Hi Jonas, Thanks for the patch. With your patch, ofono is able to recognize LARA modems. root@imx:/usr/lib/ofono/test# ./list-modems [ /ublox_0 ] Online = 0 Emergency = 0 Features = gprs sim Revision = XX.XX Serial = XXXXXXXXXXX Interfaces = org.ofono.ConnectionManager org.ofono.LongTermEvolution org.ofono.AllowedAccessPoints org.ofono.SimManager Lockdown = 0 Type = hardware Powered = 1 Manufacturer = u-blox Model = LARA-R211 [ org.ofono.ConnectionManager ] Attached = 0 Powered = 1 RoamingAllowed = 0 Bearer = none [ org.ofono.LongTermEvolution ] DefaultAccessPointName = [ org.ofono.AllowedAccessPoints ] [ org.ofono.SimManager ] CardIdentifier = XXXXXXXXXXXXXXXXXX SubscriberNumbers = MobileCountryCode = XXX FixedDialing = 0 MobileNetworkCode = XX PreferredLanguages = en nl LockedPins = BarredDialing = 0 ServiceProviderName = Tata Retries = [pin2 = X] [puk = X] [pin = X] [puk2 = X] PinRequired = none SubscriberIdentity = XXXXXXXXXXXXXX Present = 1 root@imx:/usr/lib/ofono/test# ./enable-modem Connecting modem /ublox_0... root@imx:/usr/lib/ofono/test# root@imx:/usr/lib/ofono/test# root@imx:/usr/lib/ofono/test# ./create-internet-context <APN_name> Found context /ublox_0/context1 Setting APN to <APN_name> root@imx:/usr/lib/ofono/test# ./online-modem Setting modem /ublox_0 online... root@imx:/usr/lib/ofono/test# ./activate-context Error activating /ublox_0/context1: org.ofono.Error.NotAttached: GPRS is not attached Without ofono, I am able to activate the context and get GPRS. With ofono only I am getting below error. Let me know if I am missing any configuration. In source code (drivers/ubloxmodem/lte.c), I found AT commands specific to TOBY module for configuring the PDP context (Eg: UCGDFLT). Whether any flow need to be modified for LARA-R2?

After that, it's just a matter of going through the details of where ofono has issues. that particularly stands out here so I suspect things will mostly just work. Give the patch a try and let me know how it goes.
