Hi All,
I am trying to change the IP address from static to dynamic and vice versa in runtime. All the drivers and wifi has been initialized previously and is working fine. Later at some time, I need to switch from dynamic IP to static IP and again from static to dynamic. This is my function which is performing this-
sl_NetCfgGet(SL_IPV4_STA_P2P_CL_GET_INFO, &dhcpIsOn, &len, (unsigned char *) &ipV4);
///////////////// getting reset here
I am getting reset here. WHy is it so?
Thanks
bool reconnectWifi(char* ipAddr, char* ipMask) //
{
if (strlen(ipAddr) < 7 || strlen(ipMask) < 7)
{
return false;
}
g_lastWiFiSwitchSecs = Seconds_get();
sl_WlanDisconnect();
sl_Stop(800);
g_lastWiFiSwitchSecs = 0;
SlNetCfgIpV4Args_t ipV4;
uint8_t len = sizeof(ipV4);

0);
