How many "hops" can lora do?

Just wondering how many times a message can be repeated across a mesh network.

This protocol maxes out at 7. But it is really more limited by all nodes only having one radio (which is a fine choice for cost and complexity reasons).

The sending node specifies a Max hops per packet and currently picks 3 for that value. Because given the long range of the radios and the initial use case that makes sense (given that we mostly use naive flood routing).

I’ve promised @CycloMies an updated version of the protocol doc this week. And he will further improve it.

So three is the limit for now, but 7 might be in the near future?
