Does OpenThread support dual interfaces, Thread and Ethernet?

[jinpeng1989]

We want to develop a product based on CoAP. Its CoAP resources support access from both Ethernet and Thread networks. Does the OpenThread stack support dual interfaces? Which chip can implement this solution?

[jinpeng1989]

Both single-chip and multi-chip solutions are available.

OpenThread currently does not support multiple interfaces on its own. Existing implementations typically involve integrating OpenThread as a network interface into another network stack (e.g. Linux network stack, Zephyr network stack, LwIP, etc.).

In the NCP solution, the Host Processor and 802.15.4 SoC communicate over the Spinel protocol. If the operating system of the Host processor is free-RTOS, and the Third-Party IPv6 stack is lwip, what components should be used to implement Spinel of Host processor?

[jwhui]

Currently, the OpenThread project itself does not include any integration with FreeRTOS + LwIP host. That said, I know that implementations exist, such as with Espressif.

Thank you.
What Spinel commands do Host Processor and NCP use to exchange IP packets? For example, sniffing raw packets are passed by NCP to Host via CMD_VALUE_IS: PROP_STREAM_RAW: .... Can you point it out for me?

Check these two:

• SPINEL_PROP_STREAM_NET and
• SPINEL_PROP_STREAM_NET_INSECURE

Thank you.
