Member Functions Documentation

MbplmoError(TInt)

void

MbplmoError

(

TInt

aError

)

[pure virtual]

Notification that an error has occured. When this is called, the current subscriptions will be cancelled. If a link disconnection occurs, the CBluetoothPhysicalLinkMetrics object will no longer be valid, so it is recommended to delete the object in this callback

Parameters

TInt aError

MbplmoExtensionInterfaceL(TUid)

IMPORT_C TAny *

MbplmoExtensionInterfaceL

(

TUid

aInterface

)

[virtual]

Returns a null aObject if the extension is not implemented, or a pointer to another interface if it is.

Parameters

TUid aInterface

UID of the interface to return

MbplmoFailedContactCounterChanged(TUint16)

void

MbplmoFailedContactCounterChanged

(

TUint16

aFailedContactCounter

)

[pure virtual]

Notification for the initial failed contact counter value, and whenever the failed contact counter changes.

Parameters

TUint16 aFailedContactCounter

Number of consecutive failed contacts for this connection

MbplmoLinkQualityChanged(TUint8)

void

MbplmoLinkQualityChanged

(

TUint8

aLinkQuality

)

[pure virtual]

Notification for the initial Link Quality value and whenever the Link Quality changes.

Parameters

TUint8 aLinkQuality

Link quality for this connection where the higher value represents a better quality link

MbplmoRssiChanged(TInt8)

void

MbplmoRssiChanged

(

TInt8

aRssi

)

[pure virtual]

Notification for the initial RSSI (received signal strengh indication) value and whenever the RSSI changes

Parameters

TInt8 aRssi

Current RSSI Value in dB

MbplmoTransmitPowerLevelChanged(TInt8)

void

MbplmoTransmitPowerLevelChanged

(

TInt8

aTransmitPowerLevel

)

[pure virtual]

Notification for the initial transmit power level, and whenever the transmit power level changes.

Parameters
