COVESA has a liaison agreement with e-Sync Alliance to explore common interests.

e-Sync Alliance is an initiative to define Over The Air updates (OTA/SOTA) and Disgnostics.

A presentation LINK PENDING of the activities was made at the Automotive Linux Summit in Tokyo, December 2021.


Background

e-Sync is interested in leveraging the use of their OTA protocol not only for software transfer (cloud to vehicle) but also data transfer (primarily vehicle to cloud). 
It was early on decided that the work within CVII to achieve an automotive industry-common data model, and use of VSS in particular, was desirable for such work.

Protocol Specification

e-Sync develops and publishes OTA protocol specifications among their members. 

Message Formats

Some of e-Sync technology leverages the AVRO methods of encoding

Therefore a specification and implementation of AVRO encoding for VSS-signal data is one choice listed in the CVII Tech Stack components (in combination with protobuf, JSON and other choices).
A set of message definition schemas, and prototype code in python have been proposed here.
