1. Okay, you're right, there is no support for upgrading the MCUBoot in nRF52 devices as of yet. Please check out this thread where this topic is explained in detail.

In this Working with nRF52 Series, I'm confusing with "no support for upgrading the bootloader(MCUboot)". What kind of support that they mention about?

this is an valuable answer. Thank you so much

Dear Simon
After I researched on DFU, I realize that with nRF Connect SDK I can upgrade the firmware with a FOTA upgrade. Unfortunately, they tell me that "There is currently no support for upgrading the bootloader (MCUboot) on nRF52 Series devices." so

1. How I can upgrade the firmware when I'm using nRF52832?

On the other hand, with SMP server sample, the mcumgr command-line tool only works with Bluetooth Low Energy (BLE) on Linux and macOS. On Windows there is no support for Device Firmware Upgrade over BLE yet. I wonder

2. Do we have another way to implement the signed image which does not use the mcumgr command-line tool?

Thank you so much

I think you're confusing the nRF5 SDK and the nRFConnect SDK jasonyu.

Simonr does not the dfu only need to be program into the dk? I remember that the dfu example gives you three different way dfu_uart dfu(cloud) dfu_usb_dongle

From what I can tell, it seems like you're looking for something like the smp_svr example found here. We also have this guide for adding a bootloader chain to your application.

So that I check the peripheral_dfu is the example which tells the buttonless function to an application it did not combine dfu

you need to know that the ble devices have 3 sections

DFU SECTION

the onair(cloud) or dfu_uart works here which give you an approach to update your application in different way

Application SECTION

the example peripheral_dfu works here it did not contain dfu as personal it gives a function for your devices that

when a dfu update signal is assigned to your devices normally it works in application section and does not have and reply but buttonless dfu can switch to the DFU SECTION and upload

softdevices Section

basically just softdevices

I've already elaborated my question. I hope you will understand it

please elaborate on your question

sdk means a kit not an example hard to understand what you are talking about
