Description
channel 10, then
uSSID=Test_Network and
uChannelNo = 10
pScan_bitmap
Parameter to configure for which
channels passive scan is to be done.
For example, in 2.4 GHz, if only
channel 1 and channel 4 are required
to be scanned passively, then the
value for pScan_bitmap is calculated
as
Channel[n] Channel[n-1]
……..Channel[4] Channel[3]
Channel[2] Channel[1]= 000 …1001
Decimal for <000..001001> is 9.
Hence, the value of the parameter in
this case is 9
Similarly, in 5 GHz, if only channel 36
and 48 are required to be scanned
passively, then the value for bit_map
is calculated as 0000….1001. Decimal
for <000..001001> is 9.
This parameter controls which
channels are scanned passively. For
example, if pScan_bitmap=9 and the
“Scan “ command is issued with
uChannelNo=0, then all channels
except for channel number 1 and 4
will be scanned actively and these two
channels will be scanned passively (a
probe request will not be sent out).
The value of the Bit[9] should be „1‟
in the command Feature Select for
passive scanning to be executed.
