WIFI Mesh Internal communication fails with Guru mediation Error

Yuvaraj1867 · Postby **Yuvaraj1867** » Fri Feb 28, 2020 8:18 am

Hi,

I am working on WiFi Mesh where my task is to send temperature data from each child node to its parent node and that parent node will receive it and send it to other server via mqtt.
I am using ESP-IDF-V3.3's mesh->internal communication example as reference code.

I have written the code for it but it is just resetting with guru mediation error.
Here is my Log:

Rebooting...

As per EXCVADDR register address is close to zero. That means that application attempted to access member of a structure, but the pointer to the structure was NULL. But i am not able to solve the issue.

Kindly check and guide me.

I found.

Code: Select all

err = esp_mesh_recv(&route_table[i], &data, portMAX_DELAY, MESH_DATA_TODS, NULL, 0);

In this above line if i use "flag" as "MESH_DATA_TODS" , it is giving the above error log. If i use flag as "0", it is working.
As per programming guide we can use flag as below,

Code: Select all

    If the packet is to the root and “to” parameter is NULL, set this parameter to 0.
    If the packet is to an internal device, MESH_DATA_P2P should be set.
    If the packet is to the root (“to” parameter isn’t NULL) or to external IP network, MESH_DATA_TODS should be set.
    If the packet is from the root to an internal device, MESH_DATA_FROMDS should be set.

But i am not able to use MESH_DATA_TODS.

ChangMing · Postby **ChangMing** » Fri Mar 06, 2020 4:17 am

Code: [Select all] [Expand/Collapse]

esp_err_t esp_mesh_recv(mesh_addr_t *from, mesh_data_t *data, int timeout_ms, int *flag, mesh_opt_t opt[], int opt_count)

The type of flag parameter is int *, So a integer pointer should be pass to it.
After esp_mesh_recv() finished, the variable that the pointer linked to will be set MESH_DATA_TODS or MESH_DATA_FROMDS, according the direction of received packet(From DS/To DS).
