The firmware on the Nordic Thingy:53â„¢ is developed using the nRF Connect Software Development Kit (SDK).

The Edge Impulse firmware, which is preloaded onto the Nordic Thingy:53, enables the device to gather motion, sound, and environmental sensor data. The sensor data can be uploaded to the Edge Impulse Studio through the nRF Edge Impulse mobile application. In Edge Impulse Studio, the data can be used to train and test machine learning models that can be deployed to the Nordic Thingy:53 through Bluetooth® Low Energy.

For more information on the firmware and associated features, see Developing with Thingy:53 in nRF Connect SDK documentation.
