Arduino nano 33 ble not supported

Hi there,

Looking for some help to trouble shoot an uploading issue.

I'm looking at using an Ardunio nano 33 ble for a project but everytime I upload a code (any code even blank)
it comes with the error that device is unsupported.
It is connected via USB and the cable is full in,
I have installed the Ardunio nRF528x board manager.
port is set to COM8 (the one that shows and disappears when USB is unconnected)
Using the simple example 'blink'
The panel runs like this:

Arduino: 1.8.13 (Windows 10), Board: "Arduino Nano 33 BLE"
Sketch uses 77860 bytes (7%) of program storage space. Maximum is 983040 bytes.

Global variables use 42192 bytes (16%) of dynamic memory, leaving 219952 bytes for local variables. Maximum is 262144 bytes.

Device unsupported

An error occurred while uploading the sketch

This report would have more information with

"Show verbose output during compilation"
option enabled in File -> Preferences.

I've gone through the forums and run multiple searches and 'problem fixed' solutions but I am still getting the same error (i;ve tried pressing reset twice rapidly) any ideas?

I have exactly the same configuration hardware/Software Board.

I'm surprised that your board is not supported while you are compiling :o ...Anyway.

Firstly, go to IDE menu/Tool/Type of board or sommething like this. What do you have in board tab?
Find this => Arduino nRF528x Boards => Arduino NANO 33 BLE should be selected

Next check that your port is correct. Probably Ok since you compiled but check again.
From IDE again, check Tool/COM PORT/ COMx (Arduino NANO 33 BLE).

Is Windows detect "COM serial port" in peripheral device manager// Ports(COM & LPT) //Serial USB Peripheral (COMx) ...something like this
Keep informed

See the sticky at the top of this section for the newer NANO's

Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. Please read and follow the instructions below. Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is frustrating for you and frustrating for us.

  • Your OS and version can be valuable information, please include it along with extra security you are using. Antivirus etc.
  • Always list the version of the IDE you are using and the board version if applicable.
  • Use quote or add error messages as an attachment NOT a picture.
  • How to insert an image into your post. ( Thanks sterretje )
  • Add your sketch where applicable but please use CODE TAGS
  • Add a SCHEMATIC were needed even if it is hand drawn
  • Add working links to any specific hardware as needed (NOT links to similar items)
  • Remember that the people trying to help cannot see your problem so give as much information as you can


  • Ensure you have FULLY inserted the USB cables.
  • Check you have a COMMON GROUND where required. ( Thanks Perry)
  • Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.
  • Try other computers where possible.
  • Try other USB leads where possible.
  • You may not have the correct driver installed. CH340/341 or CP2102 or FT232 VCP Drivers - FTDI
  • There may be a problem with the board check or remove your wiring first.
  • Remove any items connected to pins 0 and 1.


  • Close any other serial programs before opening the IDE.
  • Ensure you turn off any additional security / antivirus just to test.
  • There may be a problem with the PC try RESTARTING it.
  • You may be selecting the wrong COM port.
  • Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.
  • Clear your browsers CACHE.
  • Close the IDE before using any other serial programs.
  • Preferably install IDE’s as ADMINISTRATOR or your OS equivalent


  • CH340/341 based clones do not report useful information to the “get board info” button.
  • NANO (Old Types) some require you to use the OLD BOOTLOADER option.
  • NANO (ALL Types) See the specific sections lower in the forum.
  • NANO (NEW Types) Install your board CORE’s.
  • Unless using EXTERNAL PROGRAMMERS please leave the IDE selection at default “AVRISP mkII”.
  • Boards using a MICRO usb connector need a cable that is both DATA and CHARGE. Many are CHARGE ONLY.

CREATE editor install locations.

  • On macOs ~/Applications/ArduinoCreateAgent-1.1/
  • On Linux ~/ArduinoCreateAgent-1.1/config.ini
  • On Windows C:\Users[your user]\AppData\Roaming\ArduinoCreateAgent-1.1

Performing the above actions may help resolve your problem without further help.
