Can we fake esp-mdf root to avoid using a router yet?

Postby jeffdc1979 » Tue Sep 25, 2018 2:47 pm

I am looking to create a multi-node mesh network that can interface with an android app only and not require the need of a router and IP address. I am hoping to be able to send data directly from the android device to the closest node in the mesh network that can act like a parent or root node to avoid having to run the data through a router ... essentially acting as a gateway to the mesh network. I have read all the other forum posts requesting this functionality and I see that it is "planned" but what is the status of it and is there a way to "hack" the code to allow for this or is it not open-source enough to allow?

I'm newbie to esp32, but what you want is teoritically possible if (1) you could have low level access to android wifi interface and (2) you mimic esp-mesh protocol.

I don't think (1) is possible and (2) seems to be undocumented

We could set a node as root manually using esp_mesh_set_type() or esp_mesh_set_parent() in the lastest esp-idf version. Then mesh network can be established without router.

Only mesh devices can join mesh_ap,so there may be other difficulties when you try to do this.

Isn't there android code to interface with the mesh network??? I am confused why you don't think this is possible or difficult?

I want to do something simmilar: I need a mesh network to exist in a location without a router. Worst case is we could use another ESP32 as an AP and have the mesh self-organize around an ESP32 AP, right?

I'm about to give this a try.
