2. How to use

2.1 How it works?

Each WSC2-Compact-LS is shipped with a worldwide unique set of OTAA keys. To use WSC2-Compact-LS in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After finish installation as above. Create WSC2-Compact-LS in your LoRaWAN server and Power on WSC2-Compact-LS , it can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is 20 minutes.

2.2 Example to use for LoRaWAN network(OTAA)

This section shows an example for how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are of similar procedure.

Assume the DLOS8N is already set to connect to TTN V3 network . We need to add the WSC2-Compact-LS device in TTN V3:

Step 1: Create a device in TTN V3 with the OTAA keys from WSC2-Compact-LS.

Each WSC2-Compact-LS is shipped with a sticker with the default device EUI as below:

User can enter these keys in the LoRaWAN Server portal. Below is TTN V3 screen shot:

Create the application.

Add devices to the created Application.

Enter end device specifics manually.

Add DevEUI and AppKey. Customize a platform ID for the device.

Step 2: Add decoder

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

Click this link to get the decoder: https://github.com/dragino/dragino-end-node-decoder/tree/main/

Below is TTN screen shot:

Step 3: Activate on WSC2-Compact-LS

Press the button for 5 seconds to activate the WSC2-Compact-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

Uplink payloads include two types: Valid Sensor Value and other status / control command.

• Valid Sensor Value: Use FPORT=2
• Other control command: Use FPORT other than 2.

2.3.1 Uplink FPORT=5, Device Status

Temperature

Example:

If payload is: 0105H: (0105 & 8000 == 0), temp = 0105H /10 = 26.1 degree

If payload is: FF3FH : (FF3F & 8000 == 1) , temp = (FF3FH - 65536)/10 = -19.3 degrees.

Starting from firmware version 1.0.6, the WSC2-Compact-LS adds support for:

• One wind speed sensor
• Two soil sensor
• One TSR (Total Solar Radiation) sensor
• One PAR (Photosynthetically Active Radiation) sensor

**Note on Soil Sensors: **The WSC2-Compact-LS can only recognize soil sensors with addresses 01 and 02. When using two soil sensors simultaneously, they must be configured with different addresses (one must be 01 and the other 02).

After enabling the corresponding sensor data readings using the AT+WSS command based on actual requirements, the device supports a new uplink format on FPORT=2 to report real-time values from these sensors.

**Configuration Commands & Wiring Method: **Refer to section 3.4.7 for detailed wiring instructions and command usage.

Example:

AT+WSS=1,1,1,1,1 enables all available sensors (default is AT+WSS=0,0,0,0,0).

2.4 Unix TimeStamp

WSC2-Compact-LS uses Unix TimeStamp format based on

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

Below is the converter example

So, we can use AT+TIMESTAMP=1742278702 or downlink 3067D9102E to set current time : March 18, 2025 06:18:22

2.5 Set Device Time

There are two ways to set the device's time:

1. Through LoRaWAN MAC Command (Default settings)

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

Once WSC2-Compact-LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and server will reply with (DeviceTimeAns) to send the current time to WSC2-Compact-LS. If WSC2-Compact-LS fails to get the time from server, WSC2-Compact-LS will use the internal time and wait for next time request (AT+SYNCTDC to set time request period, default is 10 days).

Note: LoRaWAN Server needs 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. Manually Set Time

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

2.6 Frequency Plans

The WSC2-Compact-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.

/docs/wiki/Configuration/end-node/frequency-band/

3. Configure WSC2-Compact-LS

3.1 Configure Methods

WSC2-Compact-LS supports below configure method:

• LoRaWAN Downlink. Instruction for different platforms: See IoT LoRaWAN Server section.

3.2 Serial Access Password

After the Bluetooth or UART connection is successful, use the Serial Access Password to enter the AT command window.

The label on the box of the node will print the initial password: AT+PIN=xxxxxx, and directly use the six-digit password to access the AT instruction window.

If you need to change the password, use AT+PWORD=xxxxxx (6 characters)

Note: After entering the command, you need to add a line break, and you can also set automatic line breaks in the Bluetooth tool or UART connection tool.

3.3 General Commands

These commands are to configure:

4.2 Solar charging instructions

Battery capacity 3000mAh, maximum charging power of solar panel: 0.9W, charging efficiency: 22 Normally it takes 56 hours of charging to fill the battery when the sun is right on the solar panel at midday. The specific calculation process is as follows:

1. Battery energy capacity calculation The battery voltage is 3.7v, the total energy is:

• 3000mAh × 3.7v = 11.1Wh

2. Effective charging power calculation The maximum power of the solar panel is 0.9W, the charging efficiency is 22%, the actual power input to the battery is:

• 0.9W × 22% = 0.198W

3. Charging time calculation Time T = total energy ÷ effective power = Total charging time

• 11.1Wh ÷ 0.198W ≈ 56.06 hours

6. FAQ

6.1 Why does the rain gauge have no data?

The WSC2-Compact-LS ships with the rain gauge set to counting mode by default (AT+COUNTMOD=1). In this mode, rainfall data is accumulated and reported in the uplink payload.

If you are not receiving rainfall data, it may be because the device has been accidentally switched to interrupt mode (AT+COUNTMOD=0). In interrupt mode, the device only sends an uplink trigger when rain is detected, without including rainfall count data.

Solution: Check the current rain gauge mode and reset it to counting mode if necessary.

• AT Command:

Command Example	Function	Response
AT+COUNTMOD=0	set to interrupt mode	OK
AT+COUNTMOD=1	set to counting mode	OK

• Downlink Command:

Format: Command Code (0x10) followed by 1 bytes time value.

• Example 1: Downlink Payload: 10 00 // Same as: AT+COUNTMOD=0 set to interrupt mode
• Example 2: Downlink Payload: 10 01 // Same as: AT+COUNTMOD=1 set to counting mode

6.2 Why is there no LED response when I press the button on the solar panel model?

If the LED does not light up when you press the button, it may be because the battery has entered protection mode.

Solution: To reactivate the battery, simply expose the solar panel to direct sunlight. For more details, please refer to: Battery Protection State (Apply to Solar Panel + Li-ion battery)
