调研方向
从链接的 micro-ros_reconnection_example.ino 开始，将其 rmw_uros_ping_agent、fini* 和重新初始化流程与相关的 issue 和 pull request 进行比较，尤其是 rmw_microxrcedds 的更改。明确 XRCE 定期重新通告或 agent-client 配置握手是否可行，然后定义双方认可的恢复行为及其验证用例。

https://github.com/micro-ROS/rmw_microxrcedds/pull/143/files
https://github.com/micro-ROS/micro_ros_arduino/issues/912
it appears the consensus is to use rmw_uros_ping_agent to detect the loss of agent communications, fini* and reinit all the bits, as exemplified here https://github.com/micro-ROS/micro_ros_arduino/blob/galactic/examples/micro-ros_reconnection_example/micro-ros_reconnection_example.ino
The communications with the agent is often over UDP, so its possible just to miss one of several init packets?
In this case the agent would be operating normally, and perhaps we wouldnt notice our missing service for a while.
Is it possible to periodically get the XRCE protocol to re-announce to the agent the set of nodes, topics etc, so that it would self recover?
Or is it feasible to implement some kind of "Tell me how you are configured, and I'll compare it to my idea of what I think you should be doing" handshaking in the protocol between agent and microros?
