scan <time> <P>
Performs an active probe scan of access points on all 13 channels.
Returns MAC address, signal strength, SSID name, security mode.
Default scan time is 200ms / channel = about 3 seconds.
time
is an optional parameter, this is the time in ms per channel.
For example, “scan 30” reduces the total scan time down to about 1
second. This command also works in ad-hoc mode. If the optional
P
parameter is entered, the module will perform a passive scan, and
list all APs that are seen in passive mode.
sleep
Puts the module to sleep mode. The module can come out of sleep
mode by either sending characters over the UART or by using the
wake timer.
time
Sets the Real time clock by synchronizing with the time server
specified with the time server parameters (see section 5.9) This
command sends a UDP time server request packet.
