# Hardware ID

Pro Feature

This is an exclusive feature of WebSerial Pro. Check it out here.

## Introduction​

The Hardware ID feature is shown on the WebSerial Pro portal for easy identification of multiple devices in your network. This ID should be a unique string that helps you easily identify the specific hardware device among others in your network.

### Example Usage:​

    ...
    #include <WebSerialPro.h>

    void setup() {
      ...

      // Set the Hardware ID
      WebSerial.setID("my_device_001");
    }

    void loop() {
      ...
    }

In the above example, the `WebSerial.setID("my_device_001");` function call assigns the Hardware ID "my_device_001" to the device.

## Best Practices​

To make the most of the Hardware ID feature, consider the following best practices:

- Choose a Hardware ID that is unique to each device to avoid conflicts.

- Avoid using special characters or spaces in the Hardware ID, as these might cause issues when used in network communication or file naming.

- Document and keep track of the Hardware IDs for all your devices to ensure proper management.

- Ensure that the Hardware ID is set during the device's initialization phase, such as in the `setup()` function, to guarantee that it is properly configured before any network or communication activities.
