[XL] Change in pysim[master]: smdpp: add es2p interface + tests - gerrit-log

15 Aug 2025

Hoernchen has uploaded this change for review. ( https://gerrit.osmocom.org/c/pysim/+/40883?usp=email )
Change subject: smdpp: add es2p interface + tests

smdpp: add es2p interface + tests
This adds the es2p interface, integrated with es9p,
with some würgarounds to make the test mode work.
It comes with a few basic tests to ensure it does
not immediately break.
This required some minor refactoring because
the single file grew too large and linter and
type checker kept complaining.
