What does a relay node need to change from a message payload before repeating it, beside the hop count ?
From what I understand so far, a relay needs to listen to a LoRa channel for incoming packets, then filter Meshtastic messages, and repeat them decreasing the hop count. In this case, it should be possible repeat messages whose payload can not be decoded, isn’t it ?
BTW, for those interested, here are some thoughts about more clear separation between LoRa channels and Meshtastic channels : Encryption / Secondary Channels - #9 by Eagle
