Method Detail

onLlcpActive

public void onLlcpActive(Llcp llcp)

Description copied from interface: ServiceAccessPoint

Called if there is a device in range and the LLCP stack is active.

Specified by:

onLlcpActive in interface ServiceAccessPoint

onConnectFailed

public void onConnectFailed()

Description copied from interface: ServiceAccessPoint

Called if a connection failed/timed out.

Specified by:

onConnectFailed in interface ServiceAccessPoint

onConnectSucceeded

public void onConnectSucceeded(LlcpSocket llcpSocket)

Description copied from interface: ServiceAccessPoint

Called if a connection succeeded and the other party is ready to receive data.

Specified by:

onConnectSucceeded in interface ServiceAccessPoint

onSendFailed

public void onSendFailed()

Description copied from interface: ServiceAccessPoint

Called if a sendMessage failed.

Specified by:

onSendFailed in interface ServiceAccessPoint

onDisconnect

public void onDisconnect()

Description copied from interface: ServiceAccessPoint

Called if the other party ended the connection or the LLCP stack ended.

Specified by:

onDisconnect in interface ServiceAccessPoint

onConnectionActive

public void onConnectionActive(LlcpSocket llcpSocket)

Description copied from interface: ServiceAccessPoint

Called if this Service has an active connection. If the implementation does not invoke any method on the LlcpSocket the LLCP stack will send a Symmetry packet,

Specified by:

onConnectionActive in interface ServiceAccessPoint

onInformation

public byte[] onInformation(byte[] serviceDataUnit)

Description copied from interface: ServiceAccessPoint

Called if the other party has send a message or as a response to a send message from this implementation. If this implementation has something to respond this data has to be returned here. If the returned byte array is null the LLCP stack will answer with receive ready.

Specified by:

onInformation in interface ServiceAccessPoint

Returns:

nullable byte array as response

processMessage

protected abstract byte[] processMessage(SnepMessage snepMessage)
