Communication Protocol
The 433 MHz RF Transceivers do not have a built-in protocol and therefore are not immune to noise and
errors in the signal. To account for this it is recommended that you initiate error checking on your
microcontroller to be sure the packets are valid. You could even create a simple protocol that could be
used to verify each transmission arrives at its destination intact. For error checking examples please see
the code example downloads on the product page of our website, www.parallax.com. You can find this
