Bluetooth Pairing in FeedComp
🗒️ NOTE: See Mobile Device Requirements for a list of recommended devices to use with FeedComp.
FeedComp uses Bluetooth to connect devices in two different ways, depending on the feature you're setting up. Understanding the difference helps you follow the correct setup steps and avoid connection issues.
| Loader View | Scale Connection |
|---|---|---|
What Pairs | A mobile device pairs to another mobile device | A scale pairs to a mobile device |
Why | So the loader operator can monitor and manage loading from a second phone or tablet | So the FeedComp app can receive live weight data from the scale |
Where you pair | In your device's Bluetooth settings (Android or iOS) | In your device's Bluetooth settings (Topcon Digi-Star) or directly through the scale app (Scale-Tec POINT) |
Where you connect in FeedComp | Feed > Loader View | Settings > Connect to Scale |
Pairing for Scale Connection (Scale to App)
Scale Connection pairs a physical scale to the FeedComp app on your mobile device via Bluetooth. This is how the app receives real-time weight data during feedings.
⚠️ IMPORTANT: Android Permission Setup
Android manages Bluetooth Low Energy (BLE) scanning under Location permissions. To ensure reliable discovery and automatic reconnection:
- Go to Android Settings > Apps > FeedComp > Permissions > Location.
- Set permission to Allow only while using the app (or Allow all the time). Do not select "Allow once" or "Ask every time."
- Toggle Use precise location to ON.
- Return to the FeedComp App Info screen and toggle Remove permissions if app is unused (or Pause app activity if unused) to OFF.
⚠️ IMPORTANT (Android Permission Setup): Android manages Bluetooth Low Energy (BLE) scanning under Location permissions. To ensure reliable discovery and automatic reconnection:
- Go to Android Settings > Apps > FeedComp > Permissions > Location.
- Set permission to Allow only while using the app (or Allow all the time). Do not select "Allow once" or "Ask every time."
- Toggle Use precise location to ON.
- Return to the FeedComp App Info screen and toggle Remove permissions if app is unused (or Pause app activity if unused) to OFF.
Scale Pairing Guidelines by Model
- Scale-Tec POINT:
- Configure the scale's display settings in the Scale-Tec POINT app, then connect to the scale in FeedComp under Settings > Connect to Scale.
- POINT scales support multiple active connections and continue advertising automatically.
- Topcon Digi-Star:
- Single Device Connection: Topcon scales only support one active Bluetooth connection at a time. Ensure no other nearby phone or tablet is currently connected to the scale before pairing.
- Proximity: Ensure your tablet is within 25 ft (8–9 m) of the scale indicator during pairing.
- Power-On Sequence: After turning the Topcon scale ON, wait 5 seconds before launching FeedComp. This gives the scale head unit time to initialize and begin broadcasting its Bluetooth advertisement signal.
- Enable Bluetooth on the scale indicator, pair the scale in your mobile device's Bluetooth settings, then connect in FeedComp under Settings > Connect to Scale.
For an overview of scale setup, including pre-installation checks, see Configure and Connect the Scale.
Pairing for Loader View (Device to Device)
Loader View requires two mobile devices — a mixer device and a loader device — paired to each other via Bluetooth.
- The mixer device is the primary phone or tablet mounted near the mixer, connected to the scale.
- The loader device is a second phone or tablet carried by the loader operator.
To use Loader View, first pair the two devices together in your device's Bluetooth settings, then connect them within FeedComp by going to Feed > Loader View.
💡TIP: If Loader View is not displaying as an option:
- On the device, go to User Profile
- Select Settings.
- Under Equipment, select the loader equipment.
- Save and exit.
