Re: UDP Client Problem

hi
I know the port of my server an i am sending data successfully.
But my microcontroller (server using some other library to send and
receive), microcontroller wants to know the port an ip of remote host (means
client), this means i have to bind my client (in UDP) so that microcontroller
can send data to client.
Actually i am sending request from client (PC) to Server (Microcontroller)
and in return micocontroller is sending the required data to me.

Thanks for help in advance.
Bye

No, client have to know server's port and send to data to it, OTOH server
can check that when recvfrom() returned successfully

No, you don't need to bind client client both in UDP and TCP

Hi
I have to made a UDP client.
Do i ned to bind it or not.

My Server has following function for dending data to client
----------------------------
int NutUdpReceiveFrom ( UDPSOCKET * sock,
u_long * addr,
u_short * port,
void * data,
u_short size,
u_long timeout
)

Receive a UDP datagram.


Parameters:
sock Socket descriptor. This pointer must have been retrieved by
calling
NutUdpCreateSocket().
addr - IP address of the remote host in network byte order.
port - Remote port number in host byte order.
data - Pointer to the buffer that receives the data.
size - Size of the buffer that receives the data.
timeout - Maximum number of milliseconds to wait.

-------------------
But problem is its asking for the remote host IP Address and Port.
This menas i have to bind my client to specific port.
Am i right?

Thanks for help in advance
BYe
