When trying to manually connect to a known BT device this message is shown which is not human readable. Maybe you could show something more comprehensible.

Thanks!

Error messages in ManagerDeviceMenu.py are not exactly human readable and kinda misleading as well. :(

E.g. "Host is down", "br-connection-page-timeout"? What's the "host"? Is it my laptop? Is it its Bluetooth adapter? Is it the device I'm trying to connect to?

Also, to me it makes sense to show a human readable code as well as a low level original code, so that it would be easier to track it down because it actually comes from https://github.com/bluez/bluez

So, it would be great if you showed something like:

Failed to connect br-connection-page-timeout: Timeout initiating a connection with the remote device br-connection-profile-unavailable: The remote device does not support the selected protocol

Maybe these messages should be reported to upstream instead considering your merge request, dunno.

Not sure what you mean. Where do you get to see Host is down?

That's the code where we catch the bluetoothd / libc error message. The message we show in the UI for it is Device did not respond.
