The LoRa wireless technology used in DS03A-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

)))

(((

The DS03A-LB/LS will send periodically data every 2 hours as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. Users can also disable the uplink for each open/close event, instead, DS03A-LB/LS can count each open event and uplink periodically.

)))

(((

DS03A-LB/LS supports (% style="color:blue" %)**Datalog Feature,**(%%) it can save the data when there is no LoRaWAN network and uplink when network recover.

190

The DS03A-LB/LS is configured as (% style="color:#037691" %)**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.

)))

== 2.5 Datalog Feature ==

667

668

669

(% style="color:blue" %)**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.

670

671

(% style="color:red" %)**Note:After the device is reset,in cumulative counting mode,the last stored count value will be read as the initial value.**

672

673

674

=== 2.5.1 Ways to get datalog via LoRaWAN ===

675

676

677

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.

678

679

* a) DS03A-LB/LS will do an ACK check for data records sending to make sure every data arrive server.

680

* 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.

681

682

=== 2.5.2 Unix TimeStamp ===

683

684

685

DS03A-LB/LS uses Unix TimeStamp format based on

686

687

[[image:image-20250331163638-7.jpeg]]

688

689

User can get this time from link: [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :

690

691

Below is the converter example

692

693

[[image:image-20250331163648-8.jpeg]]

694

695

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

696

697

698

=== 2.5.3 Set Device Time ===

699

700

701

User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.

702

703

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).

704

705

(% style="color:red" %)**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.**

711

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:

712

713

714

(% style="color:blue" %)**Step 1:**(%%)** Link TTNv3 to Datacake.**[[https:~~/~~/docs.datacake.de/lorawan/lns/thethingsindustries#create-integration-on-tti>>url:https://docs.datacake.de/lorawan/lns/thethingsindustries#create-integration-on-tti]]
