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) that enables you to develop applications for nRF53, and nRF91 Series devices that powers Conexio devices.

To make nRF Connect SDK installation a breeze, follow the following steps.

* Download and install a cross-platform tool [<mark style="color:red;">nRF Connect for Desktop</mark>](https://www.nordicsemi.com/Products/Development-tools/nrf-connect-for-desktop) for your operating system.
* Install and run the nRF Connect tool on your machine.
* Click I**nstall** next to the Toolchain manager as shown below.

The Conexio BLITZ sample applications are currently compatible with **nRF Connect SDK V2.6.0 and above.**&#x20;
{% endhint %}

* Select **nRF Connect SDK v2.6.0** and click **Install**. Depending on your internet speed, it may take a few tens of minutes, so go and grab yourself a cup of coffee **☕**
