Re: HE910 + ofono: "Activating context failed with error: Unknown error type"

Hi Marko, I had a similar problem with HE910 and I solved with the following code line immediatly after line 99 in he910.c plugin: 99| g_hash_table_insert(options, "Baud", "115200"); 100| *g_hash_table_insert(options, "Local", "on");* Let me know if it helps. Enrico

It seems to work if I call g_at_chat_send(gcd->chat, "AT&C0", none_prefix, NULL, NULL, NULL) prior. So this would mean that a disconnect or similar action sets DCD to low, and the chats are closed. Does oFono anywhere in the code sets DCD explicitely to low or is it maybe a bug? My patch would look something like this (if it is an HE910 issue only): if (gcd->vendor == OFONO_VENDOR_TELIT) { if(g_at_chat_send(gcd->chat, "AT&C0", none_prefix, NULL, NULL, NULL) <= 0) goto error; } Thanks, Marko Am 2015-06-25 um 11:15 schrieb Marko Sulejic: Hi, I need your help in using a Telit HE910 with ofono (and eventually connman). (I am using ofono 1.16 with HE910 firmware version 12.00.006; connman version is 1.29). My problem is the following ... on startup everything works fine and the ppp0 connection is established, but problems occur in the following case: connmanctl> disconnect cellular_*_context15 Disconnected cellular_*_context15 connmanctl> connect cellular_*_context15 Error /net/connman/service/cellular_*_context15: Input/output error ofonod[5355]: gprs-context.c(244):at_gprs_activate_primary() cid 1 ofonod[5355]: gprs.c(889):pri_activate_callback() 0x1a18c50 ofonod[5355]: gprs.c(893):pri_activate_callback() Activating context failed with error: Unknown error type connmand[3815]: Failed to change property: /he910_0/context15 org.ofono.ConnectionContext.Active: org.ofono.Error.Failed Operation failed The same error happens if I am manually sending connect/disconnect via dbus-send. Only a hard ofono restart can establish the connection again. This behavior happens all the time once a ppp0 disconnect happened (e.g. by removing the SIM; manual disconnect via dbus or connmanctl). A subquestion regarding connman: Can connmand be configured in such a way that on every connection loss, ofono is triggered to reconnect to the Internet?
