Hi all, Just a quick note: doing an attach via a PC/SC reader and commercial SIM cards is already supported via SAP.
SoftSIM[1] could be used to present the card inserted into the reader using SAP (as a socket) and osmocom is capable of connecting to the socket if configured. Kind regards, Domi [1] https://osmocom.org/projects/baseband/wiki/SoftSIM 2018. márc. 16. dátummal, 19:13 időpontban Vadim Yanitskiy <vyanits...@ptsecurity.com> írta: > Hello Victor, > > > I would like to congratulate and thanking you for the excellent > > job you did on the osmocom TRX/gr-gsm project. > > Thanks.
