Table 1—The various packets contain different information. Each packet broadcast over a wireless radio begins with data describing the sender. The HIGH and LOW bits of each number were used because larger 16-bit numbers had to be broken up into two smaller 8-bit numbers in order to be sent using the ZigBee radios.
