Description
Adapter to connect applications over Classic Bluetooth.
Prerequisites
To use TTetheringBluetoothAdapter:
- Before trying to connect two applications using Classic Bluetooth, ensure to pair the two devices on the system level.
- To run your application in an Android device, you need to enable the required Uses Permissions. Set Bluetooth and Bluetooth Admin values to
True.
Target Syntax
TTetheringBluetoothAdapter supports the following syntax for the ATarget parameter of TTetheringManager.DiscoverManagers:
- A Bluetooth device name.
- A Bluetooth MAC address.
- An empty string, to target paired devices.
Reducing Discovery Timeout
To reduce the time that it takes to discover Bluetooth managers, unpair any paired device of the global Bluetooth manager that is not connected. To unpair a device, use the UnPair method of the Bluetooth adapter of the global Bluetooth manager.
Limitations
There are 30 available Classic Bluetooth physical channels. You can only have up to 7 instances of TTetheringBluetoothAdapter on the same device at once, since a Classic Bluetooth application with a TBluetoothManager and a Bluetooth profile uses 4 of these channels.
