I was looking for a newer and more supported way of collecting GATT information, rather than gatttool, which I understand to be deprecated. I was looking at bleak (https://github.com/hbldh/bleak) as a potential python-based wrapper. However, when I try to use it to collect information from an AppleTV which I can collect successfully with gatttool, it errors out with "bleak.exc.BleakDBusError: [org.bluez.Error.Failed] br-connection-unknown". I eventually tried the same thing with bluetoothctl and it gave the same-ish error of "Failed to connect: org.bluez.Error.Failed br-connection-unknown". So the difference seems to be that bleak/bluetoothctl try to connect to the AppleTV (which it rejects, if I don't go accept the pairing on the TV itself), whereas gatttool doesn't make a full connection/pairing attempt? The bleak developers said that this is a limitation of the DBUS API, and that there's no way to get GATT information without a connection. Is that correct? Cheers - Jake
