Hi everyone

I want to read a GS1-128 bar code with odoo v11.

The structure of the code is:

Example: (01)1234567891011(17)010191(21)ABC123789R

where:

Code (01) indicates that the following is the EAN-13 code

Code (17) indicates that the following is the expiration date

Code (10) indicates that the following is the batch 

Do you have any reference about that and how to read it dynamically? Por example, it could be that one product doesn't have batch number but serial number, with another code and without expiration date.

Thanks!
