2. Configure DS03A-LB/LS to connect to LoRaWAN network

2.1 How it works

The DS03A-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 DS03A-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 2 hours.

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 DS03A-LB/LS.

Each DS03A-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 and DEV EUI

Add APP EUI in the application

Add APP KEY

Step 2: Activate on DS03A-LB/LS

Press the button for 5 seconds to activate the DS03A-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

Include device configure status. Once DS03A-LB/LS Joined the network, it will uplink this message to the server. After that, DS03A-LB/LS will uplink Device Status every 12 hours.

Users can also use the downlink command(0x26 01) to ask DS03A-LB/LS to resend this uplink. This uplink payload also includes the DeviceTimeReq to get time.

The Payload format is as below.

Example parse in TTNv3

Sensor Model: For DS03A-LB/LS, this value is 0x1B

2.3.2  Sensor Configuration, FPORT=4

DS03A-LB/LS will only send this command after getting the downlink command (0x26 02) from the server.

Example parse in TTNv3

• TDC: (default: 0x001C20)

Uplink interval for the Open/Close Event, default value is 0x001C20 which is 7200 seconds = 2 hours.

• Disalarm: (default: 0)

 If Disalarm = 1, DS03A-LB/LS will only send uplink at every TDC periodically. This is normally use for pulse meter application, in this application, there are many open/close event, and platform only care about the total number of pulse.

 If Disalarm = 0, DS03A-LB/LS will send uplink at every TDC periodically and send data on each open/close event. This is useful for the application user need to monitor the open/close event in real-time.

 Note: When Disalarm=0, a high frequently open/close event will cause lots of uplink and drain battery very fast. 

• Keep Status1 & Keep Time1 & Keep Status2 & Keep Time2

Shows the configure value of Alarm Base on Timeout Feature

• Alarm interval(default: 0)

When the state of the door sensor has not been changed after the timeout alarm, the device will send a uplink every alarm interval. It will stop the alarm until the state of the door sensor is changed after the timeout alarm.

2.3.3  Real-Time Open/Close Status, Uplink FPORT=2

DS03A-LB/LS will send this uplink after Device Status once join the LoRaWAN network successfully. And DS03A-LB/LS will send uplinks when:

• Every 2 hours, this interval can be changed.
• There is an Open/Close event.  (This info can be disabled by AT+DISALARM=1)

1) When AT+TTRCHANNEL=1, Uplink Payload totals 11 bytes. (Default mode)

Status & Alarm:

• Count mod:Default=0

0: Uplink total open door times since factory

1: Uplink total open door times since last FPORT=2 uplink. 

• TDC flag

When the flag is 1, it means sending packets at normal time intervals.

Otherwise, it is a packet sent at non-TDC time. 

• Alarm

See Alarm Base on Timeout

• Status

This bit is 1 when the door sensor is open and 0 when it is close. 

• Total open door events

Total pulse/counting base on open door.

Range (3 Bytes) : 0x000000 ~ 0xFFFFFF . Max: 16777215

• The last door open duration

Door sensor last open duration.

Unit: sec.

2) When AT+TTRCHANNEL=2, Uplink Payload totals 18 bytes.

(When the maximum DR of some frequencies is 11 bytes, it will cause the server to receive empty packets)

Note:When using the AT+TTRCHANNEL=2 command, the Datalog function cannot be used.

Status1 & Alarm1:

Status2 & Alarm2:

• Count mod:Default=0

0: Uplink total open door times since factory

1: Uplink total open door times since last FPORT=2 uplink. 

• TDC flag

When the flag is 1, it means sending packets at normal time intervals.

Otherwise, it is a packet sent at non-TDC time. 

• Alarm1 or Alarm2

See Alarm Base on Timeout

• Status1 or Status2

This bit is 1 when the door sensor is open and 0 when it is close. 

• Total open door events1 or Total open door events2

Total pulse/counting base on open door.

Range (3 Bytes) : 0x000000 ~ 0xFFFFFF . Max: 16777215

• The last door open duration1 or The last door open duration2

Door sensor last open duration.

Unit: sec.

2.3.4  Historical Door Open/Close Event, FPORT=3

DS03A-LB/LS stores sensor values and users can retrieve these history values via the downlink command.

The historical payload includes one or multiplies entries and every entry has the same payload as Real-Time open/close status.

Status & Alarm:

• Each data entry is 11 bytes and has the same structure as Real-Time open/close status, to save airtime and battery, DS03A-LB/LS will send max bytes according to the current DR and Frequency bands.

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

If DS03A-LB doesn't have any data in the polling time. It will uplink 11 bytes of 0

Downlink:

2.4 Payload Decoder file

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, DS03A-LB/LS will store the reading for future retrieving purposes.

Note:After the device is reset,in cumulative counting mode,the last stored count value will be read as the initial value.

2.5.1 Ways to get datalog via LoRaWAN

Set PNACKMD=1, DS03A-LB/LS will wait for ACK for every uplink, when there is no LoRaWAN network, DS03A-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) DS03A-LB/LS will do an ACK check for data records sending to make sure every data arrive server.
• b) DS03A-LB/LS will send data in CONFIRMED Mode when PNACKMD=1, but DS03A-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 DS03A-LB/LS gets a ACK, DS03A-LB/LS will consider there is a network connection and resend all NONE-ACK Message. 

2.5.2 Unix TimeStamp

DS03A-LB/LS uses Unix TimeStamp format based on

User can get this time from link:  https://www.epochconverter.com/ :

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

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

Once DS03A-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 DS03A-LB/LS. If DS03A-LB/LS fails to get the time from the server, DS03A-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 and loriot support but TTN 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 v2 if SYNCMOD=1.

2.6 ​Show Data in DataCake IoT Server

Datacake IoT platform provides a human-friendly interface to show the sensor data, once we have sensor data in TTN V3, we can use Datacake to connect to TTN V3 and see the data in Datacake. Below are the steps:

Step 1: Link TTNv3 to Datacake.https://docs.datacake.de/lorawan/lns/thethingsindustries#create-integration-on-tti

Step 2: Configure DS03A-LB/LS in Datacake.

2.7 Frequency Plans

The DS03A-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.
