Bluetooth support in XE7
• RTL new unit: System.Bluetooth, System::Bluetooth
• Multi-device API for Classic Bluetooth & Bluetooth LE
• TBluetoothLE component
• Classic Bluetooth classes
– TBluetoothManager
– TBluetoothAdapter
– TBluetoothDevice

Bluetooth and App Tethering
• To implement Classic Bluetooth support in your VCL
and FMX apps:
– Obtain an instance of TBluetoothManager.
– Discover remote devices and pair with them.
– Connect to the paired devices.
– Exchange data with the connected devices.

BluetoothLE and Devices
• Use an instance of TBluetoothLEDevice to:
– Discover services that the remote device provides
– Obtain detailed info including the characteristics
• Read and Write a characteristic value
• Ask to be notified of changes in a Characteristic value
– SetCharacteristicNotification method
– OnCharacteristicRead event handler
• Get the received signal strength indicator (RSSI)
• To obtain an instance of TBluetoothLEDevice
– Use the StartDiscovery method or LastDiscoveredDevices property

BluetoothLE GATT-based Profile Hierarchy
• Generic Attribute Profile (GATT)
– Services are collections of characteristics
and relationships to other services that
encapsulate the behavior of part of a
device
– https://developer.bluetooth.org/gatt/Pages
/GATT-Specification-Documents.aspx
• If device is not GATT
– Try using discovery
– Contact the device manufacturer
