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.

I would think that the "heavy lifting" of regulating the actual output power of the charger would be a function of the charge controller itself? Maybe you could tie into / control that somehow with your own microcontroller as brain / interface? Maybe they expose some API, serial, or other method of interfacing with their hardware? What are/were you using for charge controller? I have read a bit here and there about solar (and related moving around and controlling of power, eg. batteries, charge controllers, etc...), as it is something I plan on doing "eventually" although I have no direct experience as of yet. So I will be following this thread with interest.

@monte said in Just found a pair of "old" NRF51822-04 ... any good?: Though the power bug @Nca78 mentioned is easily bypassed with proper software settings. Just don't rely on built in sleep function, because in case of nfr51822 it doesn't disable all hardware and drains power. Sorry @monte, I'm totally n00b . Any link about this? @monte said in Just found a pair of "old" NRF51822-04 ... any good?: Though the power bug @Nca78 mentioned is easily bypassed with proper software settings. Just don't rely on built in sleep function, because in case of nfr51822 it doesn't disable all hardware and drains power. Oh, I know! But I lack time to tinker that much. I've just started on learning on Black Magic Probe and STLink differences and use cases... Maybe I just started the hard way, with a DK it would be, at least, less "pioneeristic".

It is most likely OP amp output you are seeing, connect 5v, resistors as needed and multimeter to resistor output, check if works satisfactory, simple....

Well there is no more sense in any of us wasting any of our valuable resources (time, thought) if it will not affect the design anyway, since you have already ordered the parts. Ignorance is fine, inconsideration for other people's time and effort is not (at least with me). I realize you are in a hurry to build something, we all are, but some times when you hurry you cost yourself time. Or other opportunities like feedback and chance to modify the design. All of which are irrelevant now (at least insofar as this particular project)... We still expect pictures of the completed project.

@Joseph-Gill said in MH-Z19 CO2 sensor: "simplicity" Welcome to the forums, Joseph. I am glad to see you put "simplicity" in quotes. Personally, I think that the level of difficulty that is portrayed towards new people (i.e., "it's easy!") is a little misleading. It is easy if you have "The Knack" but perhaps not so for everyone. @Joseph-Gill said in MH-Z19 CO2 sensor: How hard would it be I think this depends mostly on an honest evaluation of your own skills. You will need to have at least basic understanding of the technologies involved: radio propagation, electronics, coding, etc... Now, all of this can be learned of course, especially if you have interest, and time... So another part of it is also your expectations. If you need something "right now" then you might be happier to go buy something "off the shelf." OTOH, if you enjoy tinkering, learning, and want to eventually be able to build all different sort of devices exactly to your specifications and needs, then MySensors might be the right thing for you. IMO, I think the best approach is to take this as a hobby, slowly acquiring parts (the least expensive ones take a long time to come from China!) as well as knowledge, and eventually increasing your capabilities over a long period of time. And you will learn (IMO) very valuable skills in the process...

@grumpazoid said in Easy PCB Question: I've switched to open source solutions wherever able. Good for you! Personally I prefer the term Free/Libre Software to "Open Source." They are very similar ideas, but not exactly the same. Cheers!
