Hi Yanpengwu,

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

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

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

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?

Hi,

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

[quote user=""]Could you help confirm this and give some guidance for implementing this on Windows 11? [/quote]

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

Kind regards,
Andreas
