子节点每隔20秒发送一包给父接点，父节点再发回应答包，一段时间后，发现日志报ESP_ERR_MESH_NO_MEMORY，是不是底层mesh发送不成功，没扔掉缓存数据？

这边有乐鑫技术支持吗？有问题如何对接呢？这个多次发送时底层mesh超时自发，如何改底层这部分呢？

放弃吧

@yeqinggui 这个是因为节点前面一直发送不出去数据，可以看到 <ESP_ERR_MESH_TIMEOUT> Node failed to send packets，这个log。然后一直还在不停的发送，从而导致底层 mesh buffer满了，从而后面才打印了 <ESP_ERR_MESH_NO_MEMORY> 。所以需要先解决为什么前面发送不成功原因。

发送不出数据应该是通信连接问题吧，那么这种通信异常，底层为何不扔掉数据？

@Jiangyafeng

是因为你的应用层一直调用 esp_mesh_send 发送，节点又发送不出去从而导致的。这个时候你应该做一个判断，从而停止应用层的发送，等待消息不阻塞，能够通讯成功之后，再去发送数据。

有做mwifi_is_connected()判断，ture 才发送，那么若是这个判断无效，要通过写mwifi_write写后返回才知道异常，那如何避免一直写？最终还不如底层没做这个限制？

今天也碰到了，就是前面出现10几次ESP_ERR_MESH_TIMEOUT后，就会出现ESP_ERR_MESH_NO_MEMORY，此时并没收到ESP_MESH_CHILD_DISCONNECTED消息，链接并没断开，只是发不出去
