Milesight IoT gateway has built-in network server. When network server is enable, users can add LoRAWAN nodes/sensors to gateway and check the data directly. This article will guide you how to connect LoRaWAN nodes/sensors to Milesight Gateway.


  • Milesight LoRaWAN Gateway UG6x or UG8x.
  • LoRaWAN Node/Sensor (take Milesight EM300-TH as example).

Make sure sensor and gateway support the same LoRa frequency such as US915.


1. Before configuration,make sure the LoRaWAN node/sensor is not activated in other network servers. Take EM300-TH as example, run Milesight Toolbox App on smart phone via NFC or open Toolbox on PC via USB Type-C to makes sure Join Status of the sensor is De-Activate.

2. Go to Packet Forwarder -> Generalto enable localhost server.

Click Save & Apply.

3. Go to Network Server -> General to enable built-in Network Server.

Click Save & Apply.

4. Go to Network Server -> Applications to add application.

Name & Description: user-defined.

5. Go to Network Server -> Profiles to add a profile.

Name: user-defined.

Join Type & Class Type: same as the ones on the sensor.

6. Go to Network Server -> Deviceto add sensors.

Device Name & Description: user-defined.

Device EUI: the Device EUI of the sensor. For Milesight sensors, you can find it on the label or  ToolBox.

Device-Profile & Applications: the ones you added in the above steps.

Application Key (AppKey): the application key of the sensor. For Milesight sensors, it’s a general one (5572404c696e6b4c6f52613230313823). You can also find it on user guide.

If Join Type is ABP, please fill in  below parameters:

Device Address: the 5th to 12th digits of SN of sensor.

Network Session Key (NwkSKey)/Appcation Session Key (AppSKey): for Milesight sensors, it’s a general one (5572404C696E6B4C6F52613230313823). You can also find it on user guide.

Click Save & Apply.

7. After the sensor joins the gateway successfully, you can see it’s Activated.

Go to Network Server -> Packets of Milesight Gateway to check uplink data that sensor reports.

You can also see Join Status is Activate from corresponding software.
