Needing more pins, I moved my RFM69 from my Arduino Uno to my Mega 2560 using the same hookup and code as in your guide.
It appears to no longer be receiving.
I only use this node to receive.
Please help if you can.
SPI is in a different place on the mega, you need to move over to those pins for the device to work.
Thanks for your reply. Now that I know what I am looking for, I have come up with this:
// RFM69 uses different pins on the Mega.
// MISO - pin 50
// MOSI - pin 51
// SCK - pin 52
// NSS - pin 53
// DIO0 - pin D2
A quick test appears to show that the problem has been solved.
Glad I could help!
