2. Configure TS01-LB/LS to connect to LoRaWAN network

2.1 How it works

The TS01-LB/LS is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the TS01-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

2.2 ​Quick guide to connect to LoRaWAN server (OTAA)

Following is an example for how to join the TTN v3 LoRaWAN Network. Below is the network structure; we use the LPS8v2  as a LoRaWAN gateway in this example. 

The LPS8v2 is already set to connected to TTN network , so what we need to now is configure the TTN server.

Step 1: Create a device in TTN with the OTAA keys from TS01-LB/LS.

Each TS01-LB/LS is shipped with a sticker with the default device EUI as below:


You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

Register the device




Add APP EUI in the application




Step 2: Activate on TS01-LB/LS

Press the button for 5 seconds to activate the TS01-LB/LS.

Green led will fast blink 5 times, device will enter OTA mode for 3 seconds. And then start to JOIN LoRaWAN network. Green led will solidly turn on for 5 seconds after joined in network.

After join success, it will start to upload messages to TTN and you can see the messages in the panel.

2.3 ​Uplink Payload

2.3.1 Device Status, FPORT=5

Users can use the downlink command(0x26 01) to ask TS01-LB/LS to send device configure detail, include device configure status. TS01-LB/LS will uplink a payload via FPort=5 to server.

The Payload format is as below.

2.4 Payload Decoder file

In TTN, use can add a custom payload so it shows friendly reading

In the page Applications --> Payload Formats --> Custom --> decoder to add the decoder from:

2.5 Datalog Feature

Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, TS01-LB/LS will store the reading for future retrieving purposes.

2.5.1 Ways to get datalog via LoRaWAN

There are two methods:

Method 1: IoT Server sends a downlink LoRaWAN command to poll the value for specified time range.

Method 2: Set PNACKMD=1, LHT65N will wait for ACK for every uplink, when there is no LoRaWAN network, LHT65N will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.

Set PNACKMD=1, TS01-LB/LS will wait for ACK for every uplink, when there is no LoRaWAN network,TS01-LB/LS will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.

  • a) TS01-LB/LS will do an ACK check for data records sending to make sure every data arrive server.

  • b) TS01-LB/LS will send data in CONFIRMED Mode when PNACKMD=1, but TS01-LB/LS won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if TS01-LB/LS gets a ACK, TS01-LB/LS will consider there is a network connection and resend all NONE-ACK messages. 

2.5.2 Unix TimeStamp

TS01-LB/LS uses Unix TimeStamp format based on


User can get this time from link: :

Below is the converter example


So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan -- 29 Friday 03:03:25

2.5.3 Set Device Time

There are two ways to set device's time:

1.  Through LoRaWAN MAC Command (Default settings)

User need to set SYNCMOD=1 to enable sync time via MAC command.

Once TS01-LB/LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to TS01. If TS01-LB/LS fails to get the time from the server, TS01-LB/LS will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).

Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.

2. Manually Set Time

User needs to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.

2.5.4 Poll sensor value

User can poll sensor value based on timestamps from the server. Below is the downlink command.

31Timestamp startTimestamp endUplink Interval

Timestamp start and Timestamp end use Unix TimeStamp format as mentioned above. Devices will reply with all data log during this time period, use the uplink interval.

For example, downlink command 31 5FC5F350 5FC6 0160 05 

Is to check 2020/12/1 07:40:00 to 2020/12/1 08:40:00's data

Uplink Internal =5s, means LHT65N will send one packet every 5s. range 5~255s.

2.5.5 Datalog Uplink payload (FPORT=3)

The Datalog uplinks will use below payload format.

Retrieval data payload:

Datalog payload (FPORT=3)
ValueDS18B20_temperatureRollPitchexti_flag and alarm_flagtime stamp

No ACK Message:  1: This message means this payload is fromn Uplink Message which doesn't get ACK from the server before ( for PNACKMD=1 feature)

Poll Message Flag: 1: This message is a poll message reply.

  • Poll Message Flag is set to 1.
  • Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.

For example, in US915 band, the max payload for different DR is:

a) DR0: max is 11 bytes so one entry of data

b) DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)

c) DR2: total payload includes 11 entries of data

d) DR3: total payload includes 22 entries of data.

If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0  


If TS01-LB/LS has below data inside Flash:


If user sends below downlink command:  31646D84E1646D856C05

Where : Start time: 646D84E1 = time 23/5/24 03:30:41

             Stop time: 646D856C= time 23/5/24 03:33:00

TS01x-LB will uplink this payload.

00 00 02 36 01 10 40 64 6D 84 E1 00 00 02 37 01 10 40 64 6D 84 F8 00 00 02 37 01 0F 40 64 6D 85 04 00 00 02 3A 01 0F 40 64 6D 85 18 00 00 02 3C 01 0F 40 64 6D 85 36 00 00 02 3D 01 0E 40 64 6D 85 3F 00 00 02 3F 01 0E 40 64 6D 85 60 00 00 02 40 01 0E 40 64 6D 85 6A

Where the first 11 bytes is for the first entry:

01 10 02 36 01 10 40 64 6D 84 E1




poll message flag & Alarm Flag & Level of PA8=0x40,means reply data,sampling uplink message,the PA8 is low level.

Unix time is 0x646D84E1=1684899041s=23/5/24 03:30:41

2.6 Angle Alarm Feature

TS01-LB/LS work flow with Alarm feature.

TS01-LB/LS has two alarm modes.

Alarm Mode 1:



When an angle change is detected that exceeds the range compared to the last time, an alarm is reported.

For example:



The last angle measured on the X-axis was 120 degrees, and this time the angle measured on the X-axis is 135 degrees, an alarm will be triggered to upload a data packet.

The last time the angle measured on the Y-axis was 100 degrees, but this time the angle measured on the Y-axis is 50 degrees, which will trigger an alarm and upload the data packet.

If the alarm conditions are met on the X-axis or Y-axis, an alarm will be triggered.

Alarm Mode 2:



When min=0, and max≠0, Alarm higher than max

When min≠0, and max=0, Alarm lower than min

When min≠0 and max≠0, Alarm higher than max or lower than min


AT+ XALARM=50,80      // Alarm when Roll lower than 50.


² When min=0, and max≠0, Alarm higher than max

² When min≠0, and max=0, Alarm lower than min

² When min≠0 and max≠0, Alarm higher than max or lower than min


AT+ YALARM=20,30      // Alarm when Pitch lower than 20.

Alarm Mode 0:

AT+AMOD=0             //  Turn off alarm function

Alarm time setting:

AT+ATDC=5      //   It means triggering an alarm every 5 minutes.

2.7 Calibration and installation direction

AT+CAL : Calibration angle

NOTE: If the installation direction is horizontal, the user needs to place the device horizontally for calibration. If the installation direction is vertical, the user needs to place the device vertically for calibration. If the direction is incorrect, it may result in opposite angles or inaccurate degrees.

When the calibration angle is 0 or close to 0, it is considered successful calibration.

Installation direction command:

AT+INSTAL=0        //  horizontal direction

AT+INSTAL=1      //    Vertical direction

2.8 Frequency Plans

The TS01-LB/LS uses OTAA mode and below frequency plans by default. Each frequency band use different firmware, user update the firmware to the corresponding band for their country.
