11.3.2 Network Setup
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 don’t have serial access to the remote nodes (as
is the case of the two MCBs provided with the previous ETRX2 based DVKA) you will just need to
wait for them to join the network automatically. By default, once every minute, all nodes (except
coordinators) are set up to check whether there are any neighbours on the same PAN nearby, or if
they have been orphaned. If no neighbours are found after 5 consecutive tries, the unit will leave
the (deserted) PAN and try to join into a new one, once every minute.
This initial network set-up can take a few minutes, especially with no serial access to remote
nodes, but once the network is set up it will remain set even after power cycles. New nodes joining
will cause a prompt ‘NEWNODE:’ on the remote side and display the JPAN message locally as
described above.
To learn more about setting up and maintaining a PAN please refer to the user guide and the AT
Command Dictionary.

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
coordinator.
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.
