Description

Warning: DoStartLeDiscovery is deprecated. Please use DoStartDiscovery.

Note: This is an abstract method that platform-specific subclasses of TBluetoothLEAdapter implement.

Starts a discovery operation to find remote devices using Bluetooth Low Energy.

StartDiscovery calls DoStartLeDiscovery.

DoStartLeDiscovery accepts the following parameters:

• Timeout: How much time you want to spend discovering remote devices using Bluetooth Low Energy.
• AFilterUUIDList (Optional): A list of one or more Bluetooth UUIDs.

When the discovery operation finishes, your adapter calls DoDiscoveryEnd providing a list of discovered remote devices.

DoStartLeDiscovery returns True if the discovery starts successfully, or False if something prevents the discovery from starting.

Platform Support

Platform	Notes
32-bit Windows 64-bit Windows	Timeout is ignored because DoStartLeDiscovery calls DoDiscoveryLEEnd immediately. Always returns True.
Mac OS X	OnDiscoveryEnd always occurs some time after the specified Timeout, never before. Always returns True.
iOS	OnDiscoveryEnd always occurs some time after the specified Timeout, never before. Always returns True.
Android	OnDiscoveryEnd always occurs after the specified Timeout, never before.
