Arduino Uno WiFI Rev2 Connection error

Official Hardware UNO Family UNO WiFi Rev2

I get a message "Programmer not responding" Make sure that FirmwareUpdater sketch is loaded on the board."

The "Open Updater sketch" doesn't load.

I'm new to the Arduino world. I apologize if there is a posting for this issue as I have not found it and have looked.

Thanks for any help!

My board does show up in windows 7 device manager as "mEDBG CMSIS-DAP" on COM8
Also, The "ON" led is on and the "L" led is blinking.

First you need to install the Arduino megaAVR Boards package:

  1. Select Tools > Board > Boards Manager from the Arduino IDE's menus.
  2. Wait for downloads to finish
  3. Scroll down through the available packages list until you see "Arduino megaAVR Boards". Click on it.
  4. Click the Install button.
  5. Wait for the installation to finish. If you are prompted about the installation of the driver, approve it.
  6. Click the Close button.

This could be caused by not having the WiFiNINA library installed. You can install it like this:

  1. Select Sketch > Include Library > Manage Libraries... from the Arduino IDE's menus.
  2. Wait for download to finish.
  3. In the "Filter your search..." field, type "wifinina". Press Enter.
  4. Find "WiFiNINA by Arduino" in the search results and click on it.
  5. Click the Install button.
  6. Wait for the installation to finish.
  7. Click the Close button.

Now you can give the firmware update process a try if you like:

  1. Select File > Examples > WiFiNINA > Tools > FirmwareUpdater from the Arduino IDE's menus.
  2. Select Tools > Board > Arduino Uno WiFi Rev2 from the Arduino IDE's menus.
  3. Select the port marked as "Arduino Uno WiFi Rev2" from the Arduino IDE's Tools > Port menu.
  4. Select Sketch > Upload from the Arduino IDE's menus.
  5. Wait for the upload to finish successfully
  6. Select Tools > WiFi101 / WiFiNINA Firmware Updater from the Arduino IDE's menus.
  7. Select the port of your Uno WiFi Rev2 from the ports list in the "WiFi101 / WiFiNINA Firmware Updater" window.
  8. From the "2. Update Firmware" menu, select "NINA Firmware (1.2.2) (Arduino Uno WiFi Rev2)".
  9. Click the Update Firmware button.
  10. Wait for the firmware update process to finish.
  11. Click the OK button.
  12. Close the "WiFi101 / WiFiNINA Firmware Updater" window

Pert, Thank you very much!! Only version 1.2.1 was available but it is communicating.

Oops. Sorry for the confusion. I was referring to a beta tester version of the Arduino IDE which has the new 1.2.2 firmware version when I wrote those instructions. I'm very glad to hear it's communicating now. Enjoy!
