is it possible to send big array over UDP?

Question

i want to send large array (array[1600]) with stm32f767 and lan8720a with udp. when my array biger than 1319 byte the mcu can not send(i don't receive anything with my terminal software(UdpClientServer.exe) ) my array is full of 'A' character

'''

void MY_UdpSendData(void) {

uint16_t i=0;
uint16_t BufferSize=0;

struct pbuf *p;

while(array[i]=='A')
{
    i++;
    BufferSize++;
}

p = pbuf_alloc(PBUF_TRANSPORT, BufferSize, PBUF_RAM); 
 pbuf_take(p, array, sizeof(array[0])*BufferSize);

udp_send(udp_send_pcb, p);

pbuf_free(p);

}

//////////while(1)

while (1) {

    MX_LWIP_Process();
    
    cntr++;
    if(cntr > 200000)
    {
        cntr=0;
        MY_UdpSendData();
        
    }

}
