bluetoothctl set-alias - how to select the device

[Dave Mielke]

Hi:

It isn't clear to me how bluetoothctl set-alias decides which device to rename. From a bit of a look at the code, it seemed like it might be the most recent connect, but that proved to be an incorrect conclusion. In the same way that select can be used to pick the active controller, is there a way to explicitly pick the active device?

It only works while connected currently, we could in theory extend the
command to have an optional 2 parameter so one can enter an address.

Even then, it's unpredictable when more than one device is connected. In my case, for example, it can be my Bluetooth speaker as well as a braille device. I assumed, at first, that maybe it's the most recently connected device, but that, too, wasn't true. When I connected the second device it still changed the alias of the first device.

That, I think, would be very helpful. As I understand it, isn't set-alias only updating local (host-resident) data anyway? Also, given that set-alias isn't predictable anway when more than one device is connected, I think there definitely needs to be a way to explicitly say what one is wanting to do.
