本文描述了使用simple_udp_sendto进行节点间通信时遇到的问题。当通过UDP发送大型ELF模块文件（约1-2KB）时，文件被分为大约30-40个64B的数据块。一段时间后出现tcpip_ipv6_output找不到路由错误，导致通信在单向中断。服务器节点仍能接收来自客户端请求数据块的消息，但无法反向通信。

I'm using simple_udp_sendto to communicate between nodes. A border
router was initialized with a prefix to start the RPL mesh netwrok.

I'm sending large files (ELF modules, 1~2 KB length) divided in chunks
(about 30 - 40 chunks of 64B each) using this function, however, some
time after I got this error:

tcpip_ipv6_output: no route found, using default route

And then communication between nodes is broken in only one direction.

The "server" node can receive messages from the "client" asking for
chunks, but not in the other way.
