We need to come up with a good interface here; there's a lot more parameters to send to the device for A-GPS, and it's slightly different between 3GPP and CDMA. We need at least a SUPL server IP/port or URL, possibly a SUPL-specific APN/authtype/user/pass, and for Qualcomm maybe three gpsXTRA download server URLs and whether auto-download is enabled for gpsXTRA. We'll also need a command to clear any cached GPS assist data. For example, SUPL configuration may require: • Set specific security parameters • Store SUPL certificate in modem • Set specific GPS APN • Set SUPL server’s address and port > > > I also have a Huawei E585 modem, which doesn't support switching to USB > > > mode when plugged in, but apparently support A-GPS.

I'm not aware of custom Novatel commands for GPS, and we haven't reverse engineered any QCDM/DIAG GPS stuff yet. So no. > Any ideas also on turning the Huawei modem into a USB one? The E585 wifi hotspot? I recall that one is actually QMI-based, it's android on the inside, so we may have some hope there.
