1./ In LMS (Logitech Media Server) activate the "Remote Music Libraries" plugin. In the "Remote Music Libraries" settings, navigate to "UPnP/DLNA Client" and select "Enabled". This will allow you to discover other UPnP/DLNA media servers.
2./ Install package: Java runtime, Unzip, BubbleUPnP Tether Client, SSH Putty command:
wget -O - https://raw.githubusercontent.com/lovehifi/lmsbub/main/install-archlinux.sh | sh
3./ WinSCP edit config (or nano edit): /opt/upnp/bupnp.service Add username, pass, URL server
ExecStart=/opt/upnp/launch.sh -connect http://yourserver:58050 -login yourusername -password yourpassword
4./ Run bupnp.service, SSH Putty command:
sudo systemctl daemon-reload
sudo systemctl restart bupnp.service
sudo systemctl status bupnp.service
You can connect to the BubbleUPNP Server either through the Internet or locally to access and listen to your music. Wait a few minutes for LMS to display the available servers.
