Have you seen the "radiohead" library by Mike McCauley at http://www.airspayce.com/mikem/arduino/RadioHead/
He has made a library for the various Hope RF products that works on Arduino. There are also files in the latest release that allow the radiohead library to be built for the STM32F4 chips. I do not know the level of effort that it would take to port the libraries but it is at least an example of working code.
