RFM69 or RFM12

I have working on RFM69Pi_V3.1.
In this board I use RFM12b instead of RFM69. Does it work? or I have to RFM69 module.

Yes, the RFM12B will work, but you must recompile the firmware with the correct switch to inform JeeLib that you are using the RFM12B, and you will not have the RSSI (received signal strength) indication.

So it will be better to stay with the RFM69CW.
