Hardware ID

The hardware ID is displayed at the bottom of the WebSerial Pro terminal. It helps you identify a specific device when several devices on your network run WebSerial Pro.

Set the hardware IDCopy Anchor Link

Call setID() in setup():

WebSerial.setID("my_device_001");

If you do not set an ID before calling begin(), WebSerial Pro generates one from the chip ID:

ExampleCopy Anchor Link

#include <WebSerialPro.h>

// ...

void setup() {
  // ...

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

  WebSerial.begin(&server);
  server.begin();
}

void loop() {
  // ...
  WebSerial.loop();
}

Best practicesCopy Anchor Link

• Use an ID that is unique for each device.
• Avoid special characters and spaces, which can cause problems in network communication or file names.
• Keep a record of the IDs assigned to your devices.
• Set the ID during initialization, in setup(), before any network communication takes place.
