RF communication 868 MHz between 2 arduino

Hello, I am currently working on a school project and I have to make a communication on the 868MHz RF band between 2 arduino boards (both transmit and receive information). I chose UNO card and module: http://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_92&products_id=2169 But for programming I don't know what library use because VirtualWire is made for 433MHz ... And if this module is the only connect to the SPI bus, is it automatically at 0x00 adress? If someone has already done this kind of communication I would like to see what the code looks like because I started in Arduino. Thank you in advance

Wireless module is connect on SPI bus, so how does it work? If someone has already done this kind of communication I would like to see what the code looks like because I started in Arduino.

The VirtualWire is only for modules that use on/off (ASK) modulation. It can be used for any frequency.

Your module has a protocol inside a chip. The chip is the NRF905. Read a datasheet of that chip to see what it can do. That chips takes care how the RF signal is modulated and takes care about the protocol. But you need to initialize it. These chips are not easy to program, so you need a library. That is why a library is available on that elechouse page.

The SPI interface uses no addresses. Each device has its own chip-select line, and shares the clock and serial input and output data lines.
