Trouble Shooting
Sensor Node not join the network, how to do?
1.
Check the gateway channels configuration. Make sure the gateway and Sensor Node have the same uplink and
downlink channels.
2.
Check the gateway real-time log and RESET the sensor to see if there are any sensor data packets. If there are
packets, check whether the gateway is sending downlink packets.
3.
If the channels and other configurations are correct and the gateway logs do not have packets, please contact
technical support.
Why is the new sensor’s battery not 100%?
Battery power detection is not high-precision. Its principle is to measure the supply voltage, when the power is
turned on and repeatedly RESET, the voltage is unstable, so it is not 100%. When the sensor is stable, the power will
be more accurate.
Why can't I get into configuration mode with the USB to
TTL serial tool?
1.
Make sure the RX/TX/GND connection is correct.
2.
Keep the pins in close contact during communication.
3.
Operation of sensor entering configuration mode: Turn on the switch, long press SET, and press RESET at the
same time.
