Once Send has been clicked and you see the confirmation of the packet actually sent in hexadecimal form, click Check to
see if you have received a reply yet. The reply will be displayed as illustrated below when received.
When a device is in sleep mode, it is important to note that your Send will not be received until the end of the device’s
sleep period. As first shipped, devices are often not configured to sleep. But once configured, you will have to wait a
while for your response. While it may seem inconvenient, the longer you have to wait for each response, the longer your
battery life is going to be since you now know the sleep period is long.
The reply received in response to the above command is illustrated below. The first several bytes are confirmation of the
address of the device. The last three bytes are of interest. They should be the 2-character AT command followed by a
status byte. A status byte of ‘00’ means the command was executed ok. A nonzero value means something was wrong,
such as invalid parameter, invalid command, etc.
This short example is simply an overview of seeing a ZigBee device come online for the first time. The /NI command is
an example of only one of several commands you will need to send to a typical sensor before it is fully configured. More
discussion about configuration is yet to come.
