# Uploading Calibration Files to Hovermap

This article explains how to upload color calibration files to Hovermap using a USB flash drive and the Hovermap Web UI.

> [!NOTE]
> Color calibration is performed by Emesent or an authorized partner. The calibration files used in this procedure are generated and provided by Emesent or an authorized partner. If a unit's color calibration appears incorrect, [contact a regional partner](https://www.emesent.com/resellers) or [Emesent Client Support](https://www.emesent.com/client-support/).

## What you will need

- A USB flash drive formatted in exFAT.
- The calibration files provided by Emesent for the specific Hovermap unit.
- Hovermap running Software version 3.x or later.
- Emesent Commander installed on a supported device.

## Procedure

### Step 1: Copy the calibration files

1. Create a new folder in the root directory of the USB flash drive used to upload the calibration files to Hovermap.
2. Name the folder in the following format: `<hardware_id>_calibration`

The `hardware_id` appears when the **Device** section is expanded in the Web UI to display the Hovermap's properties.

The numerical part of `hardware_id` matches the Hovermap unit serial number, which can also be read from the serial number sticker on the unit.

For example, folder names follow this pattern depending on Hovermap model:

| **Hovermap model** | **Folder name format** |
| --- | --- |
| Hovermap ST / ST-X | `st_xxxx_calibration` |

where `xxxx` is the numerical payload identifier (the unit serial number).

**Example:** for an ST-X with serial number 5150, the folder is named `ST_5150_calibration`.

1. Save the calibration files into the newly created folder.

### Step 2: Power on Hovermap

1. Connect a fully charged battery to Hovermap.
2. Power on Hovermap.
3. Wait for the startup sequence to complete. Proceed once the status LED displays slow pulsing Emesent blue.

### Step 3: Connect to the Hovermap network

1. On a supported tablet or Android phone, connect to the Hovermap Wi-Fi network:
  - **SSID:** `st_XXXX` (where `XXXX` is the unit serial number on the serial number sticker)
  - **Password:** `hovermap`

### Step 4: Open the Web UI

1. In **Commander**, select the (☰) icon in the top-left corner to open the **Options** menu.
2. Select **Web UI**. The Web UI opens.

#### Alternative: using a web browser

The **Web UI** is also accessible from any browser on a computer or mobile device, without Commander.

1. Open a web browser and navigate to **hover.map**.
2. Open **Device → Web UI**.

### Step 5: Insert the USB flash drive

1. Insert the prepared USB flash drive into Hovermap.

### Step 6: Upload calibration files

1. Ensure the USB flash drive is connected to Hovermap and the status LED displays slow pulsing Emesent blue.
2. In the Web UI, select **Yes** when prompted to apply the calibration file update.

1. The **Transfer Log** in the Web UI reports the outcome of the calibration file transfer. On a successful upload, the log confirms that the calibration files loaded successfully, then displays `Copying Complete - Remove USB`.

![Transfer Log reporting an aborted transfer because the payload calibration files are already up to date](https://cdn.document360.io/c908b593-57d7-4fc8-b409-592fc1051369/Images/Documentation/image(655).png)

> [!NOTE]
> In the example shown, the calibration file transfer is unsuccessful. The payload calibration files are already up to date, so Hovermap aborts the transfer without copying new files.

### Step 7: Restart Hovermap

1. Once the upload is complete, restart Hovermap.

## Outcome

The new calibration files are applied and used by Hovermap for colorization on future scans. For further support, contact [Emesent Client Support](https://www.emesent.com/client-support/).
