Thats cool!. As the tool is particularly designed for linux, i couldn't be much sure on windows

As explained here github.com/.../mynewt-mcumgr
mgmt (the core layer of mcumgr stack) can work with SMP/Bluetooth Transport.
But I can't say much about OTA DFU, because I didn't get inside it. I will do it in my next project

Thanks a lot, i would check that out!.

Do u think this would work properly on Windows for DFU over air through BLE, rather than serial?

Just had a thought.

Hi Mohan,
At this moment this is all I can say you. Time is going to flight..

Install Go and build MCUmgr CLI on Windows host
---------------------------------------------------------------
1. Download the current binary for Go from https://golang.org/dl/
2. Open the MSI file you downloaded and follow the prompts to install Go.
If this gives one of several errors try this
open the Command Prompt as administrator and write the command
> msiexec /i "C:\<anyPathTo>\go<x.y.z>.windows-amd64.msi"
This will run the MSI installer of your program without errors.
3. Check installation works
> go version
4. Download mcumgr source zip from github.com/.../mynewt-mcumgr-cli
5. Unpack and rename resulting directory to $GOPATH/src/mynewt.apache.org/mcumgr
You can find GOPATH under the environment variable list

6. Go in the source directory and build
> cd C:\Users\gabriele\go\src\mynewt.apache.org\mcumgr\mcumgr
> go build
7. Check
> mcumgr version
mcumgr 0.0.0-dev
8. Use it
> mcumgr -t 20 --conntype serial --connstring=COM2 <cmd>
To make DFU, copy the new FW release (signed image app_update.bin) into the folder
C:\Users\<user>\go\src\mynewt.apache.org\mcumgr\mcumgr
Open a commad shell there and use mcumgr to perform DFU.
For example
> mcumgr -t 20 --conntype serial --connstring=COM2 image upload <path to>\app_update.bin

I've found the fucking culprit
CONFIG_UART_0_NRF_FLOW_CONTROL=y
This switch prevents mcumgr client to work properly on Window 10 host. At this moment I don't know why.

If I rebuild & flash the smp_svr project (zephyr/samples/mgmt/mcumgr/smp_svr/) the mcumgr CLI works with Windows

If I copy the main.c of smp_svr into my project then rebuild & flash, the mcumgr CLI does not works with Windows

No problem with Linux host in either cases.

Ok, then I am sorry. It was the end of the day, and I thought it was better to provide something, rather than nothing.

Can you please try to use the Zephyr MCU manager, which is linked from this guide?

You can test it using the SMP Server example. Let me know if that doesn't work on your Windows computer.

Hello Edvin,

the ticket you refer to has nothing to do with my issue.
In that post the guy has a problem with the software of the target board.
In my case the problem is the mcumgr CLI, which runs on the Host PC.
With Linux host it works fine, with Windows I have NMP timeout.

Hello,

Can you please try to go through this ticket and see if there is any useful information there? I am sorry, but I am not very familiar with apaches mcumgr, but I see that he was struggling with the same NCP timeout in the beginning of the discussion.

Best regards,

Edvin

It seems data transmitted over the serial are the same, even though on Windows I get the error.
