ISM43362 problem on B-L475E-IOT01A

First I initialize it

 if(ISM43362_Init() == WIFI_STATUS_OK)
 {
 USART_SendString(SYS_USART, "WIFI INIT OK\r");
 if(WIFI_GetMAC_Address(mac_addr) == WIFI_STATUS_OK)
 USART_SendString(SYS_USART, "MAC ADDRESS ");
 USART_SendHex(SYS_USART, mac_addr[0],0);
 USART_SendString(SYS_USART, ":");
 USART_SendHex(SYS_USART, mac_addr[1],0);
 USART_SendString(SYS_USART, ":");
 USART_SendHex(SYS_USART, mac_addr[2],0);
 USART_SendString(SYS_USART, ":");
 USART_SendHex(SYS_USART, mac_addr[3],0);
 USART_SendString(SYS_USART, ":");
 USART_SendHex(SYS_USART, mac_addr[4],0);
 USART_SendString(SYS_USART, ":");
 USART_SendHex(SYS_USART, mac_addr[5],1);
 }
 }
 else
 USART_SendString(SYS_USART, "WIFI INIT ERROR\r");

Got OK.

Then connect

 if( WIFI_Connect(SSID, PASSWORD, WIFI_ECN_WPA2_PSK) == WIFI_STATUS_OK)
 {
 if(WIFI_GetIP_Address(ip_addr) == WIFI_STATUS_OK)
 {
 USART_SendString(SYS_USART, "Connected: got IP Address ");
 }
 else
 {
	 USART_SendString(SYS_USART , "ERROR: CANNOT get IP address\r");
 }
 }
 

Got IP.

Now I start a server

if (WIFI_StartServer(SOCKET, WIFI_UDP_PROTOCOL, 1, "", PORT) == WIFI_STATUS_OK)
 USART_SendString(SYS_USART, "Start server - SUCCESS\r");
 else
 USART_SendString(SYS_USART, "Start server - ERROR\r");

Here I get - ES_WIFI_STATUS_UNEXPECTED_CLOSED_SOCKET.

What could be wrong?

Well...Seems like I can start a server only on WIFI_TCP_PROTOCOL. What if I want to configure a UDP server-client, how should I do it?
