Solved the issue, I was using a custom PCB I had fabricated and the MOSI connection was not soldered properly.

Had a look at your code and the only thing I spotted was in the frequency you had RFM69_915MHZ where as I was using RF69_433MHZ... I missed the M.

Tried again and still issues. Here is my monitor output, I am using the PassiveNode example sketch.

The tutorial doesn't mention anything about wiring the RS but I know on the adafruit version of RFM69HCW, you do need RS wired.

Hi, first post here. I followed the tutorial to get RFM69HCW working on a raspberry pi and have set one up as a gateway.

I am now trying to get the RFM69HCW working with an ATMEGA328P
I have checked the wiring and I have D0 going to PIN 2 of the ATMEGA328P

In MySensors sketch, do I need to change anything?

I have changed the following
// Enable and select radio type attached
//#define MY_RADIO_NRF24
//#define MY_RADIO_NRF5_ESB
#define MY_RADIO_RFM69
//#define MY_RADIO_RFM95

and I also added this

#define MY_RFM69_FREQUENCY RF69_433MHZ
#define MY_IS_RFM69HW
