I am wondering if it's possible to use ethernet and the best way to achieve this.
I have an esp32 dev board with an ethernet port and I currently have ethernet connecting and getting an ip, with the mesh set up as being a root node, as in routerless example. The code is mostly the same as the mwifi mqtt_example but with addition of ethernet code.
The problem is that MDF_EVENT_MWIFI_ROOT_GOT_IP event never happens so the code that sets up mqtt, root tasks, etc. doesn't get called, see https://github.com/espressif/esp-mdf/bl ... ple.c#L338
I tried esp_mesh_post_toDS_state(true) after getting an ip address from ethernet but it doesn't work.
I also tried sending the event myself e.g. mdf_event_loop_send(MDF_EVENT_MWIFI_ROOT_GOT_IP, NULL) which works but later code such as esp_mesh_get_routing_table() returns nothing because it hasn't registered the root node over ethernet.
Perhaps I just need to rewrite this part of the code but is what I'm doing sensible? I suspect even if I got this working other things like mupgrade wouldn't work. I was looking at the eth2ap ethernet example and wondered if I could do the same thing, redirect ethernet to ap so the mesh thinks it's connected to a router and I don't have to change any code.

Re: Using ethernet instead of wifi at root node
Your plan is OK, there are other customers who use it as well.
1. You can add it based on the simple example of get-started
Ethernet function
2. You need to add your mqtt creation in got_ip_event_handler
3. If you still can't solve it, please provide us with your code example. We can help you analyze the problem.

Re: Using ethernet instead of wifi at root node
Hi,
I'm interested to get the same thing ( esp-mesh <----> ethernet or cellular).
Unfortunately i don't know where to start.
Can't you help me giving some links or ideas ?
Best regards.

Re: Using ethernet instead of wifi at root node
I think you would take the no_router example as a starting point:
https://github.com/espressif/esp-mdf/tr ... /no_router
Then instead of communicating over UART on the root node, you'd communicate over Ethernet/MQTT/Whatever.
