You do not need to configure the SSID of your network since that is done from the
access point names.
Now configure the access to the two access points.
// First Access Point
#define AP_0 "test1"
#define AP_0_LEN strlen(AP_0)
#define MY_ADDRESS_0 "10.10.6.250"
// use this static IP when connected to AP 0
#define PING_ADDRESS_0 "10.10.6.1" // address on AP 0 to ping
#define KEY_0 "0123456789abcdef0123456789"
// Second Access Point
#define AP_1 "test2"
#define AP_1_LEN strlen(AP_1)
#define MY_ADDRESS_1 "10.10.0.99"
// use this static IP when connected to AP 1
#define PING_ADDRESS_1 "10.10.0.50"// address on AP 1 to ping
#define KEY_1 "0123456789abcdef0123456789"
#define IFC_WIFI_SSID AP_0
#define _PRIMARY_STATIC_IP MY_ADDRESS_0
Modify the access point names and keys to match your access points and network.

WIFIPINGYOU.C
—sends out a series of pings to a RabbitCore module on an ad-hoc
Wi-Fi network.
This sample program uses some predefined macros. The first macro specifies the
default TCP/IP configuration from the Dynamic C
LIB\Rabbit4000\TCPIP\TCP_
CONFIG.LIB
library.
#define TCPCONFIG 1
Use the next macro unchanged as long as you have only one BL5S220. Otherwise use
this macro unchanged for the first BL5S220.
#define NODE 1
Then change the macro to
#define NODE 2
before you compile and run this sample
program on the second BL5S220.
The next macros assign an SSID name and a channel number to the Wi-Fi network.
#define IFC_WIFI_SSID "rab-hoc"
#define IFC_WIFI_OWNCHANNEL "5"
Finally, IP addresses are assigned to the RabbitCore modules.
#define IPADDR_1 "10.10.8.1"
#define IPADDR_2 "10.10.8.2"
As long as you have only one BL5S220, the Dynamic C
STDIO
window will display
the pings sent out by the module. You may set up a Wi-Fi enabled laptop with the IP
address in
IPADDR_2
to get the pings.
If you have two BL5S220 boards, they will ping each other, and the Dynamic C
STDIO
window will display the pings.
