How can I decrease WiFi MPU?
Posted: Tue Jul 26, 2022 4:14 pm
Hello,
our application is using MESH WIFI configured as in the example
https://github.com/espressif/esp-idf/tr ... al_network
We then do MQTT mTLS authentication from each node.
This generates a problem because the maximum size of MESH_MPS is 1472, while during the handshake a packet of 1494 is being sent by the server.
To trigger this error i think you can simply try to send a 1480 packet in the example above (from a leaf!)
Does anybody know how to reduce the MPU for the wifi/mtls/mqtt layer?
Thanks

Code: Select all
I (16:11:03.990) mesh_netif: Sending to node: 7c:df:a1:e0:69:a4, size: 1494
E (16:11:03.991) mesh_netif: Root: Send with err code 16392 ESP_ERR_MESH_ARGUMENT
