Hi!
I followed this guide to turn my raspberry pi 3 b+ into a audio receiver with Balena Sound: https://www.balena.io/blog/turn-your-old-speakers-or-hi-fi-into-bluetooth-receivers-using-only-a-raspberry-pi/
Everything in the setup seems to work fine but I can´t find the device when I´m scanning for bluetooth devices.
Anyone experienced the same problem?
Hey there!
Can you share the version of BalenaOS you 're using? Also can you see any error logs?
Hey Mike!
Thanks for the fast reply!
I´m using balenaOS 2.43.0+rev1. When creating a new device in the Balena Cloud dashboard you´re not able the choose version, or are you?
Here´s a picture from the log:
Hello @crydestaahl
Looking at your logs, it seems like /usr/src/start.sh has issues, could you post its contents here?
Sorry if this is a stupid question but how do I get there? @zvin
I tried to go through the Host OS but commands like ls or dir doesn´t do anything 
What do you mean by “doesn’t do anything”?
Have you made any changes to https://github.com/balena-io-projects/balena-sound after cloning it?
The /usr/src/start.sh script is in the spotify container, you won’t see it from the host OS.
@zvin I mean that it doesn’t give me anything back when I write it and pressing enter. You know, typing “ls” inside a folder from the terminal will give you a list of the folders content.
Anyhow, I have not been making any changes to the code after cloning it.
Is it this file that we’re looking for? :
Could you please enable support access for this device and give us its uuid or dashboaad link?
Hey, could you provide the full UUID please? (You can get this by clicking the “copy” button next to the short uuid on the dashboard)
Also which OS are you using? That \r in the error logs looks to me that perhaps a clone on windows has messed with line endings in the file.
I think you might be on to something here. The copy was made from -or on?- a windows computer.
This is the complete UUID: 7052b800e6a85359a87747f634cbd4d2
OS: balenaOS 2.43.0+rev1
Thanks for the help!
Yeah that’s likely the problem, you need to configure your git client to not check out with CRLF, alternatively you can download the zip archive from the github page and push that.
Well you’re a true legend @CameronDiver ! Look at this 
Had no idea a git client could cause these kinds of problems.
Also thank you @zvin for taking your time!
Hey @crydestaahl, just a quick note that we merged the fix to balena-cli addressing the line ending conversion on Windows: https://github.com/balena-io/balena-cli/issues/1273
Next versions would be working here without the need for workaround. So please upgrade to the latest version of balena-cli in your next time.
Cheers…
Hello
I also have a problem on my device, the Bluetooth is not visible, can you help me please?
UUID: e6d14823b11e48750d67584df1e749d2
Hi @bura68, welcome to the forums.
Your device is offline at the moment, so we cannot access to it. Then I’d encourage you to do some investigation yourself to find the root cause. We have couple of knowledge base articles to help you with that like this blog post:
It’d help to dig the logs to find out the exact issue.
Next, I see couple of issues posted on the project repo when I search for bluetooth:
I’d advise you to take a look there as well to see if you have a similar issue. Perhaps another user posted a solution already.
Cheers…
Hello, My Rasberri Pi3 device is now online,

Merci beaucoup de votre aide
Hi, the log above shows a kernel warning on the wireless cfg80211 driver which may indicate some type of hardware problem. A typical problem with Raspberry Pi devices is running on slow or defective SD cards. Balena recommends to use Sandisk Extreme Pro (https://www.sandisk.co.uk/home/memory-cards/microsd-cards/extremepro-microsd-uhs-ii) as it’s the one that we validate with.
Aside, could you please run the “device diagnostics” from the dashboard as explained in https://www.balena.io/docs/learn/more/masterclasses/device-debugging/#22-device-diagnostics, and send us the report back.
Finally, could you please log into the application container using ssh and run:
bluetoothctl show
Thanks,
Hello,
Thank you for your quick return
here’s the “bluetoothctl show” results :
here’s the report “device diagnostics” :
Unfortunately I don’t see anything in the diagnostics that would explain why this is occurring. It might be worth trying to explicitly make the device discoverable with
bluetoothctl discoverable on
and try again. Let us know how this goes.
