nRF5340: BLE FOTA from Windows

[Yanpengwu]

Hi Support Team,

Our product is based on nrf5340 and ncs V2.5.2. I developed a Windows application(based on .NET8.0 and Windows SDK11) to provision and configure the system via BLE, and it works well.

Now, I want to add the BLE FOTA on this Windows application. After enabling the CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU on the target, I found it seems that the mcumgr did not support the BLE FOTA on Windows? Could you help confirm this and give some guidance for implementing this on Windows 11? I believe there is a solution to do this because the FOTA client on the Windows is a very common requirement. Thank you very much.

Best regards,
Yanpeng Wu

Hi,

MCUMgr BLE FOTA is unfortunately not supported on Windows. BLE FOTA support with mcumgr is only for Linux AFAIK.

Could you help confirm this and give some guidance for implementing this on Windows 11?

Unfortunately no. The limitation is on Windows' side. See  McuMgr via BLE with a Windows machine  

Kind regards,
Andreas

Hi, in the MCUmgr Tools/libraries, it seems the tools AuTerm and smpclient can run on Windows to interact with the SMP server on target. Is it feasible? Could you share any sample or hints for this if possible?

[Yanpengwu]

Both AuTerm and smpclient do not provide CLI tool I needed for this purpose. I close this ticket.

I found that a Python-based tool smpmgr can do this, FYI.

Hi Yanpengwu,

Could you please share the update process? Because I’m encountering an ‘Inspection of FW image failed’ issue.”
