Connection refused for BLE_ATH-M50xBT

[Vrizkag]

bluetooth_battery 00:0A:45:0B:5C:5C
00:0A:45:0B:5C:5C is offline [Errno 111] Connection refused

Then i tried this:

bluetooth_battery 00:0A:45:0B:5C:5C.1
00:0A:45:0B:5C:5C is offline [Errno 16] Device or resource busy

Before that, I went into bluetoothctl to get the correct address

[BLE_ATH-M50xBT]# info

I'm not sure what's the reason. Disconnect your device first, then run the script again while disconnected. This works for some devices.

[cheriimoya]

did you try to rerun the script @Vrizkag? like in executing the same command twice?
i.e.

$ bluetooth_battery 00:0A:45:XX:XX:XX
00:0A:45:XX:XX:XX is offline [Errno 111] Connection refused

$ bluetooth_battery 00:0A:45:XX:XX:XX
Battery level for 00:0A:45:XX:XX:XX is 80%

Got the same problem using different device, let me know if you rather have a separate issue for this 876964 headset.

( 876964 is this headset model name 🤷 )

With the headset connected (script exits in less than 1s, it returns this error every time I run it):

╰─ bluetooth_battery E9:08:EF:93:XX:XX
E9:08:EF:93:XX:XX is offline [Errno 111] Connection refused

With the headset disconnected

╰─ bluetooth_battery E9:08:EF:93:XX:XX
Couldn't find the RFCOMM port number
E9:08:EF:93:XX:XX is offline [Errno 112] Host is down

Same error with a Bose quietcomfort 35.

The command journalctl -f -o cat /usr/bin/gnome-shell prints out:

Bluetooth battery indicator: 28:11:XXXXXX is offline (16, 'Device or resource busy')
Bluetooth` battery indicator: 28:11:XXXXXXis offline (111, 'Connection refused')

I have the same issue with my headset, I'm on Ubuntu 20.04.2

I have the same issue on Ubuntu (5.4.0-89-generic #100-Ubuntu SMP) with a Bowers & Wilkins headphone. Battery level is reported correctly after a reboot, but after the first suspend I get the same behaviour ("Errno 111") as described above.

Oh, and I found these lines repeated over and over in /var/log/syslog:
Oct 12 20:37:01 XXX gnome-shell[6989]: Usage of object.actor is deprecated for Indicator#012get@resource:///org/gnome/shell/ui/environment.js:287:29#012_refresh@/home/axel/.local/share/gnome-shell/extensions/[email protected]/extension.js:80:13#012_runLoop@/home/pipapu/.local/share/gnome-shell/extensions/[email protected]/extension.js:47:14
Oct 12 20:37:02 XXX gnome-shell[6989]: Bluetooth battery indicator: Battery level for B0:67:2F:1B:A9:6D is 100%

So, actually the battery level is correctly reported by the device. Perhaps the deprecate warning is not correctly interpreted by bluetooth_battery?

[talhajunaidd]

I can confirm that after a restart, battery status is reported correctly
