Are there any constraints for nRF9160 SiP Revision 1 with modem firmware V1.3.1 constraints?

sheddanl

As said in the title. I can see on this page, under "nRF9160 SiP modem firmware"

that: "It can be used for nRF9160 SiP Revision 1, but only for testing and development".

I was wanting to find out why this is, and what kind of constraints I can expect to come across by using this revision of the SiP modem firmware.

Thanks very much!

    Hello Lawrence,

    To clarify - revision 1 should still be able to use all the features on modem firmware 1.3.x,

    yes, you can use all features provided by modem firmware 1.3.x. But since we do not test and certify against revision 1, we can not guarantee that everything will work as desired.

    Would you be able to quantify how much less efficient it would be, perhaps for example running AGPS? No worries if not :)

    Unfortunately, I can not give you any concrete numbers. Under normal circumstances, everything should run as for mfw 1.2.x, but it could be a good idea to be aware of the general current consumption in idle/normal operation mode and possible current peaks.

    Regards,
