Last time I played with Moremicro they didn't work with real 802.11s and had some hokey proprietary hierarchal tree topology that required a main basestation gateway. ad-hoc, peer-to-peer was broken. They finally fixed their driver?

I believe yes, give them other try, my scenarios with one connected station and mesh on drone platforms works out of the box

The tree mesh thing you're thinking of is actually just EasyMesh (it's a standard!). We're using prplmesh.

But yes, 11s Mesh also works. Let us know on the forum (https://community.morsemicro.com/) or via github (https://github.com/MorseMicro/) if you're having issues. Err, I work for Morse in case that wasn't clear.
