Dear All: I am a new user of ofono library. Here is the problem I got. Hope that you guys can help me out. First of all, I have a modem which is from sierra wireless MC5728V. this is such an AT command base device. What I did is add the sierra command under /etc/udev/rules.d/ofono.rules +29 ATTRS{idVendor}=="1199", ATTRS{idProduct}=="0028", ENV{OFONO_DRIVER}="sierra" And correct the code in vim plugins/udevng.c + 224 if (g_strcmp0(info->number, "00") == 0){ + 225 mdm = info->devnode; + 226 net = info->devnode; + 227 } And I run ofonod -nd please kindly see the command below
