BaySerialRF24.h

/*
 * This is an alternativ for sending BayEOS-Frames over RF24 using the BaySerial protocol
 *
 * BaySerial layer is on top of RF24
 * We have additional checksum and no limitation to 32 byte as for simple RF24
 * The receiver sends a acknowlege to the sender via RF24. This is done by the
 *
 * The frames look like this:
 * [NR][ --- DATA ----]
 *
 * NR incremented to avoid duplicated RF24-RX
 * DATA of new frames are copied to the buffer
