Constructor Detail

BrickPiSerialTransmitter

public BrickPiSerialTransmitter(int timeout)

Construct the BrickPiSerialTransmitter with blocking queues for messaging

Parameters:

timeout - The timeout in millisecond to wait before retrying to send and receive data

Throws:

RaspoidSerialException - in case of trouble when opening serial communications with the brick pi

Method Detail

sendMessage

public java.util.Map.Entry<Atmel,byte[]> sendMessage(java.util.Map.Entry<Atmel,byte[]> bytesChunkToSend)

Send a message to the BrickPi then waits for the reponse message

Parameters:

bytesChunkToWrite - the bytes of the message to write

Returns:

an entry with the response message and the Atmel it came from
