Failed to execute management command 'scanend'
Closed this issue · 10 comments
Hello everyone. After finding out that the lightouses on steam vr for linux are borked i wanted to give this script a try.
But unfortunately it seems like my computer hates bluethoot with a passion and it just refuses to work.
Whenever I launch the scrip for turning on the base stations the following error pops up:

It would be really cool if I managed to get it working
Please send me the output of hciconfig -a
.
If you have exactly one bluetooth device, this is a problem with your hardware and not this repo.
If you have multiple bluetooth devices the wrong one might be used for scanning, I might be able to help you in that case.
Here it is. I have two totally different bluetooth adapaters, so i'll show the hciconfig for both:
This is from a tp-link bluetooth adapter

But looks like they are basically the same, only a slightly different Bd address
Just noticed the scripts runs kind of randomly:
Most of the time it errors at every attempt. Then once in a while looks like it succeeds.
These are the logs of two runs of the same script without any change anywhere:

firestorm7893@firestorm7893-desktop:~/.steamvr_utils/scripts$
Can you please send me the output of hciconfig hci0 features
(with one of your adapters connected)?
Does the success of the script depend on :
- which adapter is connected?
- how long it has been connected for?
- if the previous run was successful?
I only have a single none removable Bluetooth device, so I cant test this myself: how does the output of hciconfig -a
look like when both devices are connected and what happens when hci0 is disconnected (but hci1 remains pluged in), can the be a hci1 without a hci0 (which would probably cause the script to fail)?
In the second log you send the scan also failed. There should be lines like Connecting to c2:ce:42:ef:fd:a0
, but your scan did not find any Base Stations (I am assuming there are Base Stations near you). I will add an error message for that.
I will add an error message for that.
Added in 34dd4f3.
Heres the output of both adsapters:

And the stations looks like they are being detected. (i also tried connecting to the trough the menu but nothing :( )
which adapter is connected?
Looks like pure luck to me, 9/10 it doesn't work. I tried various combinations (different adapters, using sudo, setting the stations up in the settings
how long it has been connected for?
plugging and unplugging them do not seem to matter. It's really weird.
if the previous run was successful?
It will fail for sure, or at least it happened every time
Based on the image I assume you have V1 Base Stations. That might be an additional problem here, I only have V2. And as far as I know no one (except now you) has tested this repo with them.
But the Failed to execute management command 'scanend' (code: 13, error: Invalid Parameters)
is definitely not caused by the version of your Base Stations. Based on my limited knowledge, both of your adapters should be capable of running this repo. But that does not seem to be the case, I don't know why.
You can try this repo (no relation to this one): https://github.com/risa2000/lhctrl
It supposedly works with V1 Lighthouses. If that works for you, you can make a new issue here to include their script in this repo.
Other than that I am unable to help you.
😮 omg i tried all of this time with the wrong version, i feel stupid. Thanks for pointing me in the right direction
I'm having the same issue with V2 lighthouses. It looks like it might be an issue with bluepy (see IanHarvey/bluepy#150).
Following a suggestion in that thread, I was able to get it working by replacing
scanner.scan(2)
with
scanner.scan(2, passive=True)
