Hi,
I’m trying to set up a Windows device with an EM7455 to obtain GPS and 4G data, and I’m in the UK if that makes a difference.
I was able to get GPS fix (though longer TTFF was than I would like) when using the latest generic firmware (2.38.00.00) with my test SIM but now I have the client-supplied Vodafone SIM and Windows “helpfully” flashes the Vodafone firmware (2.24.03.00) on startup and now I am unable to get a GPS fix.
Does anyone know if it’s possible to stop Windows from flashing the Vodafone FW so I can keep the latest generic (which I guess has some fixes for GPS which are unavailable in the older Vodafone version)? If I am able to do this, is it documented anywhere what’s actually in the Vodafone FW that makes it different from generic (besides being older), and is it possible to manually apply these changes to make latest generic work on vodafone network if it doesn’t by default?
Thanks!
