Software

Featuring with V2Xcast® , Unex’s innovative software technology, EVK-301E allows two modes of operation:

1. Hostless Mode: EVK works as a standalone full-featured V2X unit

EVK works as a standalone full-featured V2X unit

2. Hosted Mode: EVK works as a V2X communication unit to existing application host

EVK works as a V2X communication unit to existing application host

Unex EVK-301E enables ease of V2X software development through its V2Xcast® technology. Previously, V2X protocol software had to be built and verified complicated APIs, resulting in a duplicated effort, risk and cost. With Unex V2Xcast solution that provides ready-to-use V2X communication services for V2X applications, users can significantly cut time-to-market with less development and testing cost.

V2Xcast is supported in EVK-301E to facilitate V2X application development through its modular framework. It includes two parts – V2Xcast Service and V2Xcast SDK.

V2Xcast SDK

Deploy V2Xcast SDK in either EVK-301E or external application host, it includes APIs to get the services from V2Xcast Service and the main functions of facility layer (ITS-MSG), such as message encoder/decoder and example code.

V2Xcast Service

V2Xcast Service image resides in EVK-301E, it combines ETSI ITS-G5 protocol stack that includes GeoNetwork, BTP, DCC, Security, and POTI. V2X communication protocols will be easily enabled via configuration input without any programming.
