How to Change Advertise Period to Some Seconds by Lib AltBeacon or by Native Instruments in Android?

Using Lib AltBeacon

Lib AltBeacon is a popular Android library for working with beacons. It provides a simple and intuitive API for configuring and interacting with beacons. To change the advertise period using Lib AltBeacon, follow these steps:

1. First, add the Lib AltBeacon library to your Android project. You can do this by adding the following dependency to your build.gradle file:

dependencies {
implementation 'org.altbeacon:android-beacon-library:[version]'
}

2. Next, create an instance of the BeaconTransmitter class and set the advertise period using the setAdvertisePeriod() method:

    BeaconTransmitter beaconTransmitter = new BeaconTransmitter(this, adapter);
    beaconTransmitter.setAdvertisePeriod(500); // Set advertise period to 500ms
  

3. In the above code, this refers to the current context, and adapter is an instance of the BluetoothAdapter class.
4. Finally, start the beacon transmission using the startAdvertising() method:

    beaconTransmitter.startAdvertising();
  

Using Native Android Instruments

If you prefer not to use a third-party library, you can modify the advertise period using native Android instruments. This approach requires working with the Android Bluetooth Low Energy (BLE) API. Here’s how to do it:

Step 1: Create a BluetoothAdapter Instance

To interact with the BLE adapter, you need to create an instance of the BluetoothAdapter class:

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

Step 2: Create a BluetoothLeAdvertiser Instance

Next, create an instance of the BluetoothLeAdvertiser class, which is responsible for advertising the beacon’s identifier:

BluetoothLeAdvertiser bluetoothLeAdvertiser = bluetoothAdapter.getBluetoothLeAdvertiser();

Step 3: Set the Advertise Period

To set the advertise period, you need to create an instance of the AdvertiseSettings class and set the txPower and advertiseMode properties:

AdvertiseSettings advertiseSettings = new AdvertiseSettings.Builder()
    .setAdvertiseMode(AdvertiseSettings.ADVERTISE_MODE_LOW_LATENCY)
    .setTxPowerLevel(AdvertiseSettings.ADVERTISE_TX_POWER_HIGH)
    .setConnectable(true)
    .setTimeout(1000)
    .build();

In the above code, we’re setting the advertise mode to low latency, transmission power to high, and enabling connectivity. You can adjust these settings according to your requirements.

Step 4: Create an AdvertiseData Instance

Create an instance of the AdvertiseData class, which represents the data to be advertised:

AdvertiseData advertiseData = new AdvertiseData.Builder()
    .addServiceUuid ParcelUuid.fromString("0000abcd-0000-1000-8000-00805f9b34fb"))
    .setIncludeDeviceName(true)
    .build();

In the above code, we’re adding a service UUID and enabling device name inclusion. You can customize the advertise data according to your needs.

Step 5: Start Advertising

Finally, start the advertising process using the startAdvertising() method:

bluetoothLeAdvertiser.startAdvertising(advertiseSettings, advertiseData, advertisementCallback);

In the above code, advertisementCallback is an instance of the AdvertiseCallback class, which provides callbacks for advertising events.

Conclusion

In this comprehensive guide, we’ve covered the steps to modify the advertise period using both Lib AltBeacon and native Android instruments. By adjusting the advertise period, you can optimize the performance and power consumption of your beacon-based Android application. Remember to consider the implications of modifying the advertise period on your specific use case and adjust the settings accordingly. Happy coding!
