Phenomena
Reason
Solutions
1
The BLUE LED does not blink
when the battery is installed
Insert the batteries in the
wrong direction
Insert the battery in the correct
way
2
The RED LED is always on
Due to noise, the peripheral
components (i2c, spi, uart, ..)
of RF module cannot be
initialized
After the 30s the node will
automatically reset. If the noise
causes the Watchdog not to
initialize, remove the battery and
wait for more than 10 seconds,
then insert the battery again
3
The RED LED blinks
continuously (10ms ON / 2s
OFF) and the Node does not
send RF. After more than 10
sending cycles, the Node will
automatically reset
· Operating frequency in
that country is prohibited
· Operating frequency in
that country is limited to Data
rate, Tx Power
· Reconfigure the allowed
frequency of operation
· Reconfigure Data rate = DR5 /
SF07, Tx Power
4
RED LED blinks continuously
(10ms ON / 2s OFF) and Node
sends RF continuously 3s /
time but no data. After more
than 10 sending cycles, the
Node will automatically reset
Node runs dummy sending
mode
=> sent by Gateway to send
Downlink packets when users
clear Uplink and Downlink
counter values on Network
Server (build-in Gateway) when
activated by ABP
Configuration enabled by OTAA
5
The RED LED flashes 10ms
ON / 10s OFF and the Node
does not send RF
Node activation by OTAA on
the Network server has not
been successful
Using Magnet-Key to force Node to
send RF continuously for 3
seconds/time
=> when activating by OTAA
successfully, the GREEN LED will
blink after sending RF
6
The node sent RF successfully
but the GREEN LED did not
blink
LED is broken
Warranty to replace LED
7
The data packet taken from
the Gateway has an incorrect
value
The data package is encrypted
Get the decoded packet on the
Application Server
8
The node sends RF and
activates by ABP, on Gateway
receives data but Application
server has no data
The application server still
stores the counter values of the
previous Uplink and Downlink
Delete the counter values of Uplink
and Downlink on the Application
server
9
The node does not send RF
and the RF module is hot
· Insert the battery in the
opposite direction
· Short circuit
Warranty or replacement
10
Node does not send RF to
Gateway according to the
alarm, LED does not blink
· The alarm configuration is
incorrect
· Running out of the number
of alarms set for the day
· Check alarm configuration
· Check the configuration for
the maximum number of alarms
per day
11
Node does not send RF to
Gateway when activated by
the magnetic switch, LED
does not blink
The magnetic switch has
malfunctioned
Read the status of the magnetic
switch via Modbus (when powering
or attaching the battery) to see if
the magnetic switch is working.
12
Node has blinked LED GREEN
when sending RF but the
Gateway or Application server
cannot receive
· LoRa module on the
Gateway is faulty
· The IP connection (4G /
WiFi / ...) on the Gateway is
faulty
· Check Gateway's LoRa status
lights on Gateway
· Check 4G / WiFi status lights
on Gateway
