Qualcomm Telematics SDK Application Notes

C-V2X occasionally needs secure TCP/IPv6 sessions between a vehicle’s onboard unit (OBU) and Internet application servers. For example, C-V2X-equipped vehicles can receive IEEE 1609.2 certificate top-offs, certificate revocation lists (CRLs) or report misbehavior. This is often done over cellular networks, but sessions can also be established through an Internet-connected roadside unit (RSU). Where available, RSU connections reduce traffic volumes sent via cellular networks. This documentation and open source sample code illustrates how road operators and C-V2X device manufacturers can achieve this connection with existing devices that have only link-local addressing.
