Hi, Thank you for efforts on creating this library. I am using a RFM69HCW module (868MHz -- not the moteino version) and Arduino Uno as the Gateway of my system. In Void Setup, there's this line : " radio.promiscuous(promiscuousMode); " And for that line there's this error : " 'class RFM69' has no member named 'promiscuous' "
I would appreciate your help on solving this issue.
