HTTP Client doesn't connect to websites
PostPosted: Sat Mar 21, 2020 6:24 am     Reply with quote

Hi,

I have a problem with HTTP Client. It can connect local IP addresses but not internet hosts or internet IPs with and without custom headers. I have tried many website and IP address.

I think HttpClientSetHostNameROM can't resolve DNS. Both SNTP and CCS SNTP doesn't get the epoch also.

Could you help me what is wrong?

Look at the driver dns.c and the example ex_dnslookup.c
Understand the TCPIP driver, does not itself automatically perform DNS
lookup.

Finally I have solved the problem. Wink I have added theese lines the end of IPAddressInit function:

Code:

AppConfig.PrimaryDNSServer = AppConfig.MyGateway.Val;
AppConfig.SecondaryDNSServer.Val = 0;


IPAddressInit
Code:
void IPAddressInit(void)
{
    //AppConfig.Flags.bIsDHCPEnabled = 0;
    //DHCPEnable(0);
   
   //MAC address of this unit
   MY_MAC_BYTE1=MY_DEFAULT_MAC_BYTE1;
   MY_MAC_BYTE2=MY_DEFAULT_MAC_BYTE2;
   MY_MAC_BYTE3=MY_DEFAULT_MAC_BYTE3;
   MY_MAC_BYTE4=MY_DEFAULT_MAC_BYTE4;
   MY_MAC_BYTE5=MY_DEFAULT_MAC_BYTE5;
   MY_MAC_BYTE6=MY_DEFAULT_MAC_BYTE6;

   //IP address of this unit
   MY_IP_BYTE1=MY_DEFAULT_IP_ADDR_BYTE1;
   MY_IP_BYTE2=MY_DEFAULT_IP_ADDR_BYTE2;
   MY_IP_BYTE3=MY_DEFAULT_IP_ADDR_BYTE3;
   MY_IP_BYTE4=MY_DEFAULT_IP_ADDR_BYTE4;

   //network gateway
   MY_GATE_BYTE1=MY_DEFAULT_GATE_BYTE1;
   MY_GATE_BYTE2=MY_DEFAULT_GATE_BYTE2;
   MY_GATE_BYTE3=MY_DEFAULT_GATE_BYTE3;
   MY_GATE_BYTE4=MY_DEFAULT_GATE_BYTE4;
   
   //subnet mask
   MY_MASK_BYTE1=MY_DEFAULT_MASK_BYTE1;
   MY_MASK_BYTE2=MY_DEFAULT_MASK_BYTE2;
   MY_MASK_BYTE3=MY_DEFAULT_MASK_BYTE3;
   MY_MASK_BYTE4=MY_DEFAULT_MASK_BYTE4;
   
    AppConfig.PrimaryDNSServer = AppConfig.MyGateway.Val;
    AppConfig.SecondaryDNSServer.Val = 0;
}
