Ralink is not good for supporting this type of setup. I had tried AP and
client mode, and after some hacking it sort-of worked.
From my notes:
ifconfig: SIOCSIFFLAGS: Device or resource busy. Looking at the output
of 'iw list' the valid interface combinations only listed AP and mesh
mode, not Station/Managed mode. On further investigation, none of the
Ralink chips are fully supporting AP+Sta mode. After forcing the driver
to report that it can support the combination, I was able to configure
both interfaces as desired. The hack gives the following combination
output:
Pre:
valid interface combinations:
* #{ AP, mesh point } = 8,
total = 8, #channels = 1
Post:

* #{ managed, AP, mesh point } = 8,

You may wish to force add 'adhoc' (P2P?) mode, and see how far it gets
you. This was on an RT28xx USB device, so you may have more success on
others.
Hack (for test) looked like:

#ifdef CONFIG_MAC80211_MESH
if_limit-types |= BIT(NL80211_IFTYPE_MESH_POINT);
#endif
A nice Atheros (AR9330) shows good support for combinations:

point, P2P-GO } = 8,

Maybe I asked the wrong question
I want to run a mesh like batman. The examples on the batman site
should it being run in adhoc mode. Can I instead run it in mesh mode?

Nope, mesh mode in this context refers to 802.11s which implements a
mesh network in a lower layer than batman-adv,
already providing a layer2 link-local domain between all participating
nodes.
running batman-adv over that is redundant and probably troublesome
so: choose between batman-adv over adhoc interfaces,
*or* use plain mesh mode interfaces.
If you're deploying this today, in a non-experimental scenario, you
probably want to go the batman-adv way (and drop ralink :P); open11s is
a younger project and while i'm impressed by the development pace, still
lacks some key features (IMHO) like multi-interface support :(
Cheers!

Re: [OpenWrt-Devel] Multiple virtual wireless interfaces - mix adhoc and ap mode?
So how do you want batman-adv and allow normal clients to attach?
Maybe I should give 11S a try.
I loaded OpenWRT onto my AR9331 hardware It doesn't support mixing
adhoc (IBSS) and AP mode either.
valid interface combinations:
* #{ managed, WDS, P2P-client } = 2048, #{ AP, mesh point, P2P-GO }
= 8, #{ IBSS } = 1,
total = 2048, #channels = 1, STA/AP BI must match
* #{ AP } = 1,
total = 1, #channels = 1, STA/AP BI must match, radar detect
widths: { 20 MHz (no HT), 20 MHz }
