[C-1-3] MUST implement the multicast API as described in the SDK documentation.

[C-1-4] MUST support multicast DNS (mDNS) and MUST NOT filter mDNS packets

(224.0.0.251) at any time of operation including:

Even when the screen is not in an active state.

For Android Television device implementations, even when in standby power

states.

[C-1-5] MUST NOT treat the WifiManager.enableNetwork() API method call as a sufficient

indication to switch the currently active Network that is used by default for application

traffic and is returned by ConnectivityManager API methods such as getActiveNetwork and

registerDefaultNetworkCallback . In other words, they MAY only disable the Internet access

provided by any other network provider (e.g. mobile data) if they successfully validate that

the Wi-Fi network is providing Internet access.

[C-1-6] MUST, when the ConnectivityManager.reportNetworkConnectivity() API method is called,

re-evaluate the Internet access on the Network and, once the evaluation determines that

the current Network no longer provides Internet access, switch to any other available

network (e.g. mobile data) that provides Internet access.

[C-SR] Are STRONGLY RECOMMENDED to randomize the source MAC address and

sequence number of probe request frames, once at the beginning of each scan, while STA

is disconnected.

Each group of probe request frames comprising one scan should use one

consistent MAC address (SHOULD NOT randomize MAC address halfway

through a scan).

Probe request sequence number should iterate as normal (sequentially)

between the probe requests in a scan.

Probe request sequence number should randomize between the last probe

request of a scan and the first probe request of the next scan.

[C-SR] Are STRONGLY RECOMMENDED, while STA is disconnected, to allow only the

following elements in probe request frames:

SSID Parameter Set (0)

DS Parameter Set (3)

If device implementations support Wi-Fi and use Wi-Fi for location scanning, they:

[C-2-1] MUST provide a user affordance to enable/disable the value read through the

WifiManager.isScanAlwaysAvailable API method.

7.4.2.1. Wi-Fi Direct

Device implementations:

SHOULD include support for Wi-Fi Direct (Wi-Fi peer-to-peer).

If device implementations include support for Wi-Fi Direct, they:

[C-1-1] MUST implement the corresponding Android API as described in the SDK

documentation.

[C-1-2] MUST report the hardware feature android.hardware.wifi.direct .

[C-1-3] MUST support regular Wi-Fi operation.

[C-1-4] MUST support Wi-Fi and Wi-Fi Direct operations concurrently.

7.4.2.2. Wi-Fi Tunneled Direct Link Setup
