[Bug 1565940] Re: bluetoothctl systematically hangs when there is no bluetooth hardware
OK, I can finally reproduce the problem, but I had to manually kill my bluetoothd before I could make it fail. I guess a Kubuntu session is similar to that environment. Confirmed, but low priority. For a better idea that avoids bluetoothctl see comment #12. Finally, please log the bug with the upstream BlueZ developers: https://bugzilla.kernel.org/enter_bug.cgi?product=Drivers=Bluetooth and then let us know the ID of the newly-created bug. ** Changed in: bluez (Ubuntu) Status: Fix Released => Confirmed ** Changed in: bluez (Ubuntu) Importance: Undecided => Low ** Changed in: bluez (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1565940 Title: bluetoothctl systematically hangs when there is no bluetooth hardware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1565940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I suggest a better way to detect Bluetooth hardware is to check with the kernel directly: if /sys/class/bluetooth/ exists and is non-empty then ...

I can reproduce the bug in 16.04 but it seems to be fixed in 18.04: $ echo '' | bluetoothctl No agent is registered $ $ bluetoothctl < /dev/null [bluetooth]# quitt to bluetoothd... No agent is registered $ I'm going to declare this fix released and nominate 17.10 for a fix (whatever the fix would be). ** Changed in: bluez (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1565940 Title: bluetoothctl systematically hangs when there is no bluetooth hardware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1565940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for reporting this bug to Ubuntu. Ubuntu 17.04 (zesty) reached end-of-life on January 13, 2018.

But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed. ** Changed in: bluez (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1565940 Title: bluetoothctl systematically hangs when there is no bluetooth hardware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1565940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1565940] Re: bluetoothctl systematically hangs when there is no bluetooth hardware
Now I understand your use-case. You probably could achieve similar with $ systemctl status bluetooth.service. Also hcitool can tell if the adapter is up and running but keep in mind that hcitool is depreciated and no longer maintained by the upstream. As for the man entry suggestion yes that could be something to consider given that the default man page is quite vague nevertheless this, as whole bluez, comes straight from the upstream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1565940 Title: bluetoothctl systematically hangs when there is no bluetooth hardware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1565940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1565940] Re: bluetoothctl systematically hangs when there is no bluetooth hardware
My particular use case is to detect, inside a shell script, if there is any bluetooth hardware at all. Since 'bluetoothctl' systematically hangs when there is NO bluetooth hardware, I can NOT use the 'bluetoothctl' command to achieve this use case. But I have found a good alternate method : if rfkill list | grep -q -i Bluetooth; then ...; fi So, the issue is NOT blocking for me. But I suggest that 'man bluetoothctl' should indicate that 'bluetoothctl' waits (possibly indefinitely) for answers from the 'bluetoothd' daemon, and therefore is NOT adequate for scripting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1565940 Title: bluetoothctl systematically hangs when there is no bluetooth hardware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1565940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1565940] Re: bluetoothctl systematically hangs when there is no bluetooth hardware
I'm afraid that this is how the bluetoothctl is designed. This tool is a
command-line interface to the bluetoothd and requires it up and running.
It will not quit however when it is not running for a situations where
the daemon might come back online.
Ubuntu does not do anything special here, the bluetoothctl tool is
packaged as is from the upstream.
For Ubuntu this normally should not be a problem because a user is
expected to use {unity,gnome}-system-settings anyway to interact with BT
subsystem. Is there a particular use-case that is failing on this
behavior?
