it tens of times - still working for me and my colleague as well.

When the file if too big to attach it here, please use google drive for sharing. Make sure that the settings are set in a way so everyone (us) can view, use and download the files.

Thanks in advance.

Hope we can finally reproduce it as well.

Kind Regards

Oh, and don't fall in the hole... ;)

Hi, Brian,

thanks for both - video and save! It was really big help. Issue was finally successfully reproduced and thus put into our internal system.

Let´s hope that´s all with laser antennas at least for some time :)

Kind Regards

P.S.: Yeah, I did fall to the hole couple of times :D

So, I am wondering if maybe a mod is breaking it? Will have to test mod free. I have my non-creative world, have link, remote blocks and can see the grid, but can't communicate... Odd...


See attached.

Nope, same issue with no modes (the no-connect issue).

Looks like this will never be fixed. If this is not fixed in the next update, then we should consider a client plugin (+server plugin if needed) to fix this. Really, this should not take years...

Start changing your reviews to negative on Steam. They only start fixing things when their reviews drop a tier.

I can confirm this is still an issue and that the connection is lost around 23,331m from point to point even if the range is set to a value greater than that.

This is still an issue as of build 198.033, Laser Antennas connect, but the connection is constantly interrupted and then lost completely at about 40km distance.

Are you sure you have enough power on both endpoints?

I have a huge sun-tracking solar array that previously worked for a 50+ km connection no problem. Once this bug was introduced, it just stopped connecting. This is not a tiny array, either.

Was using fusion power for my setup, Many GWs available.

Could you please attach a test world where this problem happens?


(ZIP the world, exclude the sbsB5 file and the Backup folder)


If you have a lot of grids in the world, then please also write down some instructions where to look to find the laser antenna pair.
