@paulsp I'm trying to get a Raspberry Pi gateway working as well. Also with a Bonnet but I don't think that is particularly pertinent as the bonnet doesn't do much other than connecting the RFM69 to a bunch of GPIO. Have you been able to get the Pi gateway working? Before I spend more time troubleshooting my own setup here and hack away further at the RFM69_new.cpp code it would be good to know whether I'm wasting my time, doing something stupid or not. If you got it working with only the changes you mention then that means I'm doing something wrong. Thank you!
