Hi, Yukio Oyama-san,
Thanks for being interest in our products.
I apologize if this may cause any inconvenience for you.
We don't have these kind of products that can run ZigBee and Thread concurrently based on MPU(Linux OS) or without MCU. Only have products that can run ZigBee and Thread based on MCU as you know that, such as: K32W148,Rw612 and so on. For more details on each product, can visit our website.
For IW612, yes, we have plan to support ZigBee protocol, but we cannot engage on that yet, nor provide any ETA. Now IW612 only can support Thread protocol based 802.15.4.
So sorry about that.
Best regards,
Christine.
