5.3.4 Scanning
This command is used to scan for networks with the specified parameters and displays the
results. Scanning can be performed to find networks with specific SSID or in a particular
operating channel, or a combination of these parameters. Scanning for a specific SSID
employs active scanning, in which probe requests are transmitted with the SSID fields
being filled appropriately.
Command Syntax AT+WS[=<SSID>[,<BSSID>][,<Channel>][,<Scan Time]]
Parameter Description
Table 86, page 111 describes the Scanning parameters.

Parameter Optional/Mandatory Value Description
SSID Optional N/A
A string containing ASCII characters

When SSID is specified, the GS node only
scans the configured SSID.
BSSID Optional N/A
This command does not support scan based
on the BSSID.
Channel Optional N/A
If channel is specified, then the node scans
only that particular channel, else it scans all
valid channels based on configured reg
domain.
Note: Maximum Scan per channel is 20.
Scan Time Optional
5-1200 (milliseconds)
150 (default)
(see 5.3.1.1 Set Scan Time, page 100 )

is obsolete.
The recommended method to set scan time
per channel is by using AT+WST command
(see 5.3.1.1 Set Scan Time, page 100 ).
