If you got that far, the scan "should" work. ;) My main guess is that
your device is not calibrated properly (the NVS that Shahar provided is
a "default" one and may work, but the results will vary wildly depending
on your RF).

Which device are you using? If you bought a end-user device, you may
find the appropriate NVS lying somewhere in the filesystem.  If you're
working on a new device, you will need to get it calibrated.
Unfortunately we don't have a publicly available application to do that
yet (but there's one under work).

Please send the debug information to us and we may be able to figure
something out from the logs.  You probably don't need DEBUG_SDIO,
because that one will dump a *lot* of stuff that will probably not help
here...
