Regarding the issue of nRF9160's Modem upgrade.

Kenny

Hello, All,

I want to ask about the modem upgrade of nRF9160.

At present, there is no problem with the minor version of the differential package upgrade.

Can the upgrade of the large version be realized?

For example, upgrade from version 1.2.x to version 1.3.x

If it doesn't work at present, can a major version of the modem be upgraded in the future? When will it be?

If it is due to insufficient space, we can add external flash, but this still needs to be supported on ncs.

Hope to get your reply soon！

Thanks !!!

    The version of ncs I currently use is v1.6.0!

    I want to use FOTA to upgrade the modem.

    I see the following description under the "samples/nrf9160/http_update/full_modem_update" example:

    Does this mean that when I want to upgrade from version 1.2.2 to version 1.3.0, I can download the "firmware.update.image.cbor" file in mfw_nrf9160_1.3.0.zip to achieve.

    Because I don’t have a DK version above 0.14.0, so I can’t verify it.

    Yes, this is correct. Note that you will need to upload the .cbor file to a remote HTTP server.

     As stated in the documentation: only versions 0.14.0 and later of the nrf9160 DK support this sample as the prior versions do not have any external flash memory.

    This means that if you have a 0.14.0 you should be good. Please read the release notes for modem fw 1.3.0, and note that it targets the nRF9160 SiP Revision 2 (B1). It is OK to use mfw 1.3.0 in B0 devices for development, but should not be used in production. 

    Kind regards,
    Øyvind
