Hi all, this is my first experience with this first forum so hopefully I am in the right place. Thanks in advance-Brian
PS: I apologize if I seem short-I have spent way too many days on time reconnect issues!
Issue:
intermittent or not able to connect to the IOT Cloud
Error:
ArduinoIoTCloudTCP::handle_ConnectMqttBroker could not connect to mqtts-sa.iot.arduino.cc:8883
Background:
this issue exists in three different states (Florida, Minnesota, and Wisconsin)
this issue exists on three different ISPs
Controllers:
Arduino Unto R4 Wifi
Nano 2050 Connect (this CPU constantly resets whenever contact is lost with the cloud)
Firmware: (don't tell me this is the problem Arduino tech support...ugh)
Arduino Unto R4 Wifi (was using 1.4.0 and upgraded to 1.5.0-no difference)
Nano RP2040 Connect (this CPU constantly resets whenever contact is lost with the cloud)*
running 1.4.8 because I can't upgrade the firmware through the IDE2.0 or IOT Cloud)
Problem:
this should not be that hard to establish AND maintain a connection to the IOT Cloud
I've done a lot of hunting on the internet already without much success

Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
which are called when their values are changed from the Dashboard.
These functions are generated with the Thing and added at the end of this sketch.

First I know you are only trying to help but I have over 30 hours of labor into this...my patience is growing short...this is suppose to be a hobby, not constant frustration.
What I have done:
I have removed and added the RP2040 three times already including tonight
-firmware is at 1.4.8 and removing/adding to the IOT cloud*
this process DOES NOT UPGRADE THE FIRMEWARE as other tech support has indicated
I normally post with debug level at 4...forgot about that!

I understand your frustration. We will try to help you out.
According to the logs on attempt #1 and #2. I have the following thoughts:
Are both with debug level 4? I guess #1 is got with level 2. (this is important, because I don't know if log #1 means that it didn't connect to the Cloud or it's just a matter of debug level and we should discard it)
The device always connects to the WIFI network
According to #2, the device does connect to the Cloud but disconnects shortly after.
It would be helpful to keep the "Time: XXXX" debug messages you had on your original sketch to understand the timed behaviour.
I know that you might have tried these things, but just in case let me propose a couple of actions to you.
My feeling is that the WIFI is unstable for some reason. I know that this is suboptimal, but I've observed some times that WIFI problems have got fixed by doing a factory reset on the router. Some WIFI configuration modifications affect somehow connectivity. You could try that if it's not a great deal for you.
You can compile and upload the sketch using the Arduino IDE 2.x. For that, open the Cloud sketchbook, pull the sketch and compile it and flash it as usual. Remember to push the sketch if you want to reflect the changes in the Cloud.
Some WIFI issues are caused by insufficient power. Insufficient power can be caused by bad USB cables, USB hubs or broken PC USB ports. How are you powering the device? If you are powering it connected to a USB hub, could you connect it directly to the PC or power the USB hub? Could you connect it to a different USB port or a different PC? Check also the USB cable and replace it by another one just in case too.
Thanks for attempting to help but I think people keep missing this fact!
This is the same results I get in my home of Wisconsin*
*I created a separate wifi network just for IOT with same results!
This is the same results I get in my girlfriend's home in Minnesota
This is the same results I get in my girlfriend's home in Florida
These common results are from THREE different wireless networks and three different ISP using two different type of controllers!
I have already swapped cables and various USB Ports on both the laptops and docking stations.
With that said it I am pretty good at offering solutions and IF I WERE ARDUINO AND ABOUT TO LOOSE A BUNCH OF PEOPLE PAYING OVER $100 dollars a year for a service that sort of works when it likes this is what I would do:
develop an application that would:
check the firewall rules of the network (make sure all traffic is passing in/out of network)
check the delays between the controller and the cloud
verify the firmware of the controller
provides links/option to update the firmware if needed
This app would really save lots of frustration and really help you all out trying to provide technical support for a service that I know you can't admit is "broken".
Now, I am willing to admit that I have been wrong in the past and in a way I hope I am...
As I said in my previous post, I understand your frustration, as this kind of issues are sometimes difficult to diagnose.
I can confirm that the platform works and it is not broken. It is indeed working perfectly for most of the users, but of course, that doesn't mean that there might be some situations like yours that may have issues. Feedback like yours is extremely helpful to help us identify and solve those issues.
Putting the focus on your problem, I've tested your sketch with a Nano RP2040 Connect and it works perfectly fine for me. I will try later with a UNO R4 WIFI but I don't have any at hand now.
May I suggest that you try a couple of things?
To get more information about the WIFI quality, print the WIFI RSSI value along with the millis tick
Something like this: Serial.println("RSSI: " + String(WiFi.RSSI()));
Another test. Can you please add a variable? Just a boolean or integer variable in the Thing. No need to add anything else in the code. After that, just repeat your tests as usual.
For the upcoming logs you send, can you please keep the prints with the "Time"?
Final note: Your suggestion about the application for diagnostics is quite interesting and we will definitely take it into account.
