Are there any docs that talk about what B.A.T.M.A.N. V vs B.A.T.M.A.N. IV is good for? The decision to upgrade was made before I got here, I'm not sure anyone understood that IV would still be supported/expected to be used.
There is a summary page about B.A.T.M.A.N. V [1] which you should read first. And you should definitely not use B.A.T.M.A.N. V when the "throughput based metric" is not able to retrieve any meaningful values for your link partners and you are not able to give the routing protocol anything useful to work with.
And B.A.T.M.A.N. IV is still the default and cannot be compiled out. And the configuration option for B.A.T.M.A.N. V still has following sentence at the end:
B.A.T.M.A.N. V is currently considered experimental and not compatible to B.A.T.M.A.N. IV networks.
So while it is definitely less experimental than some years ago, it tends to still have problems to get useful throughput information from the drivers of the lower device(s).
But both protocol versions have their Pros and Cons - but with your current setup (with your current drivers), I have have big doubts that B.A.T.M.A.N. V has any benefits for you. But I could be wrong.
Kind regards, Sven
