Unable to Update Alvik Firmware

Official Hardware Education Alvik
1

When trying to update the Alvik's firmware at alvikupdate.arduino.cc using Chrome and Edge on Mac nothing happens when pressing the "connect" button. It shows that the ESP32 is paired but after pressing "connect" the update button remains greyed out. Any guidance would be greatly appreciated. Thank you.

Sorry about your problem, after careful consideration it appears your wiring may be the root cause. Since hardware is involved, it’s crucial to provide an accurate, annotated schematic of your circuit as it is currently wired. Please note that Fritzing diagrams are not considered proper schematics; they are wiring diagrams and are often not helpful for troubleshooting.

What to Include:

  1. Annotated Schematic: Show all connections, including power, ground, and power sources. This helps us understand how your circuit is set up and identify any potential issues.
  2. Technical Information Links: Provide links to technical documentation for each hardware device used in your setup. Avoid links to sales sites like Amazon, as they usually lack the necessary technical details. We need complete specifications to help you effectively.
  3. Additional Information Needed: If the above details are incorrect, more information is required. Tell us what hardware and software you are using, the format of any data (like map data), and how your system determines its position. For example, if your project involves a robot, describe how it navigates and what computers are involved.
  4. Code Without code we cannot see the interrelationship between the code and hardware.

Why This Matters:

We have no way of knowing the specifics of your setup unless you provide that information. Clear and detailed descriptions enable us to offer the most accurate help possible. Without these details, it’s difficult to diagnose and solve the issues you're experiencing. You should check this link: How to get the best out of this forum

Hi,

I do not have any wiring or code. The Arduino ESP32 is just mounted to the Alvik. I'm not trying to run a sketch, just updating the firmware for the Alvik.

Below are the right steps to update Alvik firmware:

  1. Visit https://alvikupdate.arduino.cc.
  2. Connect Alvik to your computer.
  3. Turn ON your Alvik.
  4. Click the "Connect" button.
  5. A pop-up window will appear prompting you to select the COM port. Choose the correct port and confirm.
  6. Once connected, click the "Update" button and wait for the process to complete.

If this does not work, then:

  1. Turn OFF your Alvik ( or you remove Nano ESP32 from the Alvik robot and do step 2 below).
  2. Connect Nano ESP32 to your computer.
  3. Reflash MicroPython bootloader on it following this guide.
  4. try to follow initial steps to update the firmware again.
