Issue with NAO Board Serial Port - Driver Installation Problem

[ananda1988]

Dear Arduino Forum Community,

I hope this message finds you well. I am writing to seek assistance with a persisting issue related to the FTDI module and the NAO board's serial port on my Arduino IDE.

Problem Description: After installing the FTDI module , I encountered a problem with the NAO board's serial port. It remains grayed out and unavailable within the Arduino IDE. Strangely, the serial port works perfectly fine with my Uno board. I attempted to resolve the issue by uninstalling the FTDI driver, but unfortunately, the problem persisted. I also tried reinstalling the Arduino IDE, but Windows displayed an error stating that it couldn't install the drivers.

Additionally, an exclamation triangle mark appears next to the NAO board's entry in the Device Manager, indicating that there might be a driver issue.

Steps Taken to Resolve the Issue:

1. Uninstalled FTDI driver.
2. Reinstalled Arduino IDE.
3. Attempted driver installation on Windows (failed).

System Information:

• Arduino IDE Version: [latest]
• Operating System: [Insert Windows Version]
• Arduino Board: NAO board
  Request for Assistance: I am kindly seeking guidance from the Arduino community to resolve this issue with the NAO board's serial port. Any insights, troubleshooting steps, or recommendations would be highly appreciated.

If anyone has encountered a similar problem or knows of potential solutions, I would be grateful to receive your assistance. Please share your thoughts, suggestions, or any relevant links or resources that could help me diagnose and resolve this issue.

Thank you for your time and consideration. I look forward to your valuable input and assistance in resolving this matter.

Best regards!

Hi @ananda1988. Please tell us which USB to serial adapter chip your Nano board has. This is the largest black chip on the bottom of the board.

The chip will usually be identified by writing on the top. This might say something like "WCH CH340G" or "FTDI FT232RL".

WCH CH340

If it isn't clear, alternatively you can provide the link to where you bought the board from and we'll see if we can determine the chip from the product listing.
