nrf9160 modem XFILEWRITE gps almanac

[LordLucan]

Hi,

I see in the nrf9160 1.2.0 AT document there is a command XFILEWRITE that suggests the GPS almanac can be written and persist in the modem.

Can you provide more documentation on this command and the format of the data you can write?

I'd like to improve the TTFF for the GPS. I've got the SUPL GPS client example working and it does indeed speed up TTFF to a few seconds. But I'd like to be able to store that information in the modem in cases where I have no LTE connection or it is simply unavailable for other reasons. That is I want the GPS data to persist. Suggestions welcome!

Regards,

Paul

For anyone looking around for something similar to this feature, here's the pull request implementing support for minimal GNSS assistance consisting of factory almanac, time (from LTE network), and rough location based on MCC.

Best regards,
