# Installing nRF Connect SDK (NCS) v3.2.1

![](https://3229153654-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MXjGw-Z8_tCuNQB93OW%2Fuploads%2FeiyF6cwEKDmbR4YoLC34%2Fnrfconnect.png?alt=media\&token=6c316a78-5d9d-46a6-8dce-a279ed7b5219)

The Conexio devices currently only support [<mark style="color:red;">ZephyrRTOS</mark>](https://www.zephyrproject.org/). To access all the features and capabilities, Nordic Semiconductor has developed the [<mark style="color:red;">nRF Connect SDK</mark>](https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/introduction.html) (NCS) which enables you to develop applications for nRF91 Series devices that power Conexio cellular devices.

{% hint style="info" %}
To support all the latest power and cellular features of the nRF91xx series SiP, Conexio Stratus device sample applications will only support nRF Connect SDK v3.2.1 or newer.
{% endhint %}
