2 General Operations
This chapter describes the use cases for generic operations as required by Serial to Wireless
Application.
• IP Configuration, page 11
2.1 IP Configuration
2.1.1 Static IP Configuration
2.1.1.1 Use Case 1: Static IP Configuration
Description In this use case, 192.168.45.3 is used as fixed IP address to configure the Telit node in
station mode.
Prerequisite NA
Precondition NA
Setup Architecture The setup requires an AP (router) and a Telit node which act as Station, where the Station
connects to AP and uses a user defined IP address.
Procedure Following commands are used to configure the static IP address in station mode.
at+WNI=0 // for station mode
at+WNIPC=0,1,192.168.45.3,255.255.255.0,192.168.45.1

2.1.2 DHCP Server
2.1.2.1 Use Case 1: Start DHCP Server
Description To configure Telit node in AP mode and enable DHCP server, where the client associates
to the node and obtains an IP address automatically.
Prerequisite NA
Precondition NA
Setup Architecture The setup requires two nodes, where one node act as AP and another act as STA. These
nodes connect to the AP node and obtain IP address specified by the DHCP server in AP
node.
Procedure Following commands are used to configure DHCP server AP mode, where the node is in
AP mode and starts the DHCP server specifying the IP address to the client within the
specified range.

Description NA
Prerequisite NA
Precondition NA
Setup Architecture NA
Procedure Following are the steps used to configure WL865E4-P module in concurrent mode.
Enable New AT Commands by using AT+YLC=0.
2.Initial NCM for STA mode by using the command AT+WNI.
3.Connect the module to the Access Point of SSID - “Telit_Demo”, channel – 6 and
Passphrase – “Telit123” by using command AT+WNCN.
4.Initial NCM for AP mode by using the command AT+WNI.
5.Set the static IP configurations for AP (IP address, subnet mask and Gateway) as
192.168.240.1,255.255.255.0,192.168.240.1 by using AT+WNIPC command.
6.Set the range of the IP address as 192.168.240.10 – 192.168.240.25 and DHCP lease time
– 8640000(seconds) by using AT+WNAPIPC command so that connected stations will get
IP address in the range.
7.Set SSID, channel, security type, Encryption type and passphrase by using command
AT+WNCR.
8.Start Web Provisioning server b using the command AT+WNWEBPROV.
9.Issue AT+WNIFCFG to get the current configuration of different interfaces
AT+YLC=0
AT+WNI=0
AT+WNCN=1,"Telit_Demo","Telit123"
AT+WNI=1
AT+WNIPC=0,1,192.168.240.1,255.255.255.0,192.168.240.1
