Hi all,
I'm using K60 (tower board) and MQX 3.7
I'd like to use socket to receive UDP packets (800bytes every 32ms) in 2 different ports.
I have tried to use RTCS_selectall but I lose some packets.
So I'have tried this simple code:
....
_int_install_unexpected_isr();
// Inizialize networking
initialize_networking();
// local address initialization
laddr.sin_family = AF_INET;
laddr.sin_port = 2500;
laddr.sin_addr.s_addr = INADDR_ANY;
// Create a datagram socket:
socklist[ID_SOCKET_SDO] = socket(PF_INET, SOCK_DGRAM, 0);
if (socklist[ID_SOCKET_SDO] == RTCS_SOCKET_ERROR) {
printf("\nFailed to create datagram socket.");
_task_block();
}
// Bind the datagram socket to the UDP port:
error = bind(socklist[ID_SOCKET_SDO], &laddr, sizeof(laddr));
if (error != RTCS_OK) {
printf("\nFailed to bind datagram - 0x%lx.", error);
_task_block();
}
laddr.sin_port = 2501;
// Create a datagram socket:
socklist[ID_SOCKET_PROFILO_MOTO] = socket(PF_INET, SOCK_DGRAM, 0);
if (socklist[ID_SOCKET_PROFILO_MOTO] == RTCS_SOCKET_ERROR) {
printf("\nFailed to create datagram socket.");
_task_block();
}
// Bind the datagram socket to the UDP port:
error = bind(socklist[ID_SOCKET_PROFILO_MOTO], &laddr, sizeof(laddr));
if (error != RTCS_OK) {
printf("\nFailed to bind datagram - 0x%lx.", error);
_task_block();
}
// Echo server
// error = ECHOSRV_init("EchoServer", 17, 1000);
// if (error != RTCS_OK) {
// printf("\nFailed to echo server init - 0x%lx.", error);
// _task_block();
// }
while (TRUE) {
// prepare recevive structs
GPIOA_PDOR ^= BIT_29; // green led TOGGLE
sock = RTCS_selectset(socklist, NUM_SOCKET_WAITING, 100);
...
}
If I stop the sender device, I suppose I have to see every 100ms my led toggle.
This doesn't happen, the timeout is... random. Sometimes is bigger than a second.
Why?
Thank you
G
