Expected behavior

esp_mesh_lite_get_level should be return 1 or grater then 1

Actual behavior (suspected bug)

When the wifi mesh is networked, when the function esp_mesh_lite_get_level is called to obtain the level, 0 is returned. According to the code on GitHub, the function returns 1 to indicate that it is a router node. If the return value is greater than 1, it is a leaf node or an intermediate node. However, the return value is not defined as 0, and now 0 is returned, and the data is not processed, resulting in the module not being able to send the data to the route through the mesh.

Can you provide the log? esp_mesh_lite_get_level returns 0, which means WiFi is not connected properly.

there is no more log.this happen in the code "uint8_t layer = esp_mesh_lite_get_level();". If I execute the function "esp_restart" and then restart, it's still the same. If I reset via hardware, the function "esp_mesh_lite_get_level" returns 1 or greater than 1 and then it works.

The device is next to the router, and it doesn't feel like it's not connected to Wifi

Please update mesh lite to the latest version and try again.
