- Bluetooth Connection Tips

Bluetooth Requirements

Before you start the setup, make sure the following is ready:

• Your iPhone
• The turfRad mobile app installed
• The sensor powered on and nearby

Bluetooth is only used during the initial configuration process to connect your phone to the sensor or if you want to monitor your file uploads on the App. 

iPhone Settings Checklist

To ensure a smooth connection, please check the following settings on your iPhone:

Bluetooth

• Bluetooth must be enabled
• Go to: Settings → Bluetooth → Turn ON

Location Services

• Location access is required for the app to detect nearby devices
• Go to:
  Settings → Privacy & Security → Location Services → ON

• Ensure the turfRad app has permission set to:
  • Always
  • Precise Location (toggled on)

App Permissions

• When opening the app for the first time, allow:
  • Bluetooth access
  • Location access

How Bluetooth Connection Works

The turfRad app automatically handles the Bluetooth connection process.

• The app searches for nearby sensors via Bluetooth
• You select your sensor and tap “Connect”
• The app then pairs and connects to the sensor directly

Important:

•  

  Do not try to connect to the sensor manually in your iPhone Bluetooth settings. The connection must be done inside the turfRad app.

• Do not try to connect multiple phones at the same time to the sensors.

Best Practices for a Stable Connection

Follow these tips to avoid connection issues:

• Keep your phone close to the sensor (within a few meters)
• Ensure the sensor is powered on
• Avoid interference from:
  • Other Bluetooth devices
  • Strong WiFi routers directly next to the sensor
• Stay on the setup screen in the app during connection

Common Issues & Fixes

• Make sure Bluetooth is turned ON
• Restart Bluetooth (toggle OFF → ON)

Good to Know

• Bluetooth is only used during initial setup
