ASN1C v7.4 Release for 2020 Features Python Code Gen

We are pleased to announce a new major release of ASN1C for 2020, version 7.4.

The main new feature in this release is the capability to generate Python encoders and decoders. Currently supported is generation of code for the BER/DER and JSON (JER) encoding rules. The BER support includes options to generate forward encoders using indefinite lengths and also includes support for parsing and formatting 3GPP TS 32.297 headers as used in standard 3GPP CDR formats.

The new capability provides for generation of 100% Python code, not wrappers around platform-specific DLL’s or shared object files.

We plan to add support for PER, OER, and XER later this year.

In addition to Python, other features in the new release include:

  • Support for 5G ASN.1-based protocols as well as 5G NAS (3GPP TS 24.501)
  • Support for Visual Studio 2019 in the Windows versions
  • The capability to use ASN1C project files created with the GUI from the command-line
