Jul 25, 2017 We will need to fill out our startScan method by configuring ScanFilter s, ScanSettings , and a ScanCallback . For now, we will not filter anything

You could use a Scan request with a ScanFilter parameter, as in this AWS CLI example: aws dynamodb scan \ --table-name Music \ --scan-filter ' { "Genre": { "AttributeValueList": [ { "S":"Rock"} ], "ComparisonOperator": "EQ" } }'. But you could use a FilterExpression instead:

Select Import an Android code sample. On the next screen select the sample Bluetooth Le Gatt under Connectivity. This project will set us up with a framework to build off of for our application. A tutorial and example of how to build an Android beacon (aka iBeacon) detector, the app that listens for signals from the emitter and triggers an action. The Real-time Communication API Blog: best practices across in-app chat, push notifications, location tracking and more. In the example, the Android app running on an Android device is the GATT client.

If a feature (for example offloaded filtering or batching) is not available natively, it will be emulated by the compat library. accessory-samples / BluetoothGattPeripheral / src / main / java / com / example / android / bluetoothgattperipheral / ClientActivity.java / Jump to Code definitions Open Android Studio and you should be greeted with the following screen.
