Weighbridge Dongle: Setup Guide and Troubleshooting

Introduction
The AgriChain Weighbridge Dongle integrates with your existing weighbridge to seamlessly capture weight data and sync it with the AgriChain Mobile App. This helps streamline operations and improve the accuracy of data capture and record-keeping.

AgriChain will send you a package with all the required hardware to set up the weighbridge integration. The package includes:

• 1x AgriChain Dongle

• 1x USB Power Cord

Weighbridge Configuration Requirements:

Before connecting the dongle, your weighbridge indicator must be configured to one of the following supported modes:

• Mettler Legacy String

  • Settings: 8N1, 9600 baud rate, continuous output

• Rinstrum - Ranger A (Recommended)

  • Settings: 8N1, 9600 baud rate, continuous output

The cable coming from your weighbridge should be an RS232 data cord. Please coordinate with your weighbridge technician to ensure proper calibration and setup. Important: Please ensure that the DB9 cable does not supply power on Pin 9, and that on the dongle's end, only Pin 3 is wired and Pin 2 on the weighbridge's end if the weighbridge uses a DB9 cable. 

Steps to Configure and Connect

1. Configure the Weighbridge Software
   Set the indicator to either Mettler or Rinstrum configuration. 

2. Notify AgriChain Support
   Once configured, reach out to AgriChain Support via the 'question mark' Help Widget located at the top right corner of the screen so that we can assist you in turning ON the integration. To submit a ticket, locate the 'question mark' Help Widget and click on 'Contact Us', followed by the details below:

   • The configuration used (Mettler or Rinstrum)

   • Site location(s) where the weighbridge is installed

3. Prepare Your Mobile Device

   • Delete and reinstall the AgriChain mobile app.

   • Ensure the mobile device is running iOS 16 / iPadOS 16 or later.

   • Recommended device: iPad or iPhone with a 12MP rear-facing camera.

4. Connect the Dongle to AgriChain

   • Launch the AgriChain Mobile App.

   • Tap the 'Mamburger' menu icon (top left) and select Settings.

   • Go to Weighbridge Status

   • This will bring up the Device Management Screen. Please look for the dongle to connect. The dongle should be named either BlueSnap or SerialO. 

   • Follow the on-screen prompts to connect the dongle via Bluetooth.

   • Once connected, the device will move to the 'Connected Devices' row.

   • When powered on, the dongle will show a green light; it will turn solid blue once connected.

Troubleshooting Issues

If the dongle is flashing orange and not connecting to the weighbridge, try the following steps:

Basic Troubleshooting

• Turn off Bluetooth and back on. 
  

• Restart your iPad and reconnect.

Use yACK FAST for Diagnostics

• Install the yACK FAST app from:

  • Apple App Store

  • Google Play Store

• This app reads serial data output from the dongle to confirm whether data is being sent correctly.

• If no data appears, the weighbridge configuration may need to be reviewed by your technician.

Bluetooth is unauthorised for application:

You will need to allow Bluetooth Access for the AgriChain App. To resolve this, please follow the steps below:

1. Navigate to your device's Settings page
2. Tap into 'Apps' or search for AgriChain.
3. Once you are in AgriChain, please turn on 'Bluetooth'

Advanced Troubleshooting (If Issue Persists)

We also recommend trying the following:

1. Ensure Everything is Up to Date
