The MOB-IP-SIM™ Manager Windows utility should be used to set up the MOB-IP-SIM™ on your network in most cases. However, if the software utility is not available, the simulator may be manually configured by using a terminal emulator software application such as Hyperterm to send AT commands directly to the serial port located on the MOB-IP-SIM™ back panel. The COM port should be set to 9600 Baud, 8 bits, no parity, and 1 stop bit.
To determine the current DHCP configuration enter at+ipdhcp?
A response of
+IPDHCP: 1 OKindicates that DHCP is in use. A zero indicates a static configuration.
Enter at+ipdhcpaddr? In this example, a response of
+IPDHCPADDR: 192.168.1.210 OKindicates that the assigned address is 192.168.1.210.
If the configuration is indicated to be static then enter at+ipgw? A response of
+IPGW: 192.168.1.1 OKindicates the gateway in this case is 192.168.1.1. To retrieve the ipmask enter at+ipnetmask? A response of
+IPNETMASK: 255.255.255.0 OKindicates that the ipmask is set to 255.255.255.0 in this case.
To reconfigure a static IP address, set only the values that need changing, then enter +ipdhcp=0 even if it was set to 0 already; this makes the new settings take effect.
For DHCP IP address assignment, set +ipdhcp=1 and (optionally, but most likely useful) confirm the new address by entering at+ipdhcpaddr?
+IPDHCPADDR: 192.168.1.210 OK
