Sending and receiving data

Now that the XBee connectivity is covered, it is time to actually exchange some data wirelessly between your Arduinos. In the previous chapter, you have already seen the API frames involved in transmitting and receiving data through the network. In this section, you will let the Arduino use those API frames to exchange a simple Hello, world! message again. For this, the sender will use the XBee module that you configured as a router, while the receiver will use the coordinator XBee.

Sending data

Remember that sending a message involves a few different API frames:

  • The sender sends a ZigBee Transmit Request API frame to the XBee module, containing the destination address and the message.
  • The receiver receives a ZigBee Receive Packet API frame, containing the sender address and the message. The receiver XBee will also (automatically) send an acknowledgement (ack) back to the sender so the sender knows the transmission was successful.
  • The sender receives a ZigBee Transmit...
