I realized there is an issue within the wire format: LoRa chips allow to ignore packets aimed to other nodes (ignore means stopping signal reception and avoiding issuing any interrupt signal to the MCU) by configuring a NodeAddress and enabling filtering flag.
However there is a restriction: the node address first byte must be at payload beginning, but at the moment the first byte is used for "[IFAC Flag], [Header Type]" so NodeAddress filter cannot be used, and nodes are woke up every time a message is aired in the neighborhood.
This is a very important feature for low power configurations, since it might enable standby/wakeup and other similar patterns.
