Bluetooth Device offline

[ITCMD]

OS: Lubuntu with latest updates
Bluetooth device: iHome speaker

When I run your script it gives the following output:

$lucas:~$ ./bl_battery.py FC:58:FA:EA:74:FC
FC:58:FA:EA:74:FC is offline

However the device is certainly online, I'm playing music from it now. Here it is on here:

Any ideas why this is happening?

Disconnect the device then run the script again. Does it show the same error?

[ITCMD]

No. When I disconnect it waits for a while and tells me it cannot connect, or something. I can give you the exact message if you would like. I would also like to note that when it tells me that the device is offline it does so instantly after I run the command.

I'm facing the same problem here :/

I did this but still doesn't work.

This fork of the project prints the debug logs: https://github.com/clst/Bluetooth_Headset_Battery_Level

You can try it and send me the output.

will do thanks @TheWeirdDev

You can try changing the port number in line s.connect((BT_ADDRESS, 3)) from 3 to other numbers (0 to 9) and check if that works. Because it is device specific and varies from device to device.
If that didn't work either, your device is unsupported.

I checked numbers from 0 to 9. Nothing worked.

Your device does not support this protocol.

Which protocol? Showing battery status? I'm using JBL E45BT. When I connect it to Android phone I see percentage of power in headphones battery.

This script uses AT commands to communicate with Bluetooth devices. Some devices support this commands, some don't.
If your headset uses a different way to communicate, you have to find another way to check battery status. I can't help you with that.
