V2X Smart Core is a V2X software stack delivered as a Software Development Kit (SDK) for various hardware platforms in transport, facilities and applications according to the customers' needs. The deliverables include SDK and the Ready-To-Use implementation of V2X applications for OBU and RSU.


A driver interface emulator "HMI" is available to demonstrate V2X Smart Core applications developed. The emulator is a mobile application for Android connected to an OBU device. According to scenarios, a driver gets messages. The interface example is shown below, where the built-in car screen via Android Auto displays the information.
HMI Emulator
Supported Platforms
NXP i.MX + Quectel AG15
Autotalks Craton 2
MuRata based on Craton 2 CUT 3
