To configure Bluetooth Low Energy (BLE) on D-Link Access Points with iBeacon firmware, follow these steps:

1. Use a computer or mobile device to connect to the D-Link Access Point's management interface. You can typically access this interface by entering the Access Point's IP address into a web browser.

2. Enter the username and password for the Access Point's management interface. If you haven't changed the default credentials, you can find them in the Access Point's documentation or on the device itself.

3. Once logged in, navigate to the wireless or Bluetooth settings section of the management interface. The exact location of these settings may vary depending on the specific D-Link model and firmware version.

4. Look for an option to enable or activate Bluetooth Low Energy (BLE) functionality. Enable this option to turn on BLE support on the Access Point.

5. After enabling BLE, you should find settings related to iBeacon parameters. iBeacon is an Apple-specific protocol for Bluetooth devices. Configure parameters such as UUID, major, minor, and power level as per your requirements. These parameters determine how the Access Point broadcasts its BLE signals.

6. Once you've configured the BLE and iBeacon settings, save the changes in the management interface. Apply the settings, and the Access Point should begin broadcasting iBeacon signals.

7. Use a BLE-enabled device, such as a smartphone or tablet, to scan for iBeacon signals in the vicinity of the D-Link Access Point. Check that the Access Point's iBeacon signals are detectable and functioning as expected.

Please note that the specific steps and terminology may differ slightly depending on your D-Link Access Point model and firmware version. Refer to the device's documentation or consult the manufacturer's support resources for detailed instructions relevant to your specific device.
