Hi Denis, Thank you for this quick answer. Yes H24 modem expects some raw data in this mode (after having created a TCP or UDP socket). This modem must also support standard way of sending data through ppp. I will start by using this mode. I ve tried but unfortunately AT+CGDATA is not recognized by this modem. I m just starting to play with this modem so I ve to investigate how to configure it properly without this command.

No, a network interface is either already created by the kernel driver when the device is inserted (e.g. on usb data sticks from hso, mbm, etc) or created by the ppp stack managed inside the gprs-context driver. All oFono does is bring the interface up. Regards, -Denis This message was delivered through encrypted mechanism.

Hi Denis, created a ppp. I AT+CGDATA is modem CGDATA, So ATD*99 works fine on H24. How can I pass an option to gprs driver to use ATD*99 instead of CGDATA ? based on vendor as in drivers/atmodem/sms.c? After setting ConnectionContext property "Active" to true I can see that IPaddr and DNS server addr are properly returned by APN. A ppp0 interface is also available. But ppp0 configuration does not seems to be correct when I use ifconfig (IP address is not set etc...). Is ofono responsible of doing this or ppp0 interface must be configured by another layer?

Hi Denis, H24. use drivers/atmodem/sms.c? I have implemented it. I will send you a patch in another email. that be I have successfully setup/configured a gprs connection by using ifconfig. I will have a look to connman. Will try to improve. BR, Christophe This message was delivered through encrypted mechanism.
