RCM4400W Wifi Help

Rabbit
1

Can any kind soul out the post a working example of how to connect a RCM4400W to an access point, either with or without WEP.

The examples provided with the Dev Kit are next to useless. Scanning through tcp_config.lib I see #defines for WIFI_INIT but none of the examples use this. In fact no source file provided with Dynamic C 10 uses this macro. How do the examples initialise WIFI ?

Any help would be gratefully received.

Hi,

I installed the DC 10.11 and WPA BETA lib and was up and running in no time. All I did was to include the following lines at the top an existing TCP/IP samples and hey presto, it worked.

#use RCM44xxW.lib

#define TCPCONFIG 1

#define _PRIMARY_STATIC_IP “192.168.0.58”

/*

  • It is necessary to define these to include WPA support.
    */
    #define WIFI_USE_WPA
    // Bring in WPA support
    #define _WIFI_WEP_FLAG WIFICONF_WEP_TKIP // Define cypher suite
    #define RAND_USE_MD5
    // This is highly recommended

/*

  • ASCII passphrase generation requires not only the passphrase itself,
  • but also the correct SSID with which it will be used. Thus, it is
  • particularly important to give the correct access point SSID here.
    /
    //    ****** identify ID of Wifi network - mine was wetley1 *********
    #define _WIFI_SSID “wetley1”
    /*
  • Define an ASCII passphrase here, from 1 to 63 characters inclusive.
  • This is only used if you did NOT specify a hexadecimal key (see below,
  • for the _WIFI_PSK_HEX macro).
    */
    #define _WIFI_PSK_PASSPHRASE “put pass phase here”

/*

  • If you specify a hex key here, it is used instead of the passphrase
  • above. Hex keys should be exactly 64 hex digits long (i.e. 32 bytes).
    */
    // Following is valid for “now is the time” used with SSID=“parvati”
    #define _WIFI_PSK_HEX
    “7A3432A3F26912EFBE2B00DCE30CFA1CC5484F714EB85363580AA70FCA703780”

// Here is a simple key for testing
//#define _WIFI_PSK_HEX
// “1010101010101010101010101010101010101010101010101010101010101010”

// Of course, you do not have to hard-code keys as a string. You can
// also refer to a program variable as in the following…
//char my_psk[65];
//#define _WIFI_PSK_HEX my_psk

/*

  • Define this to print helpful messages when using WPA keys
    */
    #define WIFI_VERBOSE_PASSPHRASE

/** Remote interface to send PING to (passed to resolve()): */
/ Undefine to retrieve default gateway and ping that. */
#define PING_WHO “192.168.0.1”

/** How often to send PING’s (in milliseconds): **/
#define PING_DELAY 500

#define VERBOSE

/*

  • TCP/IP modification - reduce TCP socket buffer
  • size, to allow more connections. This can be increased,
  • with increased performance, if the number of sockets
  • are reduced. Note that this buffer size is split in
  • two for TCP sockets–1024 bytes for send and 1024 bytes
  • for receive.
    */
    #define TCP_BUF_SIZE 2048

/*

  • Web server configuration
    */

/*

  • Define the number of HTTP servers and socket buffers.
  • With tcp_reserveport(), fewer HTTP servers are needed.
    */
    #define HTTP_MAXSERVERS 2
    #define MAX_TCP_SOCKET_BUFFERS 2

/*

  • If you are behind a firewall, though, it might be a port on
  • the proxy, that will be forwarded to the Rabbit board. The
  • commented out line is an example of such a situation.

What you need to do, is to change the IP address in the samples to the IP address of YOUR local network. You need patience. :smiley:
