NRF52833 USB_DFU question

[summer]

hi,I used the dfu usb_serial project to update the application，But I don't want to install the nrfutil.exe software because it is too cumbersome for the end customer。May I ask if you have a process related to dfu usb_serial? Or is there a PC reference code?What I want is for me to send a packaged upgrade package to the client and the client to update the application directly with the PC software without the end client having to type the nrfutil dfu usb_serial command to upgrade it。

Hi summer,

What SDK are you using? nRF Connect SDK or nRF5 SDK? I am guessing nRF5 SDK?

The nRF Util source is available here: https://github.com/NordicSemiconductor/pc-nrfutil. Do you think that serves well as a reference code for you?

Your post seems like it is meant to include a link. However, I cannot access it. Did you want to provide a link?

hi，I want to upgrade the software on a PC, but I don't know what the upgrade protocol is.I've seen this link again, but it's not very detailed.(https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v16.0.0%2Flib_dfu_transport_serial.html&cp=7_1_3_5_2_3_0&anchor=lib_dfu_transport_usb),Could you please provide more detailed documents?

The link you sent is for nRF5 SDK v16.0.0. Which SDK version are you on?

I see that the message sequence chat section of that page goes into very deep details. If you find something missing, could you please tell me what it is?

By the way, what is the stage of your project? I just want to let you know our nRF Connect SDK also has DFU over Serial.

Another thing I am unsure about is what is your physical connection from the PC USB port to the nRF5 SoC?

Hi, I'm using SDK17.02, my
bootloader uses dfu_usd program in SDK, and I use nrf52833DK board. I want to make a windows IA to transfer the Dfu. zip package, but I use the USB analyzer to capture the transferred data, I found that the transferred data is different from the data in the Dfu. zip package, I want a detailed protocol document of nrfutil dfu and DK board transfer
