Hi Mark, I am updating the gemalto driver, and it will support cdc-ecm (AT^SWWAN) instead of PPP for this module. The AT^SGAUTH is already in my code, but not only: several modules use AT+CGAUTH instead. I am not sure when I will upload it, but I hope by the end of this month.
@Denis: about the authentication, we are also modifying the lte core/atom, because some use cases require to have an authentication also for the LTE combined attach. I have a private APN use case that requires it, and it seems it is needed for a Japanese certification. For this, we will use AT+CGAUTH as default (because it is in the 27.007), and AT^SGAUTH for some Gemalto modules. Is this ok for you? thank you, Giacinto On Fri, Sep 7, 2018 at 9:01 AM Mark van der Putten < [email protected]> wrote: > Hi Denis, > > Hmm, are you sure you actually need the AT^SGAUTH? > > I can explain a bit of the reason why I came to AT^SGAUTH modification. > @Giacinto it is module PLS8-E (Testing with firmware 3.017) > > 3G support from providers in NL is at its end.
