nrf52840 usb dongle setup issues

SethFlannigan last edited by

I've recently purchased an nrf52840 usb dongle and am having trouble getting it to show up on my com ports list as I can't seem to find a device driver for it. I'm trying to use the nrfutil on the command line and it requires the com port or the device's serial number and I can't find either. Is anyone familiar with this device? Any help would be appreciated.

Edit: I used a program (USBDeview) to list the connected usb devices and their info and "serial number" and "port" are blank for the nrf52840 dongle. Several other devices do not show a serial number or port so I can't be sure that this means anything.

@Nca78 said in Looking for very simple rocker switch: So huge that the pins are in fact way too big (0.8*1.2mm section) to fit on a breadboard or in a Dupont connector Hahaha, that's hilarious Thanks for trying though, really appreciate it!

@LastSamurai, Very nice project you have here! Thank you for taking the time to post/share your work! At first I thought it might be exactly what I was looking for, but reading through everything now I am not so sure. I have been studying various ways (Wi-Fi, 433/315 Mhz RF, MySensors) to implement controlling RGB lights and I initially thought Wi-Fi (while readily available, easy, and cheap) might be too "slow" in response time, which got me thinking to use MySensors (with NRF24) instead, which led me to this thread (among others). Something concerned me though, I see in your GitHub for this project you stated: Project frozen/final - This project is done from my side. It has been working for years but I switched to another solution so I won't update this anymore. and on your OpenHardware page: Update2: They have been running for about 2 years now mostly without problems. The only disadvantage is that my Mysensors network overall is quite "slow" (~1s reaction time). I am currently experimenting with Wifi RGBWW controllers (H801) so there wont be to many more updates to this project Which made me want to ask you what you are using now? It seems to me that those MagicHome type Wi-Fi (or RF) RGB controllers would be pretty hard to beat price wise, I don't think I could implement similar functionality (including packaging, etc.) for the same amount of money, and that's before even counting my time. Also I am still struggling with reliability of my MySensors network in general, but I hope to be able to still solve this as it seems that many others have been able to (but that is a different subject altogether).

I haven't read this myself, but it looks interesting if someone has access to an active ieee subscription: https://ieeexplore.ieee.org/document/8890666/

@mfalkvidd I'm impressed that they've pre-sold over ten thousand of them. Changing a watch battery isn't particularly easy, especially on a waterproof watch, because AFAIK doing so generally ruins the waterproofing seals. Dave Jones may have underestimated the hassle factor. Also, there's a watch that was made by the authors of "The art of electronics" that the authors say consumes just 1 microamp, and that was more than a decade ago. So, bluetooth aside, a TEG should generate more than enough to run a watch like that. I don't doubt that at least some amount of bluetooth or ANT or some other kind of radio communications could be supported. Maybe not a lot, but at least something. It's easy to forget that the original consumer LED watches would light up only when you pressed a button, and yet they sold anyway. If you did it that way, then it should be easy, and it would leave more of a budget for the radio communications.

@secantscope I understand - It is a few years since I looked into this and then the only conclusion I could make was to take a meter and interface with usb. It would be more work and my needs case didn't warrant that at the time. I am sorry I could not be of more help in this, but it just seems to be the way things have been for a while. Maybe in the future things will change. As @nagelc suggested a lesser sensor could be used and you could calibrate it yourself. Seems little other options really. (Now I said that you just wait for a killer posting with just the thing you want linked) !!!
