NDK: DHCP - Ip.autoIp = true;

Hi Soumyajit,

You can do this at run time.  You must use the NDK's C runtime configuration APIs (discussed in detail in the NDK API guide, Appendix G "Legacy Configuration Manager API"), such as CfgAddEntry, etc.

You can use a "cheat" to get this code from your application.  First, build your app with DHCP client configured.  Then look at the generated C file (e.g. in your project's sub folder Debug\configPkg\package\cfg\<project name>_pem4f.c).  Then in the function "ti_ndk_config_ip_init" you can find the C code to configure your app to be a DHCP client.

Change the configuration for a static IP, rebuild.  Again, look at the ti_ndk_config_ip_init function and this time you will see the settings for a static IP.

Please also refer to this related thread which has more info on this.

Hi Steven,
Thanks for the reply. I have earlier successfully implemented IP address changing during run time & it worked. But am unable to figure out how the DHCP can be enabled or disabled!! I have gone through the NDK API Guide also but it seems not that helpful in this matter.
I am providing below the function that is currently in my code (being triggered by the Network Open Hook) related to changing the IP address. Would you mind adding a few lines of code to it showing the DHCP enabling & disabling? Thanks for your help.

Void functionNetworkOpenHook(Void)
{
CI_IPNET NA;

HANDLE hCfgIpAddr;

/* Setup manual IP address */
bzero(&NA, sizeof(NA));
NA.IPAddr = inet_addr("192.168.1.2");
NA.IPMask = inet_addr("255.255.255.0");
strcpy(NA.Domain, "demo.net");
NA.NetType = 0;

/* get the current static IP entry */
CfgGetEntry(0, CFGTAG_IPNET, 1, 1, &hCfgIpAddr);

/* remove the current static IP entry */
CfgRemoveEntry(0, hCfgIpAddr);

/* add a new static IP entry */
CfgAddEntry(0, CFGTAG_IPNET, 1, 0,
sizeof(CI_IPNET), (UINT8 *)&NA, 0);
}

Hi Steven,

 Thanks for putting in your valuable time for my queries. I found out this code file on google & I think it clearly indicates the enabling & disabling of DCHP. Will try out the code parts very soon!!
