Description

Milesight gateway support BACnet/IP protocol. This article describes how to troubleshoot the problem of not getting the BACnet Object correctly in the gateway.

 

Requirement

  • Milesight Gateway : UG65/67 with firmware before 60.0.0.44 / UG56 with firmware before 56.0.0.5

(When the firmware version is later or equal to the above firmware version, kindly start checking from Tip2.)

 

 

Solution

Tip 1: 

Check if you select BACnet/IP protocol in gateway application settings:

 

 

Tip 2: 

Check if you select correct decoder for the sensor.

 

 

Tip 3: 

Check if the sensor is reporting uplink packets correctly and if the packets are being decoded correctly.

 

 

Tip 4: 

Check if the Object name and BACnet Object name settings in the packet information match.

Different JSON object types are named differently.

 

Plain Object:

BACnet Object Naming Rule of Plain Object is Device Name.Object Name

About Device Name, you can find it in Device list:

 

About Object Name, you can find it in packet info in Tip 3.

For example:  WS523-US915.voltage (After entering Device Name and LoRa Object, the Object Name is automatically generated.)

 


 

Nested JSON object:

BACnet Object Naming Rule of Nested Object is Device Name.Root Object.Object Name

Nested JSON Object Example:

{
  "data": {
    "battery": 86,
    "motor_position": 750,
    "motor_storke": 750,
    "temperature": 26.1,
    "temperature_target": 18
  }
}

About Device Name, you can find it in Device list:

 

 

About Root Object.Object Name, kindly check below to find the correct name.

 

For example:  WT101.data.battery (After entering Device Name and LoRa Object, the Object Name is automatically generated.)

 

 

Note:

If your sensor data packet's JSON type is nested JSON object type, please upgrade the firmware to the new version. UG6X: 60.0.0.44/UG56: 56.0.0.5

 

Tip 5:

If you still can not get the BACnet Object data correctly, please refer to How to Get Milesight Gateway Log Files to get the gateway log and share it with our support ([email protected]) for further checking.
