I recently bought a multifunction speaker, which can connect using bluetooth. The device is listed as S2025 in bluetooth settings (see the image below), but the connection is greyed out (OFF). The speakers usually sound "Bluetooth connected" when connected using android smartphone it functions properly. I have already tried a few things searching solution to similar question on askubuntu such as installing bluez:i386 package.
Following is the output of some of the commands in terminal
rfkill list
