Unfortunately our chip is not Intel nor Atheros and the chip vendor suggested 
that with one supplicant this use case can't be fulfilled.

Thanks for this information, we will sure use this script to see if we are able 
to create two GO with one supplicant.

This should work with one wpa_supplicant, unless the chip vendor's driver is 
weirdly done.
Afaik, intel or atheros work properly, but if it's none of those... ;)

In ConnMan side that's another story, you would need to tweak still quite some 
stuff to enable that.


In any case, having ConnMan in the picture brings some work: if you have 
2 wpa_s, you will need to
change some stuff to make it work (and it's ugly as hell), if you have 2 
wpa_s and 2 connman... same thing (and it's ugly too).

The very best solution would be one wpa_s and one connman, as usual.

In connman repository, there is a q&d test script for wpa_supplicant 
dbus interface, for P2P named p2p-on-supplicant
Try playing with it, creating more than 1 GO.
Then you will know what's needed (well, mostly) to do in ConnMan.
