About Objective System’s V2X API
The V2X API is available for C++, Java, and C#. It supports encoding/decoding V2X messages defined by SAE J2735 and ETSI standards.
The Python and Go wrappers enable easy conversion between binary and text encodings by providing a simple Python and Go interface on top of the C++ API.
