Problem with UDPSocket and ticker.attach

Hi, i've a problem with UDPSocket class when I try to send a message inside a ticker.attach. In fact the board enters a sort of loop and does nothing; and so not send the message. Has someone a solution to this problem?

This is the code:

#include "mbed.h"
#include <stdio.h>
#include <string>
#include "EthernetInterface.h"

EthernetInterface eth;
UDPSocket sock;
Endpoint echo_server_pc;

void UdpSend(){ 
    //Read EthDevice
    char out_buffer[] = "Hello"; 
    sock.sendTo(echo_server_pc, out_buffer, sizeof(out_buffer));
};

int main (void)
{   
    eth.init("192.168.1.101","255.255.255.0","192.168.1.1"); //Not Use DHCP
    eth.connect();

    sock.init();
    sock.set_blocking(false);
    echo_server_pc.set_address("192.168.1.10", 8080);
    
    //Start the ticker
    tick.attach_us(&UdpSend, 100*1000);//100ms
    
    while(1){
         ....
    }
    ...
}

I've a K64F board. Thanks
