UnsupportedOperationException .

7.4.2.5. Wi-Fi Location (Wi-Fi Round Trip Time - RTT)

Device implementations:

SHOULD include support for Wi-Fi Location .

If device implementations include support for Wi-Fi Location and expose the functionality to third-

party apps, then they:

[C-1-1] MUST implement the WifiRttManager APIs as described in the SDK documentation .

[C-1-2] MUST declare the android.hardware.wifi.rtt feature flag.

[C-1-3] MUST randomize the source MAC address for each RTT burst which is executed

while the Wi-Fi interface on which the RTT is being executed is not associated with an

Access Point.

7.4.3. Bluetooth

If device implementations support Bluetooth Audio profile, they:

SHOULD support Advanced Audio Codecs and Bluetooth Audio Codecs (e.g. LDAC).

If device implementations support HFP, A2DP and AVRCP, they:

SHOULD support at least 5 total connected devices.

If device implementations declare android.hardware.vr.high_performance feature, they:

[C-1-1] MUST support Bluetooth 4.2 and Bluetooth LE Data Length Extension.

Android includes support for Bluetooth and Bluetooth Low Energy .

If device implementations include support for Bluetooth and Bluetooth Low Energy, they:

[C-2-1] MUST declare the relevant platform features ( android.hardware.bluetooth and

android.hardware.bluetooth_le respectively) and implement the platform APIs.

SHOULD implement relevant Bluetooth profiles such as A2DP, AVRCP, OBEX, HFP, etc. as

appropriate for the device.

If device implementations include support for Bluetooth Low Energy, they:

[C-3-1] MUST declare the hardware feature android.hardware.bluetooth_le .

[C-3-2] MUST enable the GATT (generic attribute profile) based Bluetooth APIs as

described in the SDK documentation and android.bluetooth .

[C-3-3] MUST report the correct value for BluetoothAdapter.isOffloadedFilteringSupported() to

indicate whether the filtering logic for the ScanFilter API classes is implemented.

[C-3-4] MUST report the correct value for BluetoothAdapter.isMultipleAdvertisementSupported() to

indicate whether Low Energy Advertising is supported.

SHOULD support offloading of the filtering logic to the bluetooth chipset when

implementing the ScanFilter API .

SHOULD support offloading of the batched scanning to the bluetooth chipset.

SHOULD support multi advertisement with at least 4 slots.
