Hey, there, so I was having a problem with my Arduino Nano clone and the RX LED is always on. And when I leave it just there unused, not touched, not connected and no power. And suddenly... Boom, it works again... Right? Well... The RX LED turns on again if I connect it for a bit, like 20 seconds or so after being connected. And when I publish my code to the Nano. It just errors and says "programmer not responding". Anybody has a solution to this?Thank you.
Did you try the spare unit to see if it does the same thing?
Did you post a schematic?
Did you post an image of the project?
Did you happen to post the well formatted code in code tags?
So far the only solution, from the posted info, is get a real Nano.
So, this only happened on one of the Arduino Nano clone... But. It also just magically happened to my other one when I connected it. I don't know how that happened
Is this the ONLY problem with the board?
It doesn't matter if it's on or not. To tell you the truth, I don't pay much attention to those leds at all...
I can hardly remember if it lights up on my boards or not.
You purchased a "clone" which by definition is a knock-off ... a cheap imitation and you have the nerve to complain about issues on the forum hosted by Arduino Corporate?
Next time buy an Official Nano and be assured that the product functions correctly unless you damage the board. By buying an authentic device, those in this forum have some assurance that the time devoted to helping you with problems is well spent as the official board has known specifications.
Yes, I understand you may be on a budget, but Official Arduino boards pay the bills for Arduino. When someone buys cheap junk and then expect the product to work correctly, they often waste their money (and forum members time.) Everyone developing and engaging this forum should have invested in one official board to assure that everyone in the forum has a standard yardstick to measure results you report in the forum. Buying genuine helps us help you.

Where does OP complain? He/she is only asking for advice as far as I can see.
That is a strange view of open hardware.
It should be a strange view of open source hardware but I have found it is a proper view.
Consider the ESP32. A ESP32 made by HiLetGo strictly adheres to the ESP32's API but the ESP32's made by other manufacturers does not; such as those made by ACIERMC or KeyYEES or WINGONEER or ... Well the list continues. Which is why I think and feel that @mrburnette has presented a proper view of the way it is.
I see no connection to an ESP, they are not open source/open hardware.
Was that always the case? Or did this start happening while you were working on your project?
If the latter, post a proper wiring diagram (photo of paper and pencil drawing is fine and preferred over Fritzing). Include exact details how you have exactly wired all power.
Note that a permanently lit RX led probably indicates that your board is damaged.
I don't think that you can easily fix a damaged board but maybe there is no damage and it has everything to do with what you have connected. So in an attempt to check, disconnect everything except USB and try again.
Well, it appears this ol' fatboy really made a splash in the pool by jumping off the high springboard. Extracting portions of my post for illumination and inspection under the microscope certainly does make me appear to be erratic and maybe even crude in my response.
My intent was to set a tone of expectation for Ops without particularly directing my comment to current Op; perhaps I should have generalized my statement better and I take criticism on that point.
Opinion on hardware:
The Arduino ecosystem is so diluted with clones that forum posts for support on hardware'ish issues become a lengthy Q/A that take extraordinary time to root-out a possible solution. No one could possibly have access to the massive number of clone flavors, so direct inspection of a potential problem is not possible.
Unfortunately, the reality is that the more the forum "assists" with non-official hardware, the more posts that come into regarding clones; the noise being generated is deafening. The clone manufacturers are counting on our goodwill to sell cheap hardware in an unsupported manner; maybe it is not junk hardware, but I suspect there is absolutely no quality assurance.
Then, there are the quality hardware clones from such as Adafruit and Sparkfun who do have support forums but buyers of those product find their way here to the Arduino forum. I am specifically discussing hardware and not coding. The price of the boards and sensors from these major houses include a support cost in the retail pricing.
The Arduino hardware forum is drowning in non-official Arduino dialog. OpenHardware is a most wonderful concept, but the OpenHS Group does not pay Arduino's power, Internet, or server bandwidth bills. As a member here for some time, I can appreciate the costs associated with provisioning of Arduino.cc site. Fellow members, there is a real cost and if we value this portal, we members need to be cognizant of the economics.
Forum.arduino.cc is a great clearing-house, we need to respect the value of the brainpower that is contained within the membership. This forum is a platform, but if you look through the many layers to the foundation, you will see Arduino Corporate. A portion of their profits supports everything this platform represents - different things to different members, but the regulars who are here nearly daily understand the diversity of thought and expression.
I personally do not think we should cut-off the clone owners, but I would be in favor of corraling them into a specific (new) forum section: Clone Hardware, where their questions would be answered on a best effort. The proliferation of clone hardware boards sold as "compatible" with no support is an endangerment to this community; not a recent news headline.

I absolutely respect your opinion,
but disagree in a couple of points, that I will not discuss.
