Hi there, I have a question. Can I remove device os from particle device and use pure nrf52480? ---

You can, but why would you want to? 😉 ---

I want to create mesh without gateway. (I want to paired mesh devices without Internet, I think use OpenThread directly). May be you have some thoughts about it? ---

If you have some idea how I can use nrf chip directly, can you share it:) ---

Nope, I’ve no deeper insight into that, but you’d have to start with getting yourself acquainted with the Nordic SDK and the OpenThread implementations for it. ---

> [@kmakhno](#): > > I want to paired mesh devices without Interne Why not use them as they are but disable the cloud connectivity? This is were I would go if I were you. However, I'm not 100% sure this is possible, but for me it would be worth trying before getting into the pain of flashing a new OS to the device. Cheers Gustavo. ---

Ok, I try it, but what does it mean: “The device will be registered in the network once it is connected to the cloud.”? I don’t understand, I need anyway cloud connection to registered my network? It’s some strange. Ok, without internet I create mesh network on Argon, and it was successfully, but when I try add node(Xenon) to my network I catch this error: “The assisting device is not a member of any mesh network”. I did it by this guide [https://docs.particle.io/support/particle-devices-faq/mesh-setup-over-usb/#gateway-setup](https://docs.particle.io/support/particle-devices-faq/mesh-setup-over-usb/#gateway-setup). Thanks a lot. ---
