Hi, I work on Sierra wireless MC8092 card, with ofono and connman and I have three questions : 1/ I have post on this list 3 weeks ago, about Sierra Wireless MC8092 card, http://lists.ofono.org/pipermail/ofono/2012-August/013450.html . Following your advices I have used at_util_sim_state_query_new as in zte.c and it has worked well. The following patch shows my changes : --- a/plugins/sierra.c 2012-09-06 09:03:15.842101127 +0200 +++ b/plugins/sierra.c 2012-09-06 09:03:03.788099867 +0200 @@ -48,6 +48,7 @@ struct sierra_data { GAtChat *modem; + struct at_util_sim_state_query *sim_state_query; }; static void sierra_debug(const char *str, void *user_data) @@ -119,6 +120,17 @@ return chat; } +static void sim_state_cb(gboolean present, gpointer user_data) +{ + struct ofono_modem *modem = user_data; + struct sierra_data *data = ofono_modem_get_data(modem); + + at_util_sim_state_query_free(data->sim_state_query); + data->sim_state_query = NULL; + + ofono_modem_set_powered(modem, TRUE); +} + static void cfun_enable(gboolean ok, GAtResult *result, gpointer user_data) { struct ofono_modem *modem = user_data; @@ -129,9 +141,12 @@ if (!ok) { g_at_chat_unref(data->modem); data->modem = NULL; + + return; } - - ofono_modem_set_powered(modem, ok); + data->sim_state_query = at_util_sim_state_query_new(data->modem, + 2, 20, sim_state_cb, modem, + NULL); } static int sierra_enable(struct ofono_modem *modem) Are my corrections correct? 2/ As I have explained in post http://lists.ofono.org/pipermail/ofono/2012-August/013460.html I losted the IP address just after I obtained it, it comes from connman which fail with the message "Invalid index and/or address". To workaround this issue, I have change the Sierra modem handling tu use it as an atmodem, see below : --- a/plugins/sierra.c 2012-09-06 09:36:53.478312137 +0200 +++ b/plugins/sierra.c 2012-09-06 09:03:03.788099867 +0200 @@ -260,7 +260,7 @@ ofono_netreg_create(modem, 0, "atmodem", data->modem); gprs = ofono_gprs_create(modem, 0, "atmodem", data->modem); - gc = ofono_gprs_context_create(modem, 0, "atmodem", data->modem); + gc = ofono_gprs_context_create(modem, 0, "swmodem", data->modem); if (gprs && gc) ofono_gprs_add_context(gprs, gc); It works well, I have an internet connection, but I don't really know what are the effects of my change (so I don't like it). Does anybody can explain me how does swmodem work , and why does connman return "Invalid index and/or address"? 3/ I have a last issue, when I boot my system the card is not handle by ofono, I have to reset the Sierra Wireless card to ofono works with it. I have seen in the log that udevng plugins detects the card but ofono doesn't handle it (see the log below) . If you have any ideas or suggestions to solve my issue, feel free to contact me.
