1. Introduction

1.1 What is CPL03-LB LoRaWAN Pulse/Contact Sensor

The Dragino CPL03-LB is a LoRaWAN Contact Sensor for Internet of Things solution. It detects dry contact status, open time, open counts, and then upload to IoT server via LoRaWAN wireless protocol.

The CPL03-LB will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculate last open duration. User can also disable the uplink for each open/close event, instead, device can count each open event and uplink periodically.

The LoRa wireless technology used in CPL03-LB 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.

CPL03-LB supports open alarm feature, user can set open alarm for instant notice. CPL03-LB supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.

CPL03-LB is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.

CPL03-LB supports BLE configure and wireless OTA update which make user easy to use.

CPL03-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each CPL03-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

1.6 Button & LEDs

1.7 BLE connection

CPL03-LB support BLE remote configure.

BLE can be used to configure the parameter of sensor or see the console output from sensor. BLE will be only activate on below case:

• Press button to send an uplink
• Press button to active device.
• Device Power on or reset.

If there is no activity connection on BLE in 60 seconds, sensor will shut down BLE module to enter low power mode.

2. Configure CPL03-LB to connect to LoRaWAN network

2.1 How it works

The CPL03-LB 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 CPL03-LB. 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 CPL03-LB.

Each CPL03-LB 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 CPL03-LB

Press the button for 5 seconds to activate the CPL03-LB.

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 CPL03-LB to send device configure detail, include device configure status. CPL03-LB 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: https://github.com/dragino/dragino-end-node-decoder

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, CPL03-LB will store the reading for future retrieving purposes.

2.5.1 Ways to get datalog via LoRaWAN

Set PNACKMD=1, CPL03-LB will wait for ACK for every uplink, when there is no LoRaWAN network,CPL03-LB 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) CPL03-LB will do an ACK check for data records sending to make sure every data arrive server.

• b) CPL03-LB will send data in CONFIRMED Mode when PNACKMD=1, but CPL03-LB 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 CPL03-LB gets a ACK, CPL03-LB will consider there is a network connection and resend all NONE-ACK messages. 

Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

2.5.2 Unix TimeStamp

CPL03-LB 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 CPL03-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to CPL03-LB. If CPL03-LB fails to get the time from the server, CPL03-LB 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.

2.5.4 Poll sensor value

Users can poll sensor values based on timestamps. Below is the downlink command.

2.7 Frequency Plans

The CPL03-LB uses OTAA mode and below frequency plans by default. If user want to use it with different frequency plan, please refer the AT command sets.
