问题
I am interested in scanning only a particular set of frequencies for a particular time interval (this is different from scanning interval in android api). Is there any high level api
or
user to kernel space communication interfaces, mechanisms (sysfs,iotctl,mmap etc.) (in a rooted device) that can allow me to specify the set of frequencies to be scanned for a particular interval of time. If I understand correctly the device supplicant carries this information?
Would very much appreciate if anyone can point me in right direction.
Thanks in advance!!

See my answer on android.sx. Basically, install iw on your device and then call:
iw dev wlan0 scan freq 2417
However, I do not know how this interacts with the supplicant/connection manager. We use it to measure RSSI only.
