K700i and Acer BT-700 as HID

Hi,
I am using a Acer BT-dongle BT-700 (Soft.-version V1.32...) and a k700i
(SonyEricsson) handy.
Unfortunately it won´t work as HID for PPT-slides etc, as the option does
not even exist. (Handy is capable)
Higher software-versions don´t work with that acer dongle and Acer itself
does not provide recent
software.
How can I use the k700 i and my acer BT-700 as HID ?

Thanks in advance,
Marcus
