Sierra Aircard 250U. GPS init AT-comand

Hi everyone

I own usb device AirCard 250U by Sierra Wireless. It was bought in Sprint brandshop, and in-stock there is user interface program only for Windows and Mac. Without this soft I couldn’t initialize GPS function. But I need to use this device in Ubuntu Linux.

I know, that it’s possible to initialize GPS by sending an AT command.
I do such trick with Sierra Wireless MC5725. For MC5725 command is “AT!GPSTRACK=1,255,50,1000,1”

Would anybody tell me something about this?


So… Try to answer to myself by myself…

Command for start gps session is
AT!GPSFIX=1,255,10
