How often does this bug occurs?

always

Expected behavior

Node stays as an idle node

Actual behavior (suspected bug)

Node becomes a root node

Error logs or terminal output

Steps to reproduce the behavior

Setup ESP-IDF v5.4
Download Mesh Local Control example
Set ssid to hidden (I unfortunately haven't tested without it so I can't say whether that's relevant or not)
Between the init and the start of mesh lite, call esp_mesh_lite_set_disallowed_level(1) or esp_mesh_lite_set_router_min_rssi_threshold(0) (I've tried both)
Program a ESP32-S3 dev board with the example, and run it.

May I ask which version you are using? On my end, I cannot reproduce the issue with either the ​master branch or ​version 1.0.1. When the device calls esp_mesh_lite_set_disallowed_level(1), It will not attempt to connect to the router.

I'm using version 1.0.1.
Did you have the ssid set to hidden like in my setup? That's the only difference I made compared to the supplied Mesh Local Control example

I couldn't replicate the problem on my end. Would you mind sharing your code and the full logs for further investigation?

@Aric5301

Would the situation change if you changed the hidden SSID to a normal SSID?

In ESP-MESH-LITE, the root node is determined by the following rules:

ESP-MESH-LITE: By default, the device that is powered up first after provisioning is selected as the root node. 
If more than one device are powered up at the same time, after all devices are connected to the router, all devices start to broadcast the router RSSI, and the one with the strongest RSSI is selected as the root node. 
The rest of the nodes disconnect from the router and re-scanning for the new parent node.

I quoted it from here.
