Issue or Suggestion Description

Hi all,

currently following the ESP_MESH_LITE_DEFAULT_INIT seen in the "mesh_local_control" example. I've 35 ESP32s, all on the same mesh ID and I can see that there is 3 master(root) nodes.

I've got my .max_router_number = 1 and yet I see this issue. they also do not have similar RSSI to the same AP. is there a threshold that is being missed for masters to be demoted to layer 2? if I lower the fusion threshold too much then it would cause instability with poor connection environments.

is the max_router_number used?

thanks in advance!! BR

The max_router_number is currently not being used.

You can try changing the fusion frequency to 20 seconds. If fusion still doesn't occur within a short time, please let us know.

esp_mesh_lite_fusion_config_t fusion_config = {
    .fusion_frequency_sec = 20,
};
esp_mesh_lite_set_fusion_config(&fusion_config);

Hi,

So by adding that above suggestion over the past 20 minutes and capturing the information from the system_info timer callback function into MQTT, the units are formed in the following way (see image below).

There are quite a number of master nodes and all are within a good range -35 > x > -54 dBm by my writing of this.

**EDIT: I've just checked back now at the 30 minute mark and I'm seeing now 4 masters and more substantial networks being formed

**EDIT-2: 1hr passed and the mesh is at 2 root nodes.

Thanks! BR

Hi,

I'm not sure when this appeared, however they are now all in one mesh unit (see below image)

I would probably attribute the speed in which the mesh is formed to being somewhat affected by the environment I'm testing them in.

Thanks as always
