Hi everybody, I'm trying to use MC7304 chip with ofono (yes, exactly like Dirk Meul few months ago). It's a QMI-interfaced GSM. I've used Bjørn Mork's patches and with a little hack in setup_sierra (forcing qmi device name), the modem is "detected" and initialized. ... But the "gprs" feature is not detected ! I'm a newbie on ofono project ... Can anyone can explain me how the features detection is done please ? FYI, Please find below ofono debug log : ofonod[1110]: src/modem.c:ofono_modem_create() name: (null), type: sierra ofonod[1110]: plugins/udevng.c:setup_sierra()
