Freertos based application is taking too long to get started
I have a FreeRTOS application which
opens a UDP socket and transmit packets and receive response.I have used socket.c and W5100.c iomedia library files to build this application with WHiznet EThernet shield. Now When i put a task delay between startup and UDP socket transmitting first packet my application works fine, But if i remove this task delay then no packet is received at Server end. However sendto still returns correct length of packet transmitted.Can somebody please suggest some way how i can debug the application.
void vTaskCode( void * pvParameters )
{
/* The parameter value is expected to be 1 as 1 is passed in the
pvParameters value in the call to xTaskCreate() below.*/
configASSERT( ( ( uint32_t ) pvParameters ) == 1 );
vTaskDelay(20000/portTICK_PERIOD_MS); ***// If I remove this delay packet will never reach other machine.***
socket(DHCP_SOCKET, Sn_MR_UDP, DHCP_CLIENT_PORT, 0x00);
**// create the DHCP message here.**
sendto(DHCP_SOCKET, (uint8_t *)pDHCPMSG, RIP_MSG_SIZE, ip, DHCP_SERVER_PORT);
}

I think first of all you need 2 different tasks for transmiting and receiving.
Sometimes delay is neccessary for tasks synchronzation.
Could you share a part of code?

Well The problem is not with rx side as once 1st packet is successfully transmitted , than flow works fine and i can send any number of packets after this. But I have to introduce a 20 seconds delay after application init and before transmitting else my socket won't transmit packet eventhough sendto doesn't returns error.
