Hello Achim,

[quote user="AchimKraus"]o I guess, for many, these revision 1 devices are then going to be use-less.[/quote]

You can still use revision 1 with mfw 1.2.x, which offers a wide range of stable modem functionality. But if you would like to keep the modem firmware up-to-date, continuing with revision 1 is not recommended.

But anyway, last ordering date for revision 1 samples was the 30^th of November 2021, so you can not order such SiPs anymore.

Regards,

Markus

Hello Achim,

[quote user="AchimKraus"]Does Nordic plan to support the nRF9160 HW Revision 1 in future modem firmware updates, or not?[/quote]

nRF9160 HW Revision 1 will only have support with modem firmware versions < 1.3.x. We do not have any plans to add new modem features/functionality to older HW revisions.

Regards,

Markus

Thanks for your answer.

Does Nordic plan to support the nRF9160 HW Revision 1 in future modem firmware updates, or not?

The new version 1.3.0 or 1.3.1 are both marked with ""only for testing and development", if HW Revision 1 is in use.

(With no "production" updates, my feeling is, that the revision 1 parts could not be longer used.)

Hello. For example AT commands AT%XMODEMSLEEP (modem sleep notifications) and AT%XT3412 (periodic TAU notifications) are supported by MFW 1.3.x series and its feature set. These commands are not part of "older" MFW 1.2.x series.

There are no HW limitations with PSM and Revision 1.

It is good to be aware of MFW and NCS compatibility matrix, introduced here: infocenter.nordicsemi.com/.../nrf9160_modem_fw.html
