UDP Socket Issue

Hello,

I am having a problem with the UDP Socket object. I am using an EA-LPC4088. Below is some example code where I am expecting the receiveFrom() method to timeout after 1000msec. However, it never times out if there is no packet traffic. Am I doing something wrong or is there an issue with the EthernetInterface class?

Regards,

Tom Doyle

Include EthernetInterface and mbed-rtos libs with with example

include "EthernetInterface.h"

DigitalOut myled(LED1, 1);
EthernetInterface gEth;
UDPSocket gSocket;

int main() {
    printf ("Starting Program\r\n");
    
    if (gEth.init("195.0.0.6", "255.255.255.0", "195.0.0.1") < 0)
    {
        error("FATAL Error: Ethernet Initialization Error\r\n");
    }

    if (gEth.connect(10000) < 0)
    {
        error("FATAL Error: Ethernet Connection Error\r\n");
    }
    
    if (gSocket.bind(4323))
    {
        error("FATAL Error: Unable to bind ALXT_MSG_PORT socket");
    }
    
    gSocket.set_broadcasting(true);
    //gSocket.set_blocking(true, 1000);
    
    Endpoint source;
    char receiveBuf[512];
    
    while(1) 
    {
        gSocket.receiveFrom(source, (char*)receiveBuf, sizeof(receiveBuf));
        myled = !myled.read();
    }
}
