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. So we switched to PLS8-E (lte)
modem. All seems to be working as expected 3G and also the switch to lte, this
is on stock provider sim card.
But a customer uses a private APN with radius authentication. 3G context
activation is fine but connecting with lte did not happen.
Research by the provider showed that authentication on lte did not happen.

For test purposes hardcode AT^SDAUTH fixes the authentication.
Gemalto is using the atmodem driver. This driver uses PPP. Generally any
CHAP/PAP authentication is done during PPP negotiation phase, not via any
vendor +FOOAUTH commands (although I think there are a few exceptions now)
For modems that use a high-speed interface, the auth parameters are sent during
context setup phase. e.g. after +CGDCONT. See drivers/ifxmodem/gprs-context.c
setup_cb() for an example.
If you do need the SGAUTH, then the logical place to put it would be into
drivers/atmodem/gprs-context.c and use a vendor quirk for gemalto. E.g.
something like:
switch(gcd->vendor) {
case OFONO_VENDOR_GEMALTO:
g_at_chat_send(gcd->chat, "AT^XGAUTH..."....);
break;
}
