## If you don't know the secret key for your device
21

## 1. Quick checks
21
22
22
-
Secret keys cannot be recovered if lost. Make sure to save any Device ID and Secret key that's provided when adding an Arduino UNO R4 WiFi, Arduino Nano ESP32, or a 3rd party device (ESP32 and ESP8266). If you've lost your secret key, you can generate a new key by [deleting the device](https://support.arduino.cc/hc/en-us/articles/360018324700-How-to-delete-a-device-from-Arduino-IoT-cloud), then adding it again.
23
+
* Try disconnecting and reconnecting your device from your computer or power source.
24
+
* Confirm that the device is powered by checking that the power LED is lit.
25
+
*_Exception:_ The Arduino Opta does not have a power LED. The device can be powered even if no LEDs are lit.
26
+
* If prompted, allow the device to connect to your computer.
27
+
* If Arduino IDE is running, ensure that the serial monitor is closed, or simply close Arduino IDE.

-
## If you get an error when adding the device
31
+
* Ensure you're using a working USB cable that supports data transfer. If possible, try using a different cable.
32
+
* Ensure that any USB hubs or docks are powered and working. If possible, try connecting the device directly to your computer.

1. Make sure you're using a [compatible device](https://support.arduino.cc/hc/en-us/articles/360016077320-What-devices-can-be-used-with-Arduino-IoT-Cloud-).
36
+
* Detach the device from any shield/carrier or external circuitry.

2.[Check if the Arduino Cloud Agent is installed and running](https://support.arduino.cc/hc/en-us/articles/4980687506844), then click **Try again**.
38

## 4. Reset the sketch

> [!NOTE]
35
-
> If you're using a **Chromebook** and [Arduino Cloud for Chromebook](https://support.arduino.cc/hc/en-us/articles/360016495639-Use-Arduino-with-Chromebook), there's no need to install the Arduino Cloud Agent.
40
+
A bad sketch or a non-working Cloud configuration can prevent your computer from programming the board.
36
41
37
-
3. Double-press the reset button on the board to put the board in [bootloader mode](https://support.arduino.cc/hc/en-us/articles/5779192727068-Reset-your-board#bootloader-mode), then click **Try Again**.
42
+
### If you're configuring the device over serial (USB)
38

4.Try uploading an Example sketch (such as _Examples > Built in > 01.Basics > Blink_) in the [Cloud Editor](https://support.arduino.cc/hc/en-us/articles/13809101080732-Open-the-Cloud-Editor).
44
+
Try a **double-press** reset:
40
45
41
-
* If your board isn't detected by the Cloud Editor, see [If your board does not appear in the port menu](https://support.arduino.cc/hc/en-us/articles/4412955149586-If-your-board-does-not-appear-in-the-port-menu).
46
+
1. Find the reset button on the device (typically labeled **RESET** or **RST**).
47
+
2. Press the reset button twice and confirm that the on-board LED pulses. Adjust the timing if needed.
48
+
3. Continue with device configuration. You may find that the configuration is initially able to proceed, but encounters another error. In that case, simply repeat the double-press reset, and attempt to continue. Eventually, Arduino Cloud will overwrite any sketch on the board, solving the issue.
42
49

* If you get an error message when uploading, see [If your sketch doesn't upload](https://support.arduino.cc/hc/en-us/articles/4403365313810-If-your-sketch-doesn-t-upload).
50
+
If you still can't add the device, use Arduino IDE to the Cloud Editor to program the board with a safe sketch (such as the [BareMinimum](https://app.oniudra.cc/sketches/examples?nav=Examples&eid=01.Basics%2FBareMinimum) or [Blink](https://app.oniudra.cc/sketches/examples?nav=Examples&eid=01.Basics%2FBlink) example), then try adding the device to Arduino Cloud again.

### If you're configuring the device over Bluetooth
46
53
47
-
1. Close any instances of Arduino IDE and other applications that may be using the port.
54
+
* Understand that Bluetooth setup requires the board to be running the Arduino Cloud provisioning sketch. When the board is running this sketch, the on-board LED will flash with a "heartbeat" pulse that turns solid when connecting to Arduino Cloud. If your board is not running this sketch, you first need to configure it using USB (Serial).
55
+
* If your board is running the provisioning sketch but still isn't detected, try resetting the Cloud configuration:

***Arduino Opta:** Press and hold the user button (BTN_USER) until the LED (LED_USER) turns off.
58
+
***UNO R4 WiFi:** Connect Pin 2 to GND until the LED turns off.

### "We were not able to configure..." during device set-up
62
+
When configuring your device over serial (USB), other applications can prevent Arduino Cloud from communicating with the device.
54
63
55
-
When adding your device, you may see one of these messages:
64
+
When this happens Arduino Cloud will:
56
65
57
-
*`Couldn't get the firmware info: Start command: exec: "{runtime.tools.fwupdater.path}/FirmwareUploader": file does not exist`
58
-
*`Reset before upload: 1200bps Touch: Open port COMB: Serial port not found`
59
-
*`Can't update firmware: Executing command: exit status 1`
66
+
* Display the **"We could not find any Arduino device"** error page.
67
+
* Display a temporary notification: _"Failed to open serial port. Is the device already in use?"_
60
68
61
-
These errors can occur if the wireless connectivity module on your board is using an old version[^nina] of the WiFiNINA firmware, that cannot be automatically updated by Arduino Cloud.
69
+
Try this:
62
70
63
-
[^nina]: 1.4.1 or earlier. To find out which version is on your board, see [Check the WiFiNINA firmware version](https://support.arduino.cc/hc/en-us/articles/9398559561244-Check-the-WiFiNINA-firmware-version).
71
+
* If Arduino IDE is running, make sure that the Serial Monitor is closed.
72
+
* Close any other applications you think may be using the port.
73
+
* Restart the Arduino Cloud Agent.
74
+
* Restart your computer.

Solve the issue by updating to the latest firmware version using the **Firmware Updater** in Arduino IDE:
76
+
If you still encounter the issue, follow the steps in [Find and stop process blocking a port](https://support.arduino.cc/hc/en-us/articles/4407830972050-Find-and-stop-process-blocking-a-port) to identify and stop the application that's using the port.

## 6. Manually partition your memory Arduino device for Arduino Cloud
73
83
74
-
1. If you haven't done so already, [install the agent](https://create.arduino.cc/getting-started/plugin/welcome).
75
-
2. If you have installed the agent but still encounter this warning, see [If Arduino Cloud Agent isn't detected](https://support.arduino.cc/hc/en-us/articles/360016466600-Warning-To-upload-a-sketch-via-USB-port-make-sure-the-Agent-is-installed-and-running-on-this-computer).

* Arduino Portenta H7 Lite
92
+
* Arduino Portenta H7 Lite Connected
93

If your device has a corrupted or outdated partition scheme, you may encounter one of these issues:
78
96
79
-
## Still need help?
97
+
* A red LED on the device is blinking.
98
+
* Arduino Cloud does not detect the device.
99
+
* A “Storage partition failed!” error is displayed when you attempt to add the device on Arduino Cloud.
100
+
* A “Storage Initialization Fail!” error is displayed when you attempt to add the device on Arduino Cloud.
You can resolve these issues by [repartitioning the memory with a supported partition scheme](https://support.arduino.cc/hc/en-us/articles/16206977438748-Reset-the-flash-memory-on-STM32H747-based-devices).
