This is what I managed to do so far: https://github.com/hadess/bluez/commits/ble-battery A first (gentle) pass at a review would be nice, especially if there's a better way to get notifications on both the attributes in one go. The second question is how I would export this. I'm currently thinking that exporting a new interface on the device itself might be the best idea, and I'll monitor devices directly in UPower to export them to desktops. Would that be a good way? And as UPower will be the likely consumer of this data, I think I'll try mapping this set of flags: https://www.bluetooth.com/specifications/gatt/viewer?attributeXmlFile=org.bluetooth.characteristic.battery_power_state.xml to UPower properties rather than trying to export it as-is.
