The standard “AT commands via COM port” communication with my MC7710 modem on Windows 7, should be replaced by a modern Non-AT “Qualcomm’s QMI” protocol.
The modems of MC series are Qualcomm GOBI API compatible, so i’m looking for an GOBI Windows SDK to achieve my goal.
In the mean time i got the “GOBI 2000 SDK” and “GOBI 3000 SDK” from QUALCOMM itself, but my device can’t be detected with both of them because
the “QCWWANConnect” function (from “GobiConnectionMgmt.dll”) returns “6” -> “Unable to detect Gobi device”.
I allready installed the latest QMI drivers “SWI9200X_03.05.24.00bt r5792 carmd-en-10527”. The SW “Air Card Watcher” application communicate without any problems to the modem through QMI protocol.So the device is well configured, i guess.
So what i’m doing wrong?
Should i use any specific Sierra Wireless GOBI SDK?
Is there any other way to talk QMI?
