Hi,                 For one of the IOT project, I am using SIM7100E mini PCIe module. I am using connman(1.36) and ofono(1.26) to establish cellular connection. I am seeing that the same module is sometimes identified as gobi and sometimes as sim7100 by ofono.  Attached the logs for reference: # lsusb Bus 003 Device 008: ID 1e0e:9001 Qualcomm / Option # /usr/lib/ofono/test/list-modems [ /sim7100_0 ]     Type = hardware     Emergency = 0     Model = SIMCOM_SIM7100E     Serial = 866802021517042     Interfaces = org.ofono.SmartMessaging org.ofono.PushNotification org.ofono.MessageManager org.ofono.NetworkRegistration org.ofono.ConnectionManager org.ofono.Phonebook org.ofono.CallMeter org.ofono.SupplementaryServices org.ofono.CallBarring org.ofono.CallSettings org.ofono.CallForwarding org.ofono.MessageWaiting org.ofono.AllowedAccessPoints org.ofono.VoiceCallManager org.ofono.SimManager     SystemPath = /sys/devices/soc0/soc/30800000.aips-bus/30b30000.usb/ci_hdrc.2/usb3/3-1/3-1.3     Manufacturer = SIMCOM INCORPORATED     Online = 1     Powered = 1     Features = sms net gprs ussd sim     Revision = 4534B06SIM7100E     Lockdown = 0 # /usr/lib/ofono/test/list-modems [ /gobi_0 ]     Serial = 866802021517042     Interfaces = org.ofono.LongTermEvolution org.ofono.SmartMessaging org.ofono.PushNotification org.ofono.MessageManager org.ofono.NetworkRegistration org.ofono.ConnectionManager org.ofono.SupplementaryServices org.ofono.NetworkMonitor org.ofono.RadioSettings org.ofono.MessageWaiting org.ofono.AllowedAccessPoints org.ofono.SimManager org.ofono.VoiceCallManager     Online = 1     Emergency = 0     Features = sms net gprs ussd rat sim     Revision = M9615A-CETWTBZM-6.0.15255  1  [May 13 2016 01:00:00]     Type = hardware     Manufacturer = QUALCOMM INCORPORATED     Powered = 1     Model = SIMCOM_SIM7100E     SystemPath = /sys/devices/soc0/soc/30800000.aips-bus/30b30000.usb/ci_hdrc.2/usb3/3-1/3-1.3     Lockdown = 0 I looked into the source code of ofono. Gobi and sim7100 both are implemented as plugin. From the source code (plugins/udevng.c) it looks like the module should use sim7100 plugin. But it is not always the case for me. { "gobi",               "qmi_wwan"                                     }, { "gobi", "qcserial"                                             }, { "sim7100",        "option",             "1e0e", "9001"  }, Further if the module is identified as gobi, I am able to connect to the internet. If it is identified as sim7100, the module gets disconnected and connected again (reset) whenever I am trying to activate the context.

May I know what is the issue here and any idea on how to fix this issue will be helpful. Mit freundlichen Grüßen / Best regards *Vinothkumar Eswaran BEG-PT/PJ-EL* _______________________________________________ ofono mailing list ofono(a)ofono.org https://lists.ofono.org/mailman/listinfo/ofono
