Velogic Studio connects directly to a gebioMized BLE saddle pressure mat over Bluetooth Low Energy, and streams its pressure data live into the fit. The mat is its own plugin, configured in the **GEBIOMIZED** panel. Heart rate, power and cadence sensors are handled by the separate Bluetooth plugin: see [Bluetooth Overview](/section-02-using-velogic-studio/bluetooth-overview.md). Both share your computer's one Bluetooth radio, so the hardware advice in [Bluetooth USB adapters: choosing and positioning](/section-02-using-velogic-studio/bluetooth-adapter.md) applies to either. ## Hardware Compatibility gebioMized has released several generations of transmitter hardware over the years. Only the latest BLE (Bluetooth Low Energy) transmitter is compatible with Velogic Studio. ### Transmitter Generations | Generation | Ports/Features | Velogic Compatible | Notes | | ----------------- | -------------------------- | :----------------: | --------------------------------------------------------------- | | BT-box (Ethernet) | Ethernet ports | ❌ | Superseded by WiFi in 2016 | | WiFi Transmitter | Jack plug beside mat port | ❌ | May have black or original housing. Superseded by BLE from 2023 | | BLE Transmitter | USB-C port beside mat port | ✅ | Current generation, required for Velogic integration | ![gebioMized transmitter generations - only the current BLE transmitter (right) is compatible](https://11145950-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FjxwtZYYk0lvusnMTywNR%2Fuploads%2Fgit-blob-72bd0ef269168965a40b82abb68b9a3b35764644%2Fgebiomized-transmitter-generations.png?alt=media) ### Identifying Your Transmitter To determine which transmitter you have, look at the ports on the device: * **USB-C port** next to the mat port → BLE Transmitter (compatible) * **Jack plug (3.5mm audio-style connector)** next to the mat port → WiFi Transmitter (not compatible) * **Ethernet ports** → BT-box (not compatible) If you have an older transmitter and wish to use the Velogic Studio integration, please contact gebioMized about upgrading to the BLE transmitter. ## LED Status Indicators ### Transmitter Status LED | Blink Sequence | Meaning | | --------------------------------- | ---------------------------------------------------------------------- | | Green (solid, during charging) | Charging in progress | | Green (flashing, during charging) | Battery fully charged - cable can be removed | | Red (solid or flashing) | **Error - remove charging cable immediately and contact manufacturer** | | Orange (flashing 1x every 10s) | Deep sleep mode | | Orange (flashing 1x every 3s) | Sleep mode | | Orange (flashing 2x) | Device is paired | | Orange (fast flashing) | Data transmission in progress | ### gebioMized USB dongle status LED This table describes the small USB dongle **supplied by gebioMized with the mat**. It is not your computer's own Bluetooth adapter - for that, see [Which Bluetooth adapter is Velogic Studio using?](#which-bluetooth-adapter-is-velogic-studio-using) below. | Blink Sequence | Meaning | | ------------------------- | -------------------------------------- | | Green (solid) | Device has power | | Blue (slow blinking) | Looking for connection | | Blue and green (blinking) | Found transmitter, connecting to it | | Blue (fast blinking) | Connection established, receiving data | ## Important Notes ### Battery Management * Battery life is typically several weeks/months thanks to Bluetooth low-energy technology * The device automatically switches to deep sleep mode when not in use to conserve power * It is not necessary to switch off the device - it has extremely low power consumption in sleep mode * **Do not switch off the device by removing the battery** * Optimal battery capacity is between 40-80% - constant charging to 100% is not necessary * This applies even if the device is not used for several weeks ### Battery Replacement * Only use rechargeable batteries of type **16340 RC123A** * Contact the manufacturer if you wish to replace the battery ## Configuration Everything to do with the pressure mat lives in the **GEBIOMIZED** panel on **Step 1: Configuration**. ![The GEBIOMIZED panel on Step 1: Configuration in Velogic Studio, below the webcam, Bluetooth and BikeFinder panels](https://11145950-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FjxwtZYYk0lvusnMTywNR%2Fuploads%2Fgit-blob-3cf9d1f76b4ed6f4bfe8772ef168db45ea0a0fa2%2Fgebiomized-step-1-configuration.png?alt=media) ### Adding a mat 1. Switch the mat's transmitter on and put it within range of the computer. 2. Open Velogic Studio and go to **Step 1: Configuration**. 3. Scroll down to the **GEBIOMIZED** panel. 4. Click **ADD PRESSURE MAT** and pick your mat from the list. ![The GEBIOMIZED panel showing one configured mat card, the ADD PRESSURE MAT button, and the status line reading "2 pressure mat(s) available to add."](https://11145950-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FjxwtZYYk0lvusnMTywNR%2Fuploads%2Fgit-blob-2168abddcc0ec09be1e3bd672660351feb61eab8%2Fgebiomized-add-pressure-mat.png?alt=media) **There is no "scan" button, and no scan to wait out.** The panel searches for mats continuously for as long as you are on Step 1, and the list updates itself as mats come and go. If a mat is awake and in range it will appear on its own; if it never appears, the problem is the mat or the radio rather than a scan that has finished. The status line under the panel tells you what it can currently see: | The panel says | What it means | | ------------------------------------------- | -------------------------------------------- | | No pressure mats detected; scanning. | Nothing found yet, and nothing configured | | No other pressure mats detected; scanning. | Everything it can see is already added | | *N* pressure mat(s) available to add. | *N* mats found that you have not added yet | | Bluetooth is not available on this machine. | Velogic Studio has no usable Bluetooth radio | **ADD PRESSURE MAT** only appears when there is something to add. Each entry in its list is the transmitter's serial number followed by its current signal strength, for example `FC4BD743FCDB (-72 dBm)`. A mat you have already added is never offered again, so you cannot add the same mat twice. ### The mat card Every mat you add gets its own card in the panel. ![Two gebioMized mat cards: a deactivated card offering RENAME, ACTIVATE and REMOVE, and a connected card streaming a live saddle pressure map with its licence expiry underneath](https://11145950-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FjxwtZYYk0lvusnMTywNR%2Fuploads%2Fgit-blob-75ef2cb7e2c3a78b990da07a3eea17ff02dadd2d%2Fgebiomized-mat-cards-connected.png?alt=media) The card header shows the mat's name - its serial number until you change it - and, when the card is collapsed, its connection state on the right. | Control | What it does | | -------------- | ---------------------------------------------------------------------------------------------------------------------- | | **RENAME** | Give the mat a friendlier name. Names must be unique, so two mats cannot share one. | | **DEACTIVATE** | Keep the mat configured but stop using it. The card collapses and the mat is no longer offered to the rest of the fit. | | **ACTIVATE** | Shown in place of DEACTIVATE on a deactivated card. Brings it back into use. | | **REMOVE** | Delete the card. Velogic Studio asks *"Are you sure you want to remove this sensor?"* first. | Removing a mat deletes its settings only - **your gebioMized licence is kept**. If you add the same mat again later it picks the existing licence straight back up, with no need to go back to gebioMized for a new one. An expanded, active card also shows: * **The connection state**, one of *Disconnected*, *Connecting*, *Checking license...*, *Downloading calibration...*, *Waiting to retry* or *Connected*. While it is checking the licence or downloading calibration a **Cancel** link appears beside it. * **The licence line**, normally *License expires: (date)*. If Velogic Studio cannot reach gebioMized it says so instead - *Could not reach gebioMized — using your saved license*, *Cannot verify license — check internet connection*, *License invalid — contact *, or *Can't verify saddle pressure mat license while offline — please sign in*. * **Battery**, as a percentage, when the mat reports one. * **Signal**, as *Excellent*, *Good*, *Fair* or *Poor*. Hover over it for the raw value in dBm. The row is hidden entirely when there is no current reading, so it never shows you a stale figure as though it were live. * **Bluetooth adapter**, naming the radio your computer is using - see [the next section](#which-bluetooth-adapter-is-velogic-studio-using). ### A connected mat Once the card reaches **Connected** it shows the mat's live pressure map, updating in real time. That is the confirmation that the mat is streaming: a saddle outline with the current pressure distribution painted onto it, as in the right-hand card above. If the signal is poor or the map stalls, the fix is almost always where the computer's Bluetooth radio is, rather than anything in the software - see [Bluetooth USB adapters: choosing and positioning](/section-02-using-velogic-studio/bluetooth-adapter.md). ## Which Bluetooth adapter is Velogic Studio using? > **This section is about your computer's own Bluetooth adapter** - the radio built into your PC or Mac, or a USB Bluetooth adapter plugged into it. It is **not** about the [gebioMized USB dongle](#gebiomized-usb-dongle-status-led) supplied with the mat, which is a different device entirely. **Velogic Studio cannot choose which Bluetooth adapter it uses. The operating system chooses, and Velogic Studio reports the choice.** Neither Windows nor macOS gives an application a way to pick its Bluetooth radio. The **Bluetooth adapter** row on the mat card is therefore a mirror, not a setting: it tells you which radio the operating system has settled on. ### On Windows Windows uses one Bluetooth radio at a time, and will usually select a plug-in USB adapter automatically. The **Bluetooth adapter** row on the mat card names the radio in use, so you can confirm which one it settled on. If you need to force the choice - for example onto a USB adapter on an extension cable positioned close to the mat - disable the one you do not want: 1. Open **Device Manager**. 2. Expand **Bluetooth**. 3. Right-click the adapter you do **not** want and choose **Disable device**. 4. **Check the Bluetooth adapter row on the mat card** to confirm which radio is now in use. Which adapter to buy, where to mount it, and what to run it on are all covered on [Bluetooth USB adapters: choosing and positioning](/section-02-using-velogic-studio/bluetooth-adapter.md). #### What the Bluetooth adapter row can say | The row says | What it means | | ----------------------------------------- | ------------------------------------------------------------------ | | *(adapter name)* (built in) | Windows is using the radio built into the computer | | *(adapter name)* (plug-in USB adapter) | Windows is using a plug-in USB adapter | | Built-in adapter / Plug-in USB adapter | As above, but the operating system gave no name for it | | No Bluetooth adapter found | The operating system reports no Bluetooth radio at all | | Bluetooth adapter could not be identified | The query failed. This is deliberately different from "no adapter" | ### On macOS **macOS always uses the Bluetooth controller built into the Mac, and plug-in USB Bluetooth adapters are not supported.** Neither Velogic Studio nor macOS can change that, so there is nothing to switch. The row reads *macOS does not report which adapter it uses* rather than naming a controller. To improve the signal on a Mac, move the Mac closer to the mat or clear what is between them. The placement advice in [Where to put the adapter](/section-02-using-velogic-studio/bluetooth-adapter.md#where-to-put-the-adapter) applies to a Mac's built-in radio just as much as it does to a USB adapter.
