      If I request requestConnectionUpdate the parameters are not changed which can be controlled via btmon or via /sys/kernel/debug/bluetooth/hci0/conn_max_interval. Furthmore the signal connectionUpdated is not emitted.

      So how does it work? Thanks in advance, and kind regards,

        @abeat Did you check whether you get any errors: https://doc.qt.io/qt-5/qlowenergycontroller.html#error-1 ?

          No sorry there is no error message at all. Under mac os I receive a not implmented but under linux / bluez where it should be implemented I received nothing. But I've could solve it by forcing my device to update the connection interval to the minimum.
