Version of MFW deployed for nRF9160 v2

[Jared]

What's the version of the modem firmware programmed at the factory for the ships with the nRF9160-SICA v2?

Here is the feedback I got from the team: 'There is so called Production Test Image (PTI) in nRF-9160-SICA-B1A. The production test image is meant for production tests as its name states. It cannot be used for Modem operation since it will not attach to LTE network. It is necessary to flash a "Normal" modem image in end device production after passing production tests using the PTI.'

The Modem FW version may also be read by using the AT command AT+CGMR.

How to decode the label of the shipping container is described in the Ordering information chapter of the nRF9160 Product Specification.

Are you looking into ordering parts with a specific Modem FW?

It's more of a function whether or not I should update the modem firmware or not for the nRF9160 Feather. v1 hardware I have came with v1.1.0 so having something newer would be great.

I am not sure exactly what you are asking here. In general, it is recommended to use the latest Modem FW version available, given it is compatible with your requirements, for example Mobile network operator certifications(if required) with a corresponding versions of nRF Connect SDK, and LwM2M carrier library.

The Modem FW versions are backwards compatible: Modem FW versions that support GEN2 devices should also support GEN1 devices. MFW1.2.1 or later versions supports both GEN1 and GEN2. MFW1.1.3 also supports both generations.

I think you may have overly complicated my question.

The nRF9160 gets pre-programed with a certain Modem Firmware at the factory. What is that version?

Thanks!

This means there is no usable Modem Firmware in the device when it arrives from the factory.

I'm not talking about the factory. When I purchase through distribution it has a MFW programmed, no? Otherwise I wouldn't be able to solder it down and immediately use it.

So what I'm asking, in a different way, what version of the MFW does the v2 hardware ship with?

[helsing]

I have made the assumption that the SIPs are shipped with the same MFW as they were programmed with at the factory(which are the various PTI images). It looks like one also may order SIPs programmed with a specific MFW for production. If that is desirable, we could guide you.

I have assumed that a Production Test Image (PTI) is usable for testing some limited functionality. Could that be what you have experienced?

You could use +CGMR (or AT%SHORTSWVER) to read the firmware version from the SIP. If you still have some unused v1 SIPs we would find out.
