Expected behavior

we have a method 'esp_mesh_lite_get_nodes_list' to the current mesh node list but this list is updated in 'esp_mesh_lite.c' using the mutex node_info_mutex. But outside this we don't have a provision to access it. So during accessing the nodes retuned by 'esp_mesh_lite_get_nodes_list' method, the node list might get updated (added/deleted) and causing the crash while accessing it. Is there any way to copy the node list or access the nodelist with thread safe. I use the CONFIG_MESH_LITE_REPORT_INTERVAL as 5 secs

Actual behavior (suspected bug)

I don't see any option to access the nodelist returned by esp_mesh_lite_get_nodes_list() threadsafe.

Error logs or terminal output

Steps to reproduce the behavior

Enable esp mesh lite and change the CONFIG_MESH_LITE_REPORT_INTERVAL value to 5 (from default 300). Print the nodelist details from the object returned by esp_mesh_lite_get_nodes_list() Crash happens while accessing the mac address of one of the nodes from the node list.

Under normal circumstances, for safety reasons, the esp_mesh_lite_get_nodes_list API should return a copy rather than the original variable.

In the release/v1.0 version, this part of the operation is not fully implemented. You can manually modify the logic in mesh_lite/src/esp_mesh_lite.c.
