Internal Nokia comment:
"If a device doesn't have a name then of course it is empty."
Those no-name device(s) are not mine and I can't control them. For a user,
Wwhen scanning for devices and just getting a bunch of empty buttons (no icon,
no explanation) visually it looks like something is wrong, IMO.
Displaying a generic bluetooth icon or displaying the hw address would make it
clear that there is a real device behind the button.
I totally agree. This has to be resolved in the internal UI Specifications for
Harmattan (the version after Maemo5), hence moving Product to Specs.
For Maemo5 this is a WONTFIX as the Maemo5 UI is considered stable by Nokia.
This issue has been FIXED for Harmattan (the software version after Maemo5).
Bluetooth UI Spec says now:
"Bluetooth devices view
Unnamed device: Label to be shown instead of Bluetooth device name if device
name is empty."
According to Nokia UI changes are a WONTFIX for Maemo5.
