sendLZ4Message()

void FASTRUN SvcSerialCommandInterface::sendLZ4Message

(

)

Calling this function signals the end of a compressed message.
The txBuffer contents are lz4 compressed, base64 encoded and finally sent.
The serial message format is "LZ4 [UNCOMPRESSED_SIZE] [BASE64 encoded LZ4 compressed message]".
