WIFI Mesh connect parent on Root Node

[hben_pul]

Hi.
I develop WIFI Mesh project on ESP32.
On Root Node, I have some issue.

when I try to connect Router(External, For Sending Data to Server) using esp_mesh_set_parent function, if wifi config is invalid (like Wrong SSID Password), mesh repeat retry automatically internally. I fixed correct wifi config, and i call esp_mesh_set_parent for Router, the function is Fail(err is Internal State). I thought that internally retry continuous connect router, so the function is fail.
here is Question.
1. If the situation, If i want retry set parent, what do I need to call function?
Until Now, I found solution that Mesh stop, and ReStart, and then try to connect parent on correct config.

Thank you for help
