Reading this thread I could capture the battery level of my bt devices on my laptop. But is not working on my desktop with the same devices, because upower (and/or DBUS I suppose) doesn't recognize them, bluetoothctl does.

Ubuntu Mate 22.04 Kernel 5.15.0.60

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
