The results of a most recent scan are available by calling
getScanResults, even if your application didn't start a scan, that's
probably the best you can do without initiating a scan.
However, if there is an active connection, then AFAIK, Android doesn't
initiate scans on its own. If there is none, and WiFi is enabled, it
does periodic scans looking for known networks, but not as often as 5
seconds.
Also scanning, I believe, is an explicit process that has to be
initiated with the WiFi radio chip, it doesn't just happen as a side
product of it being enabled.
So - in short - no. If you need to reliably get surrounding networks,
you've got to initiate scanning, or rethink why you need it so often.

Hi,
Is it possible to get the RSSI of surrounding wireless networks
without doing a full scan? I need periodic updates about surrounding
networks perhaps every 5 seconds. Can't do a scan that often. Using
aidl would work if the info is available anywhere.
