Troubleshooting for Sigfox Communication

This is the troubleshooting for Sigfox communication of Sigfox-ready sensors with FW versions listed below:

No.

Phenomena

Reason

Solutions

1

Node does not send RF to the base station periodically, LED does not blink

No power supply or battery ran out

The configuration sending cycle is incorrect

Check that each battery is empty OR not installed correctly

Check the power supply

Check the send cycle configuration

2

Node does not send RF to the base station according to the alarm, LED does not blink

The alarm threshold values are incorrect and/or disabled alarm function

Running out of the number of alarms set for the day

Check alarm threshold values and alarm enable

Check the configuration for the maximum number of alarms per day

3

Node does not send RF to the base station when activated by the magnetic switch, LED does not blink

The magnetic switch has malfunctioned

Or place the Magnet key in not right position

Locate the correct position for the magnet key

Read the status of the magnetic switch via Modbus (when powering or attaching the battery) to see if the magnetic switch is working.

4

Node has blinked LED when sending RF but the base station cannot receive

Out of the number of RF packages of uplink per day (max 140 packages/day)

Check on the base station whether the event message exceeds the number of RF packets

5

Node has sent RF but the LED does not blink

LED malfunction

Contact manufacturer

6

The node does not send RF and the RF module is hot

Insert the battery in the wrong direction

Electronics got problem

Check battery polarity

7

RSSI is weak and often loses data

Distance between Node and Base station is far or there are many obstructions

Connection to Antenna problem

Check the location of the Sigfox node and distance to the base station

Check the antenna connector in the PCB

8

The measurement values from the sensor do not change and keep constant values for a long time

Sensor got failure

Sensor cable broken

The sensor connector is not connected firmly

Check sensor cable and connector

If the issue still exists, please contact the manufacturer for a warranty or replace the new sensor
