# Device SDK

Since KPN Things is a data platform, it prescribes with which data format your Device should communicate with KPN Things. The KPN Things Device SDK helps you to quickly connect your Device to KPN Things.

You can find the Device SDK library on Github: <https://kpn-iot.github.io/thingsml-c-library/>

The Device SDK is mainly based on the [ThingsML](https://docs.kpnthings.com/kpn-things/building-blocks/data-processing/thingsml-and-senml/thingsml) data format. ThingsML is an extension of SenML created by KPN. For SenML we have also developed a library which is available for C, Python, and MicroPython. Visit the [SenML library documentation](https://kpn-iot.github.io/senml-library/).

The Device SDK is available in the following languages:

* [Things Device SDK in C++](https://github.com/kpn-iot/thingsml-c-library)
* [Things Device SDK in Python](https://github.com/kpn-iot/senml-python-library)
* [Things Device SDK in MicroPython](https://github.com/kpn-iot/senml-micropython-library)
