XMODEM is generally used when bootloading a new firmware file on to a module.
12.3 A Quick Start
This section gives you a quick introduction on how to get started. Power up the node connected to
the PC and open a connection to the correct device; refresh the list of COM ports if the expected
device is not shown. Type
AT
followed by
<enter>
. If the communication to the module is working
the module will prompt
OK
, if not check the USB connectivity and driver status and make sure you
have connected to the correct COM port with the correct speed. Please note that even when
connected to the wrong COM port there may be a reply to AT, for example when you are
communicating with your PC
’s modem or Bluetooth device. To double check you are actually
communicating with a Telegesis ZigBee device use the ATI command described below.
Select the correct set of buttons
Type
ATI<enter>
to verify your firmware version (eg R308C). Then select File
Open Layout on
the menu bar and open the appropriate xml file
– usually R3xx.xml. This attaches the correct set of
AT commands to the buttons. You can create your own button configurations for different situations
and save them as separate files. Telegesis Terminal starts up using the configuration of the previous
session.
Network Setup
Figure 19. Command Line Interactions
To establish a PAN network issue the
AT+EN
command, or alternatively
press the ‘
Establish PAN
’ button.
The local unit will now scan all
available 16 channels and establish a
PAN with a random PAN ID, on the
quietest available one. This may take
up to 16 seconds and leads to the
node
becoming
the
network
’s
coordinator. When successful the
module will prompt ‘
JPAN
’
followed by
the details of the newly created PAN.
If you get an error message instead, it
is likely that the module was already
part of a PAN, so you will need to
issue the
AT+DASSL
command or
press the ‘
Disas Local
’ button to
leave the PAN before going back to
starting a new one. In order to find out
about the network status simply issue
the
AT+N
command or press the
‘
NWK Info
’ button.
Once the network is established, remote nodes can be powered up ready to join in. If you have
serial access to remote nodes simply issue the
AT+JN
command or press the ‘
Join any PAN
’ button,
to join the newly established PAN. If you do not have serial access to the remote nodes (as is the
