Hi, When i want to change a Property (eg. APN) of an Active ConnectionContext. I first deactivate the context, wait for a reply then set the property and re-activate the context. The problem is i'm already trying to re-activate the context, before oFono gets a "NO CARRIER" from the modem. oFono tries to send AT+CGDCONT, but get's a "NO CARRIER" response and fails to activate the context. Is there a way to tell if it's ready to re-activate? Should oFono wait for the "NO CARRIER" before it sends a reply to the deactivation? Here's a log of the problem Jan 4 22:14:38 ofonod[3022]: drivers/atmodem/gprs-context.c:at_gprs_deactivate_primary() cid 1 Jan 4 22:14:38 ofonod[3022]: PPP: lcp: pppcp_generate_event: current state 9:OPENED Jan 4 22:14:38 ofonod[3022]: PPP: event: 3 (Close), action: 8224, new_state: 4 (CLOSING) Jan 4 22:14:38 ofonod[3022]: PPP: lcp: pppcp_initialize_restart_count: current state 9:OPENED Jan 4 22:14:38 ofonod[3022]: PPP: lcp: pppcp_send_terminate_request: current state 9:OPENED Jan 4 22:14:38 ofonod[3022]: PPP: ipcp: pppcp_generate_event: current state 9:OPENED Jan 4 22:14:38 ofonod[3022]: PPP: event: 1 (Down), action: 201, new_state: 1 (STARTING) Jan 4 22:14:38 ofonod[3022]: PPP: gatchat/gatppp.c:ppp_enter_phase() 5 Jan 4 22:14:38 ofonod[3022]: plugins/udevng.c:remove_device() /sys/devices/virtual/net/ppp0 Jan 4 22:14:38 ofonod[3022]: plugins/udev.c:udev_event() subsystem net remove Jan 4 22:14:38 ofonod[3022]: plugins/udev.c:remove_modem() /devices/virtual/net/ppp0 Jan 4 22:14:38 ofonod[3022]: plugins/udev.c:udev_event() subsystem net finished Jan 4 22:14:38 ofonod[3022]: PPP: lcp: pppcp_process_terminate_ack: current state 4:CLOSING Jan 4 22:14:38 ofonod[3022]: PPP: lcp: pppcp_generate_event: current state 4:CLOSING Jan 4 22:14:38 ofonod[3022]: PPP: event: 11 (RTA), action: 802, new_state: 2 (CLOSED) Jan 4 22:14:38 ofonod[3022]: PPP: lcp: pppcp_this_layer_finished: current state 2:CLOSED Jan 4 22:14:38 ofonod[3022]: PPP: gatchat/gatppp.c:ppp_enter_phase() 0 Jan 4 22:14:38 ofonod[3022]: PPP: gatchat/gatppp.c:ppp_dead() Jan 4 22:14:38 ofonod[3022]: src/gprs.c:assign_context() Jan 4 22:14:38 ofonod[3022]: src/gprs.c:assign_context() gprs[0x557f80] context_driver[0x556a40] Jan 4 22:14:38 ofonod[3022]: drivers/atmodem/gprs-context.c:at_gprs_activate_primary() cid 1 Jan 4 22:14:38 ofonod[3022]: Modem:> AT+CGDCONT=1,"IP","test"\r Jan 4 22:14:39 ofonod[3022]: PCUI:< \r\n^RSSI:17\r\n Jan 4 22:14:40 ofonod[3022]: PCUI:< \r\n^MODE:5,4\r\n Jan 4 22:14:40 ofonod[3022]: Modem:< \r\nNO CARRIER\r\n Jan 4 22:14:40 ofonod[3022]: drivers/atmodem/gprs-context.c:at_cgdcont_cb() ok 0 Jan 4 22:14:40 ofonod[3022]: src/gprs.c:pri_activate_callback() 0x55dc88 Jan 4 22:14:40 ofonod[3022]: src/gprs.c:pri_activate_callback() Activating context failed with error: Unknown error type

Hi Denis, with the patch i don't get a reply when deactivating the context. From the on it's not possible to activate the context, because the operation is still in progress. This is a log of the deactivation: Jan 1 03:13:05 ofonod[6856]: drivers/atmodem/gprs-context.c:at_gprs_deactivate_primary() cid 1 Jan 1 03:13:05 ofonod[6856]: PPP: lcp: pppcp_generate_event: current state 9:OPENED Jan 1 03:13:05 ofonod[6856]: PPP: event: 3 (Close), action: 8224, new_state: 4 (CLOSING) Jan 1 03:13:05 ofonod[6856]: PPP: lcp: pppcp_initialize_restart_count: current state 9:OPENED Jan 1 03:13:05 ofonod[6856]: PPP: lcp: pppcp_send_terminate_request: current state 9:OPENED Jan 1 03:13:05 ofonod[6856]: PPP: ipcp: pppcp_generate_event: current state 9:OPENED Jan 1 03:13:05 ofonod[6856]: PPP: event: 1 (Down), action: 201, new_state: 1 (STARTING) Jan 1 03:13:05 ofonod[6856]: PPP: gatchat/gatppp.c:ppp_enter_phase() 5 Jan 1 03:13:07 ofonod[6856]: PCUI:< \r\n^MODE:5,4\r\n Jan 1 03:13:07 ofonod[6856]: Modem:< \r\nNO CARRIER\r\n Jan 1 03:13:08 ofonod[6856]: PCUI:< \r\n^RSSI:18\r\n Jan 1 03:13:11 ofonod[6856]: PCUI:< \r\n^RSSI:18\r\n
