Esp32 nano is not detected on laptop

Hi there, I'm trying to my esp32 nano; however, its not able to connect to my laptop (windows 11).
Is there a way to fix this?

2

Have you installed the Nano ESP32 (via Boards Manager) ?

3

yes, I downloaded the one from Arduino

Check your cable; it might be a charge only cable and you will need a data/sync cable. I'm not sure what the Arduino Nano ESP32 board uses? MicroUSB? USB-C?

Try these steps:

  1. Do complete Uninstall Arduino IDE and then re-install the Arduino IDE (use Arduino IDE 2.3.2). Make sure that you install all the dependencies that shows up after the installation. If your machine is running Windows 11, check How to Fix Arduino Problem on Windows 11 and grant the IDE admin right.

  2. Install your board's Package Core, it contains the board's driver.

  3. Use a good quality data USB cable to connect the board to the computer without anything connected or wired to the board. Charging/bad USB cable will make it impossible for your computer to detect your board.

  4. Make sure you select the board and the port it is connected to before uploading a sketch.

  5. If #1-4 above fails to solve it, double tap the reset button fast and check the status of the onboard "L" LED. If the onboard LED fade in and out slowly (pulsating), upload an example sketch (Blink LED) from the IDE to the board.

I'm getting error 74 and I'm still not not connected.

I don't think its that wire because I recently bought one that had data transfer and its powering the esp32 nano.

Did you ever figure out the connection issue?

No, I switched to a esp32 wroom

I can't explain why, I am searching for another problem that's caused by the same thing. But first, it is not my solution and from another post.

So you can connect and solve it by following the next steps:

  1. connect the Arduino nano ESP32 with a data transmit proof USB-C cable with your computer.
  2. connect the B1 pin with the ground (the LED should be much too bright green at this moment)
  3. press the reset button (nothing should happen)
  4. disconnect the B1 pin from the ground (the much too bright LED should turn the brightness down and turn purple)
  5. (now you should be able to find the Arduino in the IDE) select the COM with which the Arduino is connected.
  6. select the right board from the Arduino nano esp32 board manager
  7. select (still in the Tools tab) as programmer the Esptool (the button right above the "burn bootloader", so it is at the bottom)
  8. to download the sketch you should you the "upload using programmer" button (or just "alt + shift + "u") (it is normal that the compile time is really long)
  9. to start the program on the Arduino, just press the reset button again.

And now you get to my problem, to use the Serial monitor (or in m case the HID-protocol) you should select another COM port. But that is not really reliable. It worked for me the past few days, but since yesterday it started to disconnect automatically and kept resetting.

I hope this should work. At least it did for me. If it doesn't, just react. I will try to solve it with you.

I looked for the manual and here it is: support.arduino.cc
