LWIP的NETCONN接口调用netconn_delete(udpconn)报错

yefeng159

  OS_EXIT_CRITICAL();                       
  data_len=0;                                 
   printf("%s\r\n",udp_demo_recvbuf);            
   netbuf_delete(recvbuf);                                                                                                           while(netconn_delete(udpconn) != ERR_OK);      


以下是提示的错误
Assertion "msg->conn->type == NETCONN_TCP" failed at line 1457 in LWIP\lwip-1.4.1\src\api\api_msg.c
Assertion "msg->conn->type == NETCONN_TCP" failed at line 839 in LWIP\lwip-1.4.1\src\api\api_msg.c
