Configuring the Wi-Fi

Wi-Fi for the IoTReady data logger devices can be configured using QR codes generated in a specific format that has been detailed in this document.

To create these QR codes, any QR code generator software application can be used.
For this guide, we will use the-qrcode-generator.com.

When using this website, make sure you are using the "FREE TEXT" tab as seen below in the images.

  • QR code for SSID: conf:ssid:wifi_name
    Where wifi_name is the SSID of the Wi-Fi network.

  • QR code for Password: conf:password:pwd
    Where pwd is the password of the Wi-Fi network.

IoTReady WiFi Configuration App

  1. Scan the QR codes (first the SSID, then the password) generated using the barcode scanner attached to the data logger.
  2. You should see the wifi_name and pwd on the LCD display.
  3. Restart the device.
  4. The device will now try to connect to the Wi-Fi credentials provided using the QR codes.

Usage

  1. The user places a package with a Unique ID in the Data Logger.
  2. The data logger scans the ID.
  3. The ID will appear on the Data Logger's screen.
    For some use cases, additional details like hub and trip information will also be displayed.
  4. Once the ID appears, place the package on the weighing scale.
  5. When the weight stabilizes, a yellow indication will appear, meaning the data logger is sending data to the server.

  • A green light means the audit is successful.
  • A red light means the audit has failed.
  • A blue light indicates an API error.

OTA Flow: Updating the Software

Before You Start:

  • The laptop you're using must be connected to the same Wi-Fi as the device.

To Initiate the Update:

  1. Enter the device's IP Address in the address bar, followed by /OTA.
  2. Click "Browse" to select the update file from your computer/laptop.
  3. Press "Update" after selecting the file; your device will start updating.
  4. You can track the progress on your computer/laptop screen.
  5. Once the update is successful, restart the device.
  6. After restarting, the device screen will display the updated version name.

Troubleshooting

  1. If the data logger does not show a yellow indication:

    • Check that the weight has stabilized:
      • Ensure the surface is even.
      • Ensure the table or location of the weighing scale is stable.
      • Ensure there are no external disturbances affecting the scale.
  2. If there is a server failure (indicated by a Blue Light):

    • Contact your IT team for assistance.
