3 years ago I'm now trying nrfutil on windows - man that was also a battle to install.
So trying to flash the openbootloader nrfutil dfu usb-serial -pkg uf2_bootloader-0.2.13-44-gb2b4284-nosd_signed.zip -p com4 as per YOUR DOC
Guess what another error:
Usage: nrfutil dfu [OPTIONS] COMMAND Try 'nrfutil dfu --help' for help.
Error: No such command 'usb-serial'.
I mean apart from the com4 bit I am just copying the text.....

3 years ago So changed usb-serial to serial
Now getting a whole heap of messages :

I'll try and change the com4 parameters in device manager
man oh man.

I noted: Target is not in DFU mode. Ground DFU pin and RESET and release both to enter DFU mode. How can I do that on a usb dongle, I thought that was the point.

3 years ago So just to make clear: I take the device, hold down the reset button, insert it into a usb port. The top left led (at the usb port is green, the other led flashes red a couple of times and then goes green. I am in DFU mode right?

3 years ago I can now convert hex files to uf2 files. So tried blinky, but can't see any led blinking every 500ms - I assume that is what it should do.
nrfConnect |programmer still doesn't recognise the device. Lost count of the things I've tried, but nrfutil on windows didn't work under Python. I eventually found a Nordic windows executable that does what it should, but not with my device. I've now ordered some proper nrf dongles and this is going in the bin. A waste of my money, a waste of my life and simple a waste.

2 years ago Are there any updates on this issue? I am currently having the same problem.

2 years ago Sorry, no. I'd forgotten all about it. I later tried the nrf52840 dongle and dk board and though I got some things working, it turned out to be just as much a nightmare as this thing. If you look on the Nordic site you will find some of my posts and unhappiness :sigh. I do have a word document that explains how I got VS Code set up on Windows for the nrf 52840 if you want a copy, though it's not fully edited. My biggest block was when I found that without seggers and stuff I didn't understand I found I couldn't get buttonless? OTA to work on the dongle. I am about to dip my feet into BT again, but dreading it. Gordon
I've bought a nrf52840-mdk-usb-dongle from China. I've downloaded nrf connect onto a windows machine and a linux machine. I've tried inserting into usb and inserting into usb with reset pin held down.
On Linux nrfconnect|Programming I get message : Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.
On Windows I get message : Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.
I've spent days trying to follow instructions for installing wpantund at https://wiki.makerdiary.com/nrf52840-mdk-usb-dongle/getting-started/ and gave up because it is too flippin complicated. I only want to make a flashing light not land a rover on Mars....
I've then looked at other solutions such as using nrfUtil. I can't get anywhere because the instructions suddenly assume knowledge that I haven't got or don't know how to resolve and no amount of searching on google reveals an answer that helps.
For instance I thought maybe if I load the open bootloader I might get somewhere nrfutil dfu usb-serial -pkg uf2_bootloader-0.2.13-44-gb2b4284-nosd_signed.zip -p
How the hell do I find the?????
I tried /dev/ttyACM0 which seemed reasonable, no joy just more incomprehensible errors.
So please tell me I've bought a knock off piece of junk (though it does what flash red a few times etc) or I'm doing something so ridiculously foolish that I deserve to be flamed.
So please tell me what to do to get let's say nRF Connect running on Windows for this device. Now that can't be hard can it?
