INSYS WLAN serial 2.1 Overview AT Commands
Command Description
AT#GW=<IP ad-
dress>
Set gateway address
The standard gateway is set with
AT#GW
. This setting is used by remote IP ad-
dresses, which can only be accessed by routers, not directly.
IP packets, which cannot be sent to the local network (defined by
AT#IP
and
AT#NM
), are sent using the address set by
AT#GW
for forwarding.
AT#GW
is used in connection with
AT#NM
to establish a connection via a router.
If a router is used,
AT#GW
and
AT#NM
must be set to enable a data connection
via the router.
Factory setting:
AT#GW=0.0.0.0
IP address, gateway and network mask must be coordinated in the local net-
work segment.
The setting can be queried with
AT#GW?
.
This setting is immediately stored in the permanent memory (independent
from the command
AT&W
). It will only take effect after a restart.
