Hi,
Currently, I know that OTA updates for the nRF5340 can be performed using Device Manager and the nRF Connect mobile application. However, if using a PC, is it possible to achieve the same functionality via the command line?
Thanks!!
Mike

Hi Mike,
Is it a Windows PC? There has not been BLE support for this OS in the past, but it looks like that may have changed with the introduction of the smpmgr tool added here: https://github.com/zephyrproject-rtos/zephyr/issues/70871
- https://github.com/intercreate/smpmgr/releases

Hi Vidar,
Yes, that’s correct. I am trying to run this on a Windows PC.
I have already installed the smpmgr tool (version 0.17.0) on my Windows PC and attempted to perform FOTA on my nRF5340 device.
However, I encountered the following issue. The error logs are shown below.

I am not sure whether I am using the smpmgr tool correctly.

Hi Mike,
The packaging of the DFU FW image(s) in a .zip (dfu_application.zip) is a nRF connect specific feature that only works with our DFU tools (in our mobile apps). This scripts expect to receive the binary inside the zip.
Best regards,
Vidar

Hi Vidar,
Are you referring to directly using the zephyr.bin from the example project, or do we need to use additional tools to build the .bin file?
Thanks!!
Mike
Hi Mike,
Just extract the dfu_application.zip file and used the bin contained in the folder. Or you can look for zephyr.signed.bin (zephyr.bin is the unsigned application) in build/<app name>/zephyr
Hi Vidar,
Based on your suggestion, I extracted dfu_application.zip and used the .bin file inside to perform the update, but it seems that I am encountering a similar issue

Hi Mike,
Unfortunately, it looks like the script does not support handling of protected TLVs.
(https://docs.nordicsemi.com/bundle/ncs-latest/page/mcuboot/design.html)
Note: you can use the imgtool command "dumpinfo" to parse the TLVs in your application.signed.bin file: "imgtool dumpinfo application.signed.bin".
Is it an option to use AuTerm which is a GUI app (https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/services/device_mgmt/mcumgr.html#toolslibraries)? Another option is to try this cli tool here https://github.com/thedjnK/qtmgmt
Best regards,
Vidar
Hi Vidar,
I’m not sure how to run AuTerm using the command line. From what I understand, if command-line usage is required, it seems that qtmgmt needs to be used instead.
However, I’m unable to download a pre-built executable of qtmgmt.
I would like to ask whether you could provide an example of commands that have been successfully executed using this tool, so that I can use them for testing purposes.
Thanks!!
Mike
