Hi, I'am trying to work with the Ofono stack in our development around Sagem Hilo GPRS hardware (SAGEM HiC,A.005.00). So I git the sources, make and install it, configure to use the atgen plugin and the atmodem driver. Then I try to execute some tests' scripts :   enable-modem   enter-pin   list-modems At this time I get : [ /generic ]     Powered = 1     Interfaces = org.ofono.VoiceCallManager org.ofono.SimManager     Online = 0     Model = HILO GPRS     Manufacturer = SAGEM     Serial = 352218039849049     Revision = SAGEM HiC,A.005.00     [ org.ofono.VoiceCallManager ]         EmergencyNumbers = 119 118 999 110 08 000 911 112         MultipartyCalls =         Calls =     [ org.ofono.SimManager ]         SubscriberNumbers =         PreferredLanguages = fr         CardIdentifier = 89330118214678482630         LockedPins = pin         PinRequired = none         Present = 1 => and enter in infinite loop : ofonod[3221]: src/modem.c:get_modem_property() modem 0x8142058 property status-poll-interval ofonod[3221]: > AT+CSIM=8,A0F200C0\r ofonod[3221]: < AT+CSIM=8,A0F200C0\r\r\n+CME ERROR: 3\r\n Then if i disable and enable the modem again I get all the Interfaces for a short time : [ /generic ]     Powered = 1     Interfaces = org.ofono.NetworkRegistration org.ofono.Phonebook org.ofono.CallMeter org.ofono.SupplementaryServices org.ofono.CallBarring org.ofono.CallSettings org.ofono.CallForwarding org.ofono.MessageWaiting org.ofono.VoiceCallManager org.ofono.SimManager     Online = 1     Model = HILO GPRS     Manufacturer = SAGEM     Serial = 352218039849049     Revision = SAGEM HiC,A.005.00     [ org.ofono.NetworkRegistration ]         Status = registered         Strength = 75         Name = Orange F         Operators = /generic/operator/20801         LocationAreaCode = 12818         Mode = auto         CellId = 7965     [ org.ofono.Phonebook ]     [ org.ofono.CallMeter ]     [ org.ofono.SupplementaryServices ]         State = idle     [ org.ofono.CallBarring ]     [ org.ofono.CallSettings ]     [ org.ofono.CallForwarding ]     [ org.ofono.MessageWaiting ]     [ org.ofono.VoiceCallManager ]         EmergencyNumbers = 119 118 999 110 08 000 911 112         MultipartyCalls =         Calls =     [ org.ofono.SimManager ]         Present = 0 but after a while I get Online=0 and only the 2 Interfaces SimManager (Present=0 ???) and VoiceCallManager (Emergency call) : [ /generic ]     Powered = 1     Interfaces = org.ofono.VoiceCallManager org.ofono.SimManager     Online = 0     Model = HILO GPRS     Manufacturer = SAGEM     Serial = 352218039849049     Revision = SAGEM HiC,A.005.00     [ org.ofono.VoiceCallManager ]         EmergencyNumbers = 119 118 999 110 08 000 911 112         MultipartyCalls =         Calls =     [ org.ofono.SimManager ]         Present = 0 I put the debug log in attached file and the sequence scripts. Is there the right way to manage ofono working with my Sagem Modem ? Regards, Yoann
