Hi all

I have an issue where some nodes don't come online at all, possibly restarting the ESP32's they may come online. I have seen no pattern to this, some are fine, some aren't, some may come up during one test and then refuse to connect at all.

I also have an issue where they may just drop out of the mesh completely, they don't seem to reconfigure themselves to get connected back up. Again, I can find no pattern to this. It doesn't seem to be signal strength related.

I am testing with around 20 nodes, they are spaced out evenly.

Mesh config posted below:

Code: Select all

    esp_mesh_lite_config_t mesh_lite_config = ESP_MESH_LITE_DEFAULT_INIT();
    mesh_lite_config.join_mesh_ignore_router_status = true;
    mesh_lite_config.join_mesh_without_configured_wifi = true;

Please let me know if you require anything else.

Thanks
Martin

The official samples are published here.

Which sample code are you using?

I have used both the example code from the Espressif Github page you linked and your examples nopnop from your Github account.

Below is an example of my most seen error

I can't figure out how other people are using the example code and having stable results when I can not

Try clearing the flash once.

@mhISTL

I am having the same issues and the results are unpredictable for me.
It keeps trying to connect even if the nodes are within the range of each other.

Were you able to resolve this?
