Example 3, Static IP Address and TCP Listener
Example 4, Find the DHCP Assigned Address and RSSI Value
The OWSPA311g can be configured to listen for incoming TCP and/or UDP connections on a
specified port. This example shows how to configure the module for this purpose and how to
make sure the connection works. It also shows how to use static IP settings instead of dynamic
settings which was used in the previous example.
This example describes how to find out what IP settings the module is assigned when config-
ured to use DHCP IP settings. The default behavior of the OWSPA311g is to disconnect all peers
including the link layer (WLAN link) when AT mode is entered. Effectively this will release and
flush the assigned IP settings as soon as the module enters AT mode, which makes it impossible
to read out these settings. However, there is a way to change this behavior, so that the peers
and link layer are kept connected when the module enters AT mode. This method also applies if
you want to find out the RSSI value for the link layer connection.
The example requires the module to have valid WLAN settings (see Example 1, Configure a
WLAN Connection) and at least one remote peer configured (see Example 2, Enable DHCP and
configure a Remote Peer).
7. The module will now restart and associate with the access point. When associated it
1. Connect to the module and enter AT mode.
2. Setup WLAN configuration settings (see Example 1, Configure a WLAN Connection).
3. Set the static IP address, netmask and gateway settings with the AT command
4. Turn on the TCP listener and set it to listen on port 5003 with the AT command
5. Restart the module with the AT command AT*AMWS=0,0,0,0,1,0
6. The module will now restart and associate with the access point. It will use the config-
