Pushed to git master. I also pushed a follow up commit to use mm_get_uint_from_hex_str(): https://cgit.freedesktop.org/ModemManager/ModemManager/commit/?id=d09bc8baaa9fe93a72bb715530b1403a7a81c891 Thanks! > --- > plugins/telit/mm-broadband-modem-telit.c | 6 +- > plugins/telit/mm-modem-helpers-telit.c | 98 > ++++++++++++++++------- > plugins/telit/mm-modem-helpers-telit.h | 3 +- > plugins/telit/tests/test-mm-modem-helpers-telit.c | 73 ++++++++--------- > 4 files changed, 104 insertions(+), 76 deletions(-) > > diff --git a/plugins/telit/mm-broadband-modem-telit.c > b/plugins/telit/mm-broadband-modem-telit.c > index 8b87310..d154fc6 100644 > --- a/plugins/telit/mm-broadband-modem-telit.c > +++ b/plugins/telit/mm-broadband-modem-telit.c > @@ -541,13 +541,13 @@ csim_query_ready (MMBaseModem *self, > response = mm_base_modem_at_command_finish (self, res, &error);
