@robvk said in MySensors 2.3 and RFM69 new driver. Problems and solutions: #define MY_PASSIVE_NODE Oh no I totally missed this line! This statement disables ACK and other transport-related stuff. Case closed.

@Koresh Intresting option: to generate a full reset if no sign of life for ... time limit. I would implement this without special library/ MySensors functionality. Just use gw.sleep( xx ms) ; and generate a pulse every xx ms in the main loop.
