8 Troubleshooting
The following table represents some typical problems that may be encountered while
working with the Smart Object development kit, the cause of the problem and possible
solutions.
Problem
No device joins the
network (not even
Transceiver)
No SO device joins the
network, but Transceiver
does join the network
Network slow to form,
unstable after join
With multiple coexisting
networks, network slow to
form, unstable after join
Network unstable after
connecting NAMT in
Development Kit mode
NAMT in Development kit
mode slow to update after
powering off a SO
Explanation
Transceiver module
present on the P1025
Edge Router is not
connected properly to the
antenna or is not properly
inserted in the TWRPI
connector.
Net ID on the SO’s does
not match the Vendor ID
on the TWR
SO or TR on TWR with
improperly connected
antenna
Overlapping networks with
the same
NetworkID/PanID
Too aggressive
interrogation rate
Transceiver FW upgrade
from NAMT fails at start,
immediately after setting
the time from NAMT
There is no unjoin
notification; NAMT keeps
requesting COAP
resources from devices
powered off
Did not wait few minutes
after setting the time from
NAMT before connecting
to the kit again
Inconsistent COAP
resources shown after a
TWR FW upgrade
SO’s were not power
cycled after TWR FW
upgrade
Solution
Ensure that the
transceiver is properly
connected to the TWRPI
connector and the
antenna.
Ensure consistency
between SO Network ID
and TWR Vendor ID
(consistent with default
settings)
Make sure the antenna is
properly connected
The NetworkID/PanID
depends on the last byte
of Edge Router IPv6
Reduce the number of
devices or increase the
interrogation interval
(Settings -> Development
Kit Refresh interval)
Restart the Edge Router to
rebuild the resource list
Do not start the TR FW
upgrade immediately after
the TR appears in the
Network view; wait half a
minute
Restart all SO’s after TWR
FW upgrade
