Yes, that was my conclusion.I was only thinking that a year-old experimental firmware might have bugs in it that were fixed in the current release, that's all. But it sounds like that's the only version that supports repeater mode.
Now that's an interesting idea. I may well give that a go, but I'm good for now.If you're only using it as a repeater then you're not really using any other "enhanced features". So I guess the alternative would be to use stock or the current Gnuton firmware in an AiMesh setup with one device as a node rather than a repeater. Whatever works best for you.
Thanks again!
