Does it work on the older gnome desktop, like 3.38. I faced the same error.

I think it's not compatible with some devices
mine is Anker Sound buds lite

same here

Hi, try connecting to a different port. For example bluetooth_battery.py E8:AB:FA:27:9F:49.1
Try manually changing the numbers from 1 to 30 after period (.)

@Kronodile That didn't help for me, but bluetoothctl disconnect E8:AB:FA:27:9F:49 followed by bluetooth_battery.py E8:AB:FA:27:9F:49 both got the battery level and reconnected it. And then it worked, and battery queries also worked.

same here, but the battery queries did not work afterwards

This is what worked for me

This worked for me too

I am observing the same problem after upgrading to Ubuntu 21.10. To be clear, the Gnome extension that uses this script — and, therefore, presumably, the script itself — used to work just fine with Ubuntu 21.04 up until I upgraded to Ubuntu 21.10.

Now, if I connect my Bluetooth headphones and run the script, it gives the following error:

[REDACTED] is offline [Errno 16] Device or resource busy

If I try manually specifying ports from 1 to 30, it gives the same error with port 4, and with any other port is gives the following error:

[REDACTED] is offline [Errno 111] Connection refused

If I disconnect the headphones and run the script, then it suddenly works! But, unlike reported by others above, this does not fix the issue for me. If I run the script while the headphones are disconnected, it successfully returns a charge level, and the headphones say, “Bluetooth disconnected,” and remain disconnected. It seems that the script briefly connects to the headphones, requests the charge level, and then disconnects. If I then reconnect the headphones, the script still gives the same error while the headphones are connected.

Interestingly, this problem appears to be somewhat intermittent: while testing again in order to write this comment, for a brief moment the script actually managed to work correctly and report the battery charge level while the headphones were connected! I wasn’t able to reproduce this, though; the scenario I described above is still the only thing that happens reliably.

I also faced the problem, for some devices (my headphone atleast), it fails to establish a connection, I wrote this script to do the same, just disconnect for a moment, check battery, then connect back again (if you don't want to, edit it to add some, say a flag):

#!/usr/bin/python
import re
import sys
import os
from bluetooth_battery.bluetooth_battery import main
if __name__ == '__main__':
    os.system("bluetoothctl disconnect "+ sys.argv[1])
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    main()
    os.system("bluetoothctl connect "+ sys.argv[1])

And save it as 'bluetooth_battery' in ~/.local/bin... done :D

Exactly the same issue.

The thing is you dont wanna disconnect from the headphones as you are listening to a music.
