2. Operation Mode
2.1 How to activateWTS?
The WTS has two working modes:
 Deep Sleep Mode: WTSdoesn’t have any LoRaWAN activate. This mode is used for storage
and shipping to save battery life.
 Working Mode: In this mode, WTS will work as LoRaWAN Sensor to Join LoRaWAN network
and send out sensor data to server. Between each sampling/transmit periodically, WTS will
be in STOP mode
(IDLE mode), in STOP mode, WTS has the same power consumption as
Deep Sleep mode.
The WTS is set in deep sleep mode by default; The ACT button on the top of device is used to
switch to different modes:
Behavior on ACT Function Action
Pressing ACT
between 1s < time
< 3s
Test uplink
status
If WTS is already Joined to LoRaWAN network, WTS will
send an uplink packet.
Pressing ACT for
more than 3s
Active Device green led will fast blink 5 times, device will enter working
mode and start to JOIN LoRaWAN network. green led will
solidly turn on for 5 seconds after joined in network.
Fast press ACT 5
times.
Deactivate
Device
red led will solid on for 5 seconds. Means WTS are in
Deep Sleep Mode.
2.2 How it works?
The WTS is configured as LoRaWAN OTAA Class A mode by default. Each WTS is shipped with a
worldwide unique set of OTAA and ABP keys. To use WTS in a LoRaWAN network, user needs to
input the OTAA keys in the network server. So WTS can join the LoRaWAN network and start to
transmit sensor data. The default period for each uplink is 20 minutes.
2.3 Example to join LoRaWAN network
This section shows an example for how to join the TTN V3 LoRaWAN IoT server. Use with other
LoRaWAN IoT server is of similar procedure.
