Whether you’re deploying smart building solutions, industrial monitoring systems, or city-wide IoT networks, this integration ensures secure, scalable, and vendor-neutral LoRaWAN connectivity.

Let’s walk through the full process.

✅ Prerequisites
Before starting, ensure:

✅ 1× Milesight UG56 LoRaWAN Gateway
✅ 1× Milesight WS101 LoRaWAN Temperature & Humidity Sensor
✅ Running instance of ThinkLink Edge TKE132 LoRaWAN Server
✅ Computer with access to the TKE132 web interface
✅ NFC handheld tool or NFC-enabled device to configure WS101
⚙️ This guide uses AS923 frequency band as an example but can be adapted for EU868, US915, etc.

🖥️ Step 1: Login to TKE132 and Obtain IP Address
ThinkLink Edge runs locally on-premise. To begin, retrieve its IP address via the configuration portal:

🌐 Enter in browser:
http://www.thinklink-edge:19091

📌 Log in to tke-conf and record the actual IP address assigned to TKE132 (e.g., 192.168.1.100).

🔁 Note: This step is typically needed only during initial setup or after network changes. Save this IP — it will be used in the UG56 configuration.

📎 Reference:[EN] TKE13 ThinkLink-Edge Specification

🌐 Step 2: Configure Milesight UG56 Gateway
Now configure the UG56 to forward packets to TKE132 via GWMP protocol (port 1770).

2.1 Access UG56 Web GUI
Open browser and go to default IP:
👉 http://192.168.1.1

2.2 Navigate to Packet Forwarder Settings
Go to:
🔧 LoRaWAN > Packet Forwarder > General

Click “+” to add a new Network Server destination.

2.3 Set GWMP Connection Parameters
Fill in:

Enable: ✅ Checked
Type: Semtech (standard GWMP mode)
Server Address: TKE132_IP_ADDRESS
Port Up: 1770
Port Down: 1770
✅ Click “Save & Apply”

➡️ The UG56 will now forward all received LoRaWAN uplinks to TKE132.

🔐 Step 3: Add UG56 Gateway to ThinkLink Whitelist
Next, authorize the gateway in ThinkLink.

In ThinkLink Web UI:
📍 Go to:
Gateways > Add Gateway

Fill in:

EUI: Copy from UG56’s label or status page
Type: Select GWMP
PIN Code: User-defined (optional management field)
✅ Submit

Your gateway is now authenticated and ready to relay data.

📡 Step 4: Register WS101 Device in TKE132 (OTAA Mode)
To allow the sensor to join, pre-register its credentials in OTAA mode.

In TKE132:
📍 Operations > Device Management > LoRaWAN Profiles > New

devEuiFrom WS101 physical label or NFC read

standard AS923

app_keye.g., 88888888888888888888888888888888

💡 Other fields (lw_ver, class_mode) are auto-filled based on selected standard.

✅ Save profile

Now TKE132 expects this device to connect via OTAA.

🛠️ Step 5: Configure WS101 Sensor for Re-Joining
Use the handheld configurator or NFC app to update the WS101 settings so it can join the new network.

In Configuration Tool:

📍 Find LoRaWAN settings screen

Setting

Value App Key

Same as above app_key

Device EUI Verify matches devEui

App EUI Auto-read; verify match

Region AS923

Join Mode OTAA

✅ Click Write / Save to push config to sensor

🔁 After write completes, WS101 restarts and attempts OTAA join.

🟢 Success indication: LED behavior per user manual (e.g., solid light = joined)

🧩 Step 6: Add Payload Decoder (Thing Model)
Raw hex payloads need decoding. We’ll import Milesight’s official decoder.

6.1 Get Decoder Script
Find the Payload Decoder JavaScript function in:
📄 ws101-user-guide-en.pdf — Page 13 Or GitHub repo: @milesight-iot

Example snippet:

function Decoder(bytes, port) {
var decoded = {};
// temperature, humidity parsing logic...
return decoded;
}
6.2 Create Thing Model in ThinkLink
📍 Go to:
Model Management > Thing Model > New

Type: ChirpStack (since TKE132 uses ChirpStack core)
Name: WS101_AS923_Decoder
Decoder Code: Paste full script into editor
✅ Save model

This allows TKE132 to interpret raw binary data from WS101.

💾 Step 7: Create Operational Device & Mount Model
Final step: Register operational device and bind payload model.

📍 Operations > Device Management > Devices > Add

EUI Must match registered devEui

Name e.g., WS101_Lab_Sensor

Type LoRaWAN

✅ Save device

Then go to:
📎 Device Details > Thing Model Section > Add

Select previously created model: WS101_AS923_Decoder

✅ Confirm binding

✅ DONE!

You should now see real-time temperature and humidity updates under:
📍 Real-time Data or History Data dashboards in ThinkLink.

🔍 Common Issues & Troubleshooting
Problem Solution

❌ UG56 cannot reach TKE132

➜ Verify IP and ping test; check firewall allows UDP port 1770

❌ Gateway not appearing online

➜ Confirm correct EUI and type=GWMP in whitelist

❌ WS101 fails to join

➜ Double-check app_key, devEUI, region, and join mode

Introduction of LoRaWAN Gateway with Integrated NS

zhao mingfei — Wed, 22 Oct 2025 12:34:25 +0000

In the early days of LoRaWAN, integrating a Network Server (NS) directly into the gateway seemed like a smart shortcut — reducing complexity and cost for small-scale deployments. After all, the NS is the brain of any LoRaWAN network, responsible for device management, data routing, security, and resource allocation.

✅ Where Gateway-Integrated NS Still Makes Sense

There are scenarios where embedding NS into the gateway works:

Rapid prototyping: For initial testing or proof-of-concept projects, an integrated NS eliminates the need to set up cloud infrastructure.
Offline or remote areas: In locations with poor internet connectivity, local NS operation ensures network functionality without cloud dependency.
Local data processing needs: Some applications require low-latency edge responses or avoid sending sensitive data to the cloud.
The Limitations of Built-in NS
As IoT scales, so do its challenges. Here’s why gateway-integrated NS is falling behind:

No Multi-Gateway Roaming
Each gateway operates in isolation. Devices can’t roam seamlessly between gateways — critical for reliable coverage in industrial or city-wide deployments.
Limited Capacity
Most embedded NS solutions support only 20–100 devices. Hardly enough for real-world deployments beyond lab experiments.
Feature Gaps
Missing essential capabilities: advanced security (end-to-end encryption), dynamic frequency planning, OTA updates, rule engines, and integration with BACnet, Home Assistant, etc.
Poor Scalability & Maintenance
Adding more gateways means fragmented networks. No centralized view = harder troubleshooting, upgrades, and analytics.
Data Silos
With each gateway storing data separately, aggregating insights across sites becomes nearly impossible — a major roadblock for enterprise adoption.
💡 The Better Alternative: Edge-Based NS Like ThinkLink Edge
Enter ThinkLink Edge by Manthink, a game-changer for cost-effective yet powerful LoRaWAN deployment.

ThinkLink Edge runs on dedicated edge hardware (8-core CPU, 8GB RAM) with:

Full support for global LoRaWAN standards
Support for up to 1,000 devices per instance
Pre-installed open-source platforms: Home Assistant, ThingsBoard CE
Native integration with BACnet, MQTT, HTTP APIs
Powerful rule engine and centralized dashboard
And the best part? You get enterprise-grade NS features at just ~$290 in hardware — far cheaper and more capable than stacking multiple NS-enabled gateways.

Now you gain:
✅ Seamless multi-gateway coordination
✅ Centralized device & data management
✅ True scalability without vendor lock-in
✅ Local processing + optional cloud sync
