Designation of the route with OpenThread

[inari]

Hi, I tested "Simple_coap_client" and "simple_coap_server" on NRF52840 using Threading SDK.

It seems that the route is decided by the leader, can I specify the route?

If possible, we believe that dispersing the routes may improve performance.

I'm sorry in poor English.

Hi,

The Thread protocol uses a proactive, shortest-path, any-to-any, distance-vector routing protocol. In a Thread Network, all Routers periodically exchange single-hop MLE advertisement packets containing link cost information to all neighbor Routers, and path costs to all other Routers in the Thread Network.

As far as I know, there is no way to specify the route manually.

For more details, I would recommend you to read the Thread specifications, and/or the Thread Overview white paper.

Best regards,
Jørgen

The MLE packets are handled by the OpenThread stack. The OpenThread stack is provided as linkable libraries in the SDK. You can build the stack on your own PC in order to debug and step through the sources.
