The Button update over Wi-Fi can only work if the Base Unit updates are performed incrementally.
After installing the new firmware on your Base Unit, the ClickShare Buttons will automatically be updated over Wi-Fi while plugged in into a laptop (and not sharing).
The Button update can of course also be done by pairing them to a Base Unit USB port (or by using the Button Manager), but this is not required after a regular firmware update.
Button Manager currently does not work with the C-series/CX-series Buttons.
