Can't get this to work either. Downloaded the release because I'm not touching any Rust tools, but it doesn't run.

  $ ./bluetui-x86_64-linux-gnu
  Error: Error { kind: Internal(DBus("org.freedesktop.DBus.Error.TimedOut")), message: "Failed to activate service 'org.bluez': timed out (service_start_timeout=25000ms)" }
