int wifi_direct_start_discovery ( bool  listen_only,
int  timeout 
)

Starts discovery to find all P2P capable devices, asynchronously.

If application developers call wifi_direct_start_discovery() with listen_only as true, then skip the initial 802.11 Scan and then enter Listen state instead of cycling between Scan and Listen.

Since :
2.3
Privilege Level:
public
Privilege:
http://tizen.org/privilege/wifidirect
Remarks:
The function can be called if the Wi-Fi Direct state is one of:
WIFI_DIRECT_STATE_ACTIVATED
WIFI_DIRECT_STATE_DISCOVERING
WIFI_DIRECT_STATE_GROUP_OWNER
The function can be called even if there is another discovery in progress. All started processes will run simultaneously. Each process will receive WIFI_DIRECT_DISCOVERY_FINISHED event in wifi_direct_discovery_state_chagned_cb().
Parameters:
[in]listen_onlyThe status of listen only: (true = listen only, false = cycling between Scan and Listen)
[in]timeoutSpecifies the duration of discovery period, in seconds. If 0, then there is no limit on how long the discovery takes. The actual limit (and time after which discovery stops) depends on the vendor's hardware and firmware
Returns:
0 on success, otherwise a negative error value
Return values:
WIFI_DIRECT_ERROR_NONESuccessful
WIFI_DIRECT_ERROR_INVALID_PARAMETERInvalid parameter
WIFI_DIRECT_ERROR_OPERATION_FAILEDOperation failed
WIFI_DIRECT_ERROR_COMMUNICATION_FAILEDCommunication failed
WIFI_DIRECT_ERROR_PERMISSION_DENIEDPermission denied

WIFI_DIRECT_ERROR_NOT_SUPPORTEDNot supported
WIFI_DIRECT_ERROR_NOT_INITIALIZEDNot initialized
WIFI_DIRECT_ERROR_RESOURCE_BUSYDevice or resource busy
Precondition:

int wifi_direct_start_discovery_specific_channel ( bool  listen_only,

Starts discovery to find all P2P capable devices with specified channel, asynchronously.

If you call this function with channel as WIFI_DIRECT_DISCOVERY_FULL_SCAN it works same as wifi_direct_start_discovery() API. If application developers call this function with channel as WIFI_DIRECT_DISCOVERY_SOCIAL_CHANNEL, then will search only the devices on the social channels(channel 1 or 6 or 11). If application developers call this function with channel as WIFI_DIRECT_DISCOVERY_CHANNEL1, then will search only the devices on the channel 1. If application developers call this function with channel as WIFI_DIRECT_DISCOVERY_CHANNEL6, then will search only the devices on the channel 6. If application developers call this function with channel as WIFI_DIRECT_DISCOVERY_CHANNEL11, then will search only the devices on the channel 11.
