Enabling both normal wifi and wifi hotspot to get RSSI values of wi-fi hotspots
What you probably want is your phone work as adhoc and as an AP at the same time I guess it's called bridging

I don't think that at first android phones support the adhoc mode at all yet.

The bridging is only possible for normal wifi routers not for android phones. Routers also support WDS http://en.wikipedia.org/wiki/Wireless_distribution_system
There's no such thing as WDS for android phones yet AFAK.



hope it clarifies the matter abit. thanks.
