Dear baseband-developers team,
Thank you for your advise.
Would you please advise  — in order to learn / understand structure of C coding in Osmocom things, which relatively easy osmocom sub-project would you advise me to start to / learn?
I mean instead of rush and head hit against some difficult C codes in Osmocom  — to have relatively easy kind of «sub-project» of Osmococom for start learning purposes….
Thank you
