It is possible to communicate via the UART interface with the NB|DevKit and send user data to the cloud.
Therefore the jumper on the development board needs to be changed as mentioned in the hardware guide. The USB cable is still needed for providing power to the DevKit.
This application note uses an Arduino, but any other device with a UART interface (for example a Raspberry PI) can be used to communicate with the device. Only the logic voltage level has to be adjusted to 3.3 Volts.
