Troubleshooting
The following table represents some typical problems that may be encountered while working with the Smart
Object Development Kit, the common cause of each problem, and some possible solutions.
Problem
Explanation
Solution
No device joins the network
(not even Transceiver)
The Transceiver module present on the
Edge Router is not connected properly to
the antenna.
Ensure that the Transceiver is
properly
connected
to
the
antenna.
No SO device joins the
network, but Transceiver
does join the network
The Net ID on the Smart Objects does not
match the Vendor ID on the Edge Router.
Ensure consistency between SO
Network ID and Quark Vendor ID
(consistent with default settings).
Network slow to form,
unstable after join
Smart Object or Transceiver on Edge Router
has improperly connected antenna.
Make sure the antenna is properly
connected.
With multiple coexisting
networks, network slow to
form, unstable after join
Overlapping networks with the same
NetworkID/PanID
The NetworkID/PanID depends on
the last byte of Edge Router IPv6.
Network unstable after
connecting NAMT in
Development Kit mode
Too aggressive interrogation rate
Reduce the number of devices or
increase the interrogation interval
(Settings
Development
Kit
Refresh interval).
NAMT in Development Kit
mode slow to update after
powering off a Smart Object
There is no unjoin notification; NAMT keeps
requesting COAP resources from devices
powered off.
Restart the Edge Router to rebuild
the resource list.
Transceiver FW upgrade
from NAMT fails at start,
immediately after setting
the time from NAMT
Did not wait a few minutes after setting the
time from NAMT before connecting to the
kit again.
Do not start the Transceiver
firmware upgrade immediately
after the Transceiver appears in
the Network view; wait half a
minute.
Inconsistent COAP
resources shown after an
Edge Router firmware
upgrade
Smart Objects were not power cycled after
Edge Router FW upgrade.
Restart all Smart Objects after
Edge Router FW upgrade.
NAMT refuse to connect to
Edge Router after setting
time on Edge Router
The PC time changed significantly after
setting the time on the Edge Router,
resulting in time differences between PC
and Quark, which lead to undefined
network behavior.
Power cycle the whole system
(Edge Router and Smart Objects).
