Frequently Asked Questions
The Definition of the Vodafone NB-IoT Development Kit: The Vodafone NB-IoT Development Kit consists of an NB-IoT modem board (EX-COM 210) operating in Band 8 & 20, a connector board offering UART, RS232 & USB connectors, a software tool (NB|EASY Software) and a IoT-Cloud (IoT-Manger). The Vodafone NB-IoT Development Kit was designed to simplify NB-IoT development. The user can get first experience with the NB-IoT standard by simply transmitting a "Hello World" string in the IoT cloud within minutes. Beside the transmitted string, the development kit also transmits UE statistics into the cloud using the NB-IoT Network of Vodafone. This data can be viewed there (alike the sensor data that is transmitted via the modem) and give you a good insight into the connectivity performance of the NB-IoT device. Development KIT. This end-to-end transmission can be a starting point for further development.
You can order the Development Kit from the Vodafone Website.

There are two ways to communicate with a different backend than the Vodafone backend
via UDP
NB-IoT devices support primarily only the UDP-protocol. You can not use TCP or higher protocols based on TCP. The backend/cloud, you want to communicate to, must support an UDP-endpoint. You can either change the backend IP via the NB | EASY tool or when you are using the NB | Easy interface.

- NB | EASY Interface - section Transmission
via Protocol Proxy
There are existing software components, which connect NB-IoT devices to a backend via a proxy, which provides other protocols like HTTP or MQTT. If you are interested in this solution, contact the team of exelonix GmbH.
