Re: MESH Broadcast Message

I have some tests on broadcast message, and the device could continues to receive messages after it was re-connected.
Would you please provide some logs here? I'm afraid I didn't get your point.

By the way, MESH_DATA_GROUP is not needed.

Re: Newbie Mesh

Any two nodes in mesh network could communicate using the shortest route.
Here's the brief of esp_mesh_send() #doc
Send a packet to any device in the mesh network.
Send a packet to external IP network.

Re: how the leaf node could send the data to other node around the whole mesh network

[quote="ESP_yudong"]How to get the address should be done in application.
Mesh network only charged with frames' transmission.

Re: Sending sensor data across mesh network

Either is OK.
MDF APIs are easier to use and IDF APIs are more flexible.

If the packet is to the root, set this parameter 'to' to NULL.

Re: How to connect to root node over wifi?

The internal_communication example didn't include http server or socket. You need to implement this function by yourself.

Re: invalid static ip

E (16366) event: invalid static ip

Don't worry about this line of logs.

Normally we don't need lwip or dhcp between mesh nodes, but tcpip_adapter_init() must be called before wifi start. So dhcp was stopped when mesh start. You can set a valid static ip if you really don't want to see this.

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

I am looking to create a multi-node mesh network that can interface with an android app
Only mesh devices can join mesh_ap,so there may be other difficulties when you try to do this.

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

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.
