Within bluetoothctl session (running in a balena terminal window for the pulseaudio-server service): using the command info <mac address> gives information on the bluetooth device, but it doesn't show the device name - instead it shows again its MAC address.

Strange enough when successfully connecting/pairing/trusting the device, from then onwards (also after reboot of balena device) the info command is always correctly showing the device name.

The below log file shows both an example of a device for which info didn't return a name and one for which info did return a name.

apparently you should first pair the device in your bluetoothctlsession. Once this is done, the name is returned by the infocommand.
