## Device does not connect to scale

- Confirm Bluetooth is enabled on both the device and the scale head unit. The scale should show as "connected" in the Bluetooth settings:
  - ****<font color="#0C121D">**Android or iOS\:** </font>Go to :inlineImage[]{src="https://api.archbee.com/api/optimize/3h8pSJcGUXEi4HGCCYPTA/IeET2v6nc5ilaqgmxjMxI_gear-green.png" alt caption width="25" height="25"} **Settings**, select **Bluetooth**, and toggle on.&#x20;
  - **Topcon Digi-Star Scale:&#x20;**<font color="#0C121D">S</font>ee [Topcon Digi-Star Scale](docId:1mG2kfqVWauAQVNlFozKV) for help.&#x20;
  - <font color="#0C121D">**Scale-Tec POINT Scale\:** S</font>ee [Scale-Tec POINT Scale](docId\:bVHgbQ02wUZgM-1KzfHHu) for help.&#x20;
- Turn the scale off and back on, then reconnect the scale from FeedComp.
- Close FeedComp on the device, reopen it, and retry pairing:
  - **Android**: Tap on the 3 vertical lines in the bottom left corner, then swipe up on the FeedComp app to close the app.
  - **iOS**: Swipe up from the bottom of the screen and pause in the middle to open the App Switcher, then swipe up on the FeedComp app to close the app.
- Restart both the device and the scale.
- Check that no other device is currently paired to the scale as the scale can only connect to one device at a time.

:::hint{type="info" indent="1"}
**NOTE:** If the FeedComp app closed the last time it was connected to the scale, the Bluetooth connection may still be active. The app only allows one connection at a time and may think that you're trying to connect a second device if this happens.&#x20;
:::

- Make sure the app language is set to English (some scales fail to pair when the app is set to another language).
  - Tap on the :inlineImage[]{src="https://api.archbee.com/api/optimize/3h8pSJcGUXEi4HGCCYPTA/qxc2Z9A49LdR2kLA5_HBT_language.png" alt caption width="22" height="20"} icon in the top right corner to select English.
- If using Loader View, confirm each device has been assigned a distinct role (Mixer vs. Loader) and named properly — **roles cannot be swapped without reinstalling the app.**
- Verify the scale head firmware is up to date using the scale manufacturer's native app (Scale-Tec or Digi-Star) **before** launching FeedComp.
  - ****<font color="#0C121D">**Topcon Digi-Star Scale\:** </font>Contact [VAS Support](https://vas.com/contact-support/).
  - ****<font color="#0C121D">**Scale-Tec POINT Scale\:** </font>Connect the device to the internet. After opening the POINT app, it will automatically notify you if a firmware update is available. Follow the on-screen prompts to install the update if one is available.

## Scale connection drops if tablet auto-connects to WiFi

If the feed tractor passes near a WiFi location, the tablet can auto-connect to that WiFi, triggering a data refresh, and the app may freeze mid-feeding.

- Use FeedComp i&#x6E;**&#x20;Offline Mode** by turning off WiFi on the device before starting any feedin&#x67;**.** This is the primary workaround.
  - ****<font color="#0C121D">**Android\:** </font>Swipe down and toggle off WiFi or go to :inlineImage[]{src="https://api.archbee.com/api/optimize/3h8pSJcGUXEi4HGCCYPTA/IeET2v6nc5ilaqgmxjMxI_gear-green.png" alt caption width="25" height="25"} **Settings**, then select **Connections&#x20;**&#x61;nd toggle off WiFi.
  - ****<font color="#0C121D">**iOS\:** </font>Go to :inlineImage[]{src="https://api.archbee.com/api/optimize/3h8pSJcGUXEi4HGCCYPTA/IeET2v6nc5ilaqgmxjMxI_gear-green.png" alt caption width="25" height="25"} **Settings**, then select **WiFi&#x20;**&#x61;nd toggle it off.

:::hint{type="info"}
&#x20;**NOTE:** For the best experience, we recommend maintaining a data connection during feeding. If your feed bunk or mixing area lacks coverage, a cellular tablet or WiFi range extender can help. See the [Pre-Installation Checklist](docId:10mZSqo9Ndlv_hHGJKc-X) for details.
:::

- If WiFi can't be disabled, avoid feeding routes that go through areas with WiFi coverage.
- Check that no device restrictions (battery saver, low power mode) are active — these can reduce Bluetooth range and reliability.
  - ****<font color="#0C121D">**Android\:** </font>Go to :inlineImage[]{src="https://api.archbee.com/api/optimize/3h8pSJcGUXEi4HGCCYPTA/IeET2v6nc5ilaqgmxjMxI_gear-green.png" alt caption width="25" height="25"} **Settings**, then select **Battery** and toggle off **Power Saving**.
  - ****<font color="#0C121D">**iOS\:** </font>Go to :inlineImage[]{src="https://api.archbee.com/api/optimize/3h8pSJcGUXEi4HGCCYPTA/IeET2v6nc5ilaqgmxjMxI_gear-green.png" alt caption width="25" height="25"} **Settings**, then select **Battery** and toggle off **Low Power Mode**.

## Need to re-enter mixer/scale settings in app before feeding

After pairing successfully, the Bluetooth connection doesn't persist between each feeding session, and you need to re-pair the device before feeding can begin:

1. Close the app and reopen, then attempt to pair again.
2. If the issue persists, uninstall and reinstall the FeedComp app. See<font color="#22C55E"> </font>[Install the FeedComp App](docId\:yBQPHGMUvW7Ocs3vTMBDm) to learn more.

:::hint{type="warning"}
⚠&#xFE0F;**&#x20; IMPORTANT:&#x20;**&#x52;einstalling the app resets the settings in the FeedComp app.&#x20;

## Scale weight is reading zero and Bluetooth is connected

This is almost always a physical hardware issue, not an app issue.

- Check the physical load cell cable connections at the mixer and junction box — loose or corroded wiring is the most common cause.
- Inspect the mixer for rusted wires at the junction box; if corroded, a farm mechanic should replace them (risk of breakage).
- Verify the scale head's **Display Count** setting is set to **C1** (not C0) to prevent invalid values from syncing ([Scale-Tec POINT Scale](docId\:bVHgbQ02wUZgM-1KzfHHu) only).
- Confirm the scale is not stuck in **Gross/Net lock** mode — toggle back to Gross if needed.
  - ****<font color="#0C121D">**Topcon Digi-Star Scale\:** </font>The **T/R button** toggles between Net and Gross each time you press it. On the scale, check the flashing arrow on the side of the display points to **GROSS**, which allows the display to show the total weight.
  - ****<font color="#0C121D">**Scale-Tec POINT scale\:** </font>Press the square stop button (■) on the POINT scale to place it back into **Gross Mode**.
- Check that the scale isn't in **Hold** mode. To resolve this, see Scale is stuck in "Hold" mode below.&#x20;

## Scale is stuck in "On Hold" mode

Scales can enter a hardware-level **Hold** that conflicts with the FeedComp pause function.

- In the FeedComp app, verify the **Pause icon&#x20;**("On Hold" button) is no longer active. It should only display during the loading and dropping phases. When tapped, the connected scale enters "On Hold" mode.

::Image[]{src="https://api.archbee.com/api/optimize/3h8pSJcGUXEi4HGCCYPTA/4UtddvRT5coBXZhaGF4m6_pause-indicator.png" size="28" width="364" height="267" darkWidth="364" darkHeight="267" position="flex-start" showCaption="false" indent="1"}

- Check the Hold settings on the scale:
  - **Topcon Digi-star Scale**: For help, view [Configure Scale Settings for Topcon Digi-Star Scales](docId:1mG2kfqVWauAQVNlFozKV).
  - **Scale-Tec POINT Scale**: Press the square stop butto&#x6E;**&#x20;(■)** on the scale head. The scale should return to **Gross Mode** and the weight will begin updating live again.
- If the scale won't leave "On Hold" mode, turn the scale off and back on, then reconnect via Bluetooth.

## "Bouncing" weights and premature auto-advance

If you continue to experience bouncing weights, delayed stabilization, or premature auto-advances with your Topcon Digi-Star scale, [Contact Us](docId:4ghs_95g97Ps-fCkKm8sU) to adjust your scale settings remotely. VAS can adjust motion filter settings per scale from our side, and no changes to the scale head or on-site equipment are needed.&#x20;

## How to download a log file

1. Open **FeedComp** on your device and tap the **profile icon** in the top-right corner.
2. Scroll to the bottom of the profile page to the **App Version** section, located just above the **Sign Out&#x20;**&#x62;utton.
3. Tap the **version number**. A message confirms the logs were saved to the device.
4. Open the device **Files** app.

:::hint{type="info" indent="1"}
**TIP:** Use the search feature in the app list to fine "files" if the icon is not on the home screen.
:::

5. Navigate to the **Downloads** folder, typically found under **Internal Storage**.
6. Locate the **log file**. The filename uses this format: FC\_\[IntegrationID]\_Device\_logs\_\[Date]T\[Time].txt
7. Coordinate sharing the log file with Support or email it to: **fwsupport\@vas**.

:::hint{type="warning" indent="1"}
**NOTE:** Log files are only stored on the device for approximately **48 hours.** Share them with VAS Support as soon as possible after encountering an issue.
