When using espressif‘s esp mesh, although it has a function of

esp_mesh_fix_root

but it still can't be used away from the router. Because in the function

esp_mesh_set_parent

, the parent configuration, the ssid and the channel of the parent are mandatory. Therefore, in the case of leaving the router, it will trigger the

Code: Select all

MESH_EVENT_PARENT_DISCONNECTED

event.
But in fact, the mesh network itself can still communicate normally.

Because the root is fixed，So I think the parent of the root is preferably optional. If you offer such a choice, we can build a network system that does not require router. It can extend the application scenario of esp mesh .I really hope to get your official reply.

Moved to MDF, as it's more relevant there,

Thanks for your suggestions.
And we also have the plan to support non-router network in the near future. Then you could build a network like you said.

More Suggestions are welcome.

Do you have an expected release plan?
Now I am dealing with this,

Set a parent node that does not exist.

Code: Select all

void wifi_mesh_set_root_parent(void)
{
  wifi_config_t parent =
  {
    .sta =
    {
      .ssid = CONFIG_MESH_ROUTER_SSID,
      .password = CONFIG_MESH_ROUTER_PASSWD,
      .channel = CONFIG_MESH_CHANNEL,
    },
  };
  ESP_ERROR_CHECK(esp_wifi_scan_stop());
  wifi_scan_config_t scan_config = { 0 };
  scan_config.show_hidden = 1;
  ESP_ERROR_CHECK(esp_wifi_scan_start(&scan_config, 0));
  ESP_ERROR_CHECK(esp_mesh_set_parent(&parent, &mesh_configuration.mesh_id, MESH_ROOT, 1));

and then if event MESH_EVENT_PARENT_DISCONNECTED triggered，still call esp_mesh_comm_p2p_start directly.

Code: Select all

    case MESH_EVENT_PARENT_DISCONNECTED:
      mesh_layer = esp_mesh_get_layer();
      if (esp_mesh_is_root())
      {
        //tcpip_adapter_dhcpc_stop(TCPIP_ADAPTER_IF_STA);
        tcpip_adapter_dhcpc_start(TCPIP_ADAPTER_IF_STA);
      }
      esp_mesh_comm_p2p_start();
