RFLink in 868 Mhz

[Surfy57]

Hello everyone,

I build a RFLink in DIY in 433 MHz with an Arduino Mega 2560.
Everything works perfectly, both for the emission and the reception.

I would now like to use the 868 MHz frequency, but I can not find anything about that with the RFLink,
I am trying to know that transmitter / receiver, as well as a wiring diagram.

Is it possible to use the same Arduino Mega 2560 for frequencies 433 and 868, or is it needed for each frequency?
Which pins to use for the 868?

RFLink supports the ZigBee protocol?

Thank you in advance
Have a nice day

The RFLink board allows for either 433.920, 433.420 or 868.3 Mhz modules. You cannot attach them all, you will need another board/Arduino to attach it using USB. You can however attach the 2.4Ghz module next to any of the other 3. Not too sure about the ZigBee protocol though! Anyone?
