Hi,

[quote user="kenny.chen"]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.[/quote]

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

[quote user="kenny.chen"]Because I don’t have a DK version above 0.14.0, so I can’t verify it.[/quote]

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

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:

Hello,

What version of NCS are you running? Have you looked at the following samples in NCS 1.6.1?

Or have you read the documentation on full modem firmware update from flash device.

Thanks.

Kind regards,
Øyvind
