I can't re-enable a = previously disabled context. Here the command to reproduce the issue: --------------------------- dbus-send --system --type=3Dmethod_call --print-reply --dest=3Dorg.ofono = /simcom_0/context1 org.ofono.ConnectionContext.SetProperty string:"Activ e" variant:boolean:true dbus-send --system --type=3Dmethod_call --print-reply --dest=3Dorg.ofono = /simcom_0/context1 org.ofono.ConnectionContext.SetProperty string:"Activ e" variant:boolean:false dbus-send --system --type=3Dmethod_call --print-reply --dest=3Dorg.ofono = /simcom_0/context1 org.ofono.ConnectionContext.SetProperty string:"Activ e" variant:boolean:true --------------------------- and bellow, the log: --------------------------- ofonod[10347]: Modem: > AT+CGDCONT=3D1,"IP","gprs.swisscom.ch"\r ofonod[10347]: Modem: < \r\nOK\r\n ofonod[10347]: drivers/atmodem/gprs-context.c:at_cgdcont_cb() ok 1 ofonod[10347]: Modem: > AT+CGDATA=3D"PPP",1\r ofonod[10347]: Modem: < \r\nCONNECT 115200\r\n ofonod[10347]: drivers/atmodem/gprs-context.c:at_cgdata_cb() ok 1 ofonod[10347]: drivers/atmodem/gprs-context.c:setup_ppp() ofonod[10347]: drivers/atmodem/gprs-context.c:ppp_connect() ofonod[10347]: IP: 10.146.60.102 ofonod[10347]: DNS: 195.186.216.33, 195.186.152.33 ofonod[10347]: src/gprs.c:pri_activate_callback() 0x108698 ofonod[10347]: plugins/udev.c:udev_event() subsystem net add ofonod[10347]: plugins/udev.c:udev_event() subsystem net finished ofonod[10347]: plugins/udevng.c:check_modem_list() ofonod[10347]: = drivers/atmodem/gprs-context.c:at_gprs_deactivate_primary() cid 1 ofonod[10347]: plugins/udevng.c:remove_device() = /sys/devices/virtual/net/ppp0 ofonod[10347]: plugins/udev.c:udev_event() subsystem net remove ofonod[10347]: plugins/udev.c:remove_modem() /devices/virtual/net/ppp0 ofonod[10347]: plugins/udev.c:udev_event() subsystem net finished ofonod[10347]: drivers/atmodem/gprs-context.c:ppp_disconnect() Reason: 6 ofonod[10347]: Modem: < \r\nNO CARRIER\r\n ofonod[10347]: drivers/atmodem/gprs-context.c:at_gprs_activate_primary() = cid 1 ofonod[10347]: src/gprs.c:pri_activate_callback() 0x108698 ofonod[10347]: src/gprs.c:pri_activate_callback() Activating context = failed with error: Unknown error type --------------------------- I read the code, added some logs and found the function = at_chat_send_common() doesn't do his job because chat->command_queue is = NULL. I guess chat->command_queue is free and set to NULL in = chat_cleanup(struct at_chat *chat) but I don't dig more why this = function is call... Any ideas ?
