  145. <div class="textblock"><p>Send and receive addressed, reliable, acknowledged datagrams by nRF24L01. </p>
    146. 

  146. <p>This base class provides basic functions for sending and receiving addressed, reliable, automatically acknowledged and retransmitted datagrams via nRF24L01 of arbitrary length to 32 octets per packet. Sender and receiver must each know the addreesses of the other, so arbitrary meshes and stars are not possible at this level. Directed replies (ie replies sent back to the original sender) are not possible (the address of the sender is not carried in the message). See subclasses for support for this.</p>
    147. 

  147. <p>Subclasses may use this class to implement streams, mesh routers, repeaters, translators etc.</p>
    148. 

  148. <p>On transmission, the addresses of this node defaults to 0x0000000000, unless changed by a subclass.</p>
    149. 

  149. <p>The radio is configured to use Enhanced Shockburst with retransmits. TX_ADDR and RX_ADDR_P0 are set to the transmit address (ie the address of the destination for the next message RX_ADDR_P1 is set to the address of this node RX_ADDR_P2 is set to RX_ADDR_P1 with the LSbyte set to 0xff, for use as a broadcast address</p>
    150. 

  150. <p>Naturally, for any 2 radios to communicate that must be configured to use the same frequency and data rate, and with compatible addresses </p>
