Am I the only one who is having problems with updates either being lost or seriously delayed? I have several sliders on my IoT dashboard and in my nano 33 IoT device I have simple code that moves a servo arm and echos back to the messenger control that it received the message and what the new value is. If I slide the slider back and forth a few times, it stops moving the servo and the messages stop coming through. Then a couple minutes later suddenly one of the messages comes and the servo moves.
Are you experiencing this too?
Hi @prestonthayne it was a temporary issue, You can check the status of the cloud using this link:
I'm also VERY disappointed with the Arduino IOT cloud. I spent over a month developing a system to monitor the temperature of my batteries, and run heaters when cold. Everything works perfectly when the arduino is connected to my PC with USB cable, but as soon as I moved it to the garage where it's supposed to exist, the connection keeps becoming unresponsive. The WiFi connects no problem, i've checked signal strength in the garage etc. It's just that the MQQT broker keeps becoming unavailable. I have a paid subscription.
The usual link claims that everything should be fine.
Can anyone recommend an IOT service which is reliable?? I'm already looking at adafruit.io.
Hi @nibor65
This is a clear indication that the problem is unrelated to the Arduino Cloud service, but instead cause by some difference between the conditions that exist when the board is connected to your PC vs. when it is in the garage.
If so, changing to a different service is not going to solve the problem.
A common cause of the general symptom "it works when connected to my PC, but not when powered separately" is that the sketch code is dependent on having a serial connection. For example, You'll often see something like this in Arduino sketches:
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
This will make your program stay in an infinite loop until the serial port is opened in Arduino IDE Serial Monitor (or an equivalent application). The reason that is useful is because on native USB boards like yours, the board is not reset when you open Serial Monitor. That means any serial output printed between the time the program starts running and when you get Serial Monitor open will be lost.
In applications where missing that serial output would be a problem, it's useful to add this code to the sketch in order to make the program wait for the Serial Monitor before running.
However, if you are wanting to run your program when the board is not connected to Serial Monitor, you must remove that while loop to allow the rest of the sketch to run.
There is sometimes a more subtle dependency on a serial connection in that the Serial.print calls are acting as incidental short delays that cause the code to work as expected.
Another possible cause of the symptoms you report is that the power source you are using in the garage is insufficient. This can result in intermittent problems. Wi-Fi radio modules draw significant amounts of current in spikes of varying amplitude. So you can have a situation where the power supply is just barely sufficient the majority of the time, but can't handle the occasional more significant draw. When that happens, it isn't equivalent to a full power cycle and the program might be stuck in some bad state. A PC is a very high quality power supply, so you are less likely to experience this type of problem when powering a project from a USB connection to the PC.
I thought of the serial thing. That's not the problem, it works sometimes in the garage.
As for the PSU, I'm using a dedicated mains adapter, and it worked fine a lot of the time.
I suspected that it was because a WiFi extender was in the chain, so I've turned that off and spent a LOT of time moving my router closer. Now the WiFi in the garage is excellent for other devices.
I've also tried using my other Uno R4.
Currently it's consistently crashing after a few cycles:

SO the problem is definitely in the Arduino cloud system. Pleas fix it.
I'm not sure how you get the conclusion that this crash is caused by a problem in Arduino Cloud. It is just as likely to be caused by a bug in the code you wrote.
Immediately jumping to conclusions that there is an external cause for whatever problem you encounter is going to hold you back in any technical endeavors. Embedded systems in general, and IoT devices in particular, are very complex. It is guaranteed that you are going to run into some challenging problems along the way. The key is developing strategies for overcoming those challenges. If your strategy is immediately jumping to: "it must be someone else's fault, there is nothing I can do to solve it", then you are going to get stuck at every obstacle. It might be that some of those problems truly are caused by problems you don't have any way to fix in systems not accessible to you, but many times it will be a problem in the code that is sitting on your hard drive or the circuit sitting on your desk.
Please post your full sketch.
I'll provide instructions you can follow to do that:
- Click the following link to open the list of your Arduino Cloud Things in the web browser:
https://app.arduino.cc/things - Click on the Thing you are referring to in your post.
The Thing's "Setup" page will open. - Click the "Sketch" tab at the top of the page.
The Thing's "Sketch" page will open. - Click the "Auto indent" button on the toolbar:
ⓘ This is done to make the code easier for us to read. - Click on the editor panel of the window.
- Press the Ctrl+A keyboard shortcut (Command+A for macOS users).
This will select all the sketch code. - Press the Ctrl+C keyboard shortcut (Command+C for macOS users).
This will copy the selected code to the clipboard. - In a forum reply here, click on the reply field.
- Click the
<CODE/>icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
- Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the compilation output into the code block. - Move the cursor outside of the code block markup before you add any additional text to your reply.
- Click the "Reply" button to post the output.
If your code uses a library that you imported to your Arduino Cloud account (as opposed to the standard libraries that are pre-installed), please post a link to where you downloaded that imported library from.
