Comment 30 for bug 1798400

Noticed that in the forthcoming LibO 24.2, the "remote" is being given prominence, by moving its settings from the Tools ▸ Options ▸ LibreOffice Impress configuration dialog to the Slide Show ▸ Slide Show Settings menu.

IMHO this makes it quite important to have this feature working as intended on all the supported platforms.

The remote is meant to work either with a WIFI connection or a Bluetooth one.

The current bug is about the Bluetooth connection.

Bluetooth Connection
--------------------

As of today, because of the issue at hand, the Bluetooth connection is completely unusable on standard Linux distributions that use Pulseaudio (a detailed discussion why is in the previous comments).

Notwithstanding the fact that this but is about the Bluetooth connection, I am providing also a few notes about the Wifi connection to highlight why the Bluetooth connection is so important and should be fixed.

WIFI Connection
---------------

Unfortunately, the WIFI option is practically unusable in almost every professional working environment, including universities and conferencing sites. This is because in all these environments the network is completely out of the user control, restricted in any possible way, heavily firewalled, with the wifi framework consisting of multiple access points under the same SSID. In a similar arrangement the possibility of the remote to reach LibO at a non-standard TCP port is erratic if not negligible.

The impossibility to use the WIFI connection precisely in those real world environments where the usage of the remote would be most important is the reason why a working Bluetooth connection is needed.

Note that in practice the WIFI connection situation could be improved by suggesting the possibility to let the presenter laptop connect to the internet via the mobile phone hotspot. This would need the remote app to try to connect to LibO not just via the phone default interface, but also on the network used for the hotspot.
