INSYS WLAN serial 2.1 Overview AT Commands
Command Description
AT&S<n>
DSR behavior
AT&S0
DSR is always active (default)
AT&S1
DSR follows DCD, e.g. DSR is only active for existing connec-
tions
AT#SCAN
Selection of access points
The command
AT#SCAN
indicates which access points may be received. The
found APs are output as a list. The channel, the signal strength, the MAC and
the SID are indicated in plain text. The symbol "*" after the MAC address indi-
cates APs with encrypted sending (WEP or WPA).
AT#SSID=“<ssid>“
Define SSID
AT#SSID=“WLANDEMO“
(default)
The setting can be queried with
AT#SSID?
.
In WPA mode, the WPA master key must be recalculated when the SSID is
changed. The pre-shared key PSK must be reentered using the command
AT#PSK .
This setting is immediately stored in the permanent memory (independent
from the command
AT&W
). It will only take effect after a restart.
AT#STAT
Display status
AT#STAT
displays the current status of the WLAN connection:

Used channel


tion and the positioning of the antennas in a way that SNR
≥ 20 dB.

The MAC of the access points, with which a connection is currently estab-
lished
AT#TEL=<n>
Telnet port for remote configuration
AT#TEL=<n>
determines the remote configuration port via Telnet for the
TCP/IP port:
AT#TEL=0
deactivates the access
AT#TEL=23
factory default for Telnet
During remote configuration, all
AT
commands can be entered, so a remote
firmware update (
AT**
) or establishing a connection (
ATD
) is also possible
remotely.
The user name and password are defined via
AT#TLU
and
AT#TLP
.
The setting can be queried with
