3.13.4 When using
mdf/examples/function_demo/mwifi/router example, After ESP32 is connected to
the router, the device name in connection is "espressif". How to modify this
name?
• Please modify the "menuconfig → Component config → LWIP → (espressif) Local netif hostname"setting.

3.13.5 Can Wi-Fi Mesh send messages to specific nodes via TCP Server?

• Wi-Fi Mesh network can send data to the specified node or group in the TCP server, please refer to the demo.
3.13.6 During the operation of the ESP32 Wi-Fi Mesh network, if the Root node is lost,
what events will the system report back?
• If the Root node is lost, all nodes will trigger 'MDF_EVENT_MWIFI_PARENT_DISCONNECTED
(MESH_EVENT_PARENT_DISCONNECTED)' , and then start rescanning and re-election until a new Root
node is elected.
3.13.7 I' m using ESP32 for Wi-Fi Mesh application with the esp_mesh_send() func-
tion, but the server did not receive any data. How to transfer data from leaf nodes
to external servers?
• esp_mesh_send() can only be used for data communication within the Wi-Fi Mesh network.
• If leaf nodes want to send data to an external server, the data needs to be forwarded through the root node.
• The correct approach is: the leaf node first sends the data to the root node, and the root node then sends the
data to the external server.

3.13.8 How do I upgrade my ESP-MESH device via OTA after networking?

• The ROOT node can connect to the server to get the upgrade bin file and then send the firmware to the corre-
sponding module via MAC address for OTA upgrade.

3.13.9 Can you provide ESP-MESH light reference design?

• The overall design of the lamp is done by a third-party factory and we do not have a schematic or PCB layout.
But from the module level, we only need to supply power to the chip and the chip outputs PWM to control the
color or color temperature change of the lamp, which does not involve complicated design.
