Hello Deepak. As an update, we are just assembling a statically linked C library that can do generic BEJ/JSON encode/decode with input dictionaries and some unit tests. I'm thinking that we could put this in its own repo and then build out the PLDM type 6 handling in the PLDM code as you suggest.
Feedback welcome,
Mike
