The information on this page applies to pre-release versions of Velogic Studio and may not yet be available in the shipping version. Features and functionality may change before the final release. If your PC has no Bluetooth, has unreliable Bluetooth, or lives in a cabinet away from the fit bike, a USB Bluetooth adapter will fix it, provided you put it in the right place. This applies to everything Velogic Studio connects to over Bluetooth: heart rate, power and cadence sensors via the [Bluetooth plugin](/section-02-using-velogic-studio/bluetooth-overview.md), and the [gebioMized saddle pressure mat](/section-02-using-velogic-studio/gebiomized-integration.md). They share one radio, so one well-placed adapter serves them all. ## Which adapter to buy [**TP-Link UB500**](https://www.amazon.com/TP-Link-Bluetooth-Receiver-Controller-UB500/dp/B09DMP6T22)**.** Around US$15, sold everywhere, and Windows installs the driver for it automatically. Handles up to 7 sensors at once. ### If your PC only has USB-C ports Use a small USB-C to USB-A adapter, then an extension cable. Avoid running the Bluetooth adapter off a USB hub: hubs, particularly USB 3 ones, are a source of 2.4 GHz noise, and you would be parking the radio right next to it. ## Where to put the adapter **Mount the adapter about 1 m above the floor, in line of sight of your sensors, and away from the PC.** * **About 1 m above the floor.** * **Line of sight to the bike.** Keep cabinet doors, metal shelving and monitors out of the path. * **Away from the PC.** The computer, its power supply, monitors, Wi-Fi access points and USB 3 devices are all sources of 2.4 GHz interference. Two metres of extension cable gets the adapter clear of them, and does more good than any upgrade you can buy. * **Fix it in place** with tape, a cable clip or a strip of velcro. If your PC is in a cupboard or cabinet, an extension cable is not optional. ### USB extension cables Any USB 2.0 A-male to A-female extension works. | Length | Cable | | ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | 1 m / 3.3 ft | [Amazon Basics](https://www.amazon.com/AmazonBasics-Male-Female-Extension-Cable/dp/B001TH7GV4) | | 2 m / 6.5 ft | [Amazon Basics](https://www.amazon.com/AmazonBasics-Extension-Cable-Male-Female/dp/B00NH136GE) | | 3 m / 9.8 ft | [Amazon Basics](https://www.amazon.com/AmazonBasics-Extension-Cable-Male-Female/dp/B00NH11PEY) | | 10 m / 32 ft | [Amazon Basics active](https://www.amazon.com/Amazon-Basics-Extension-Repeater-High-Speed/dp/B01L81WQ2O) or [Plugable active](https://www.amazon.com/Plugable-Meter-Active-Extension-Female/dp/B004AGX4YO) | 2 m suits most rooms. Past 5 m you need an active (powered) cable; do not chain two passive ones together. Any equivalent will do if these are unavailable: [browse USB 2.0 extension cables](https://www.amazon.com/s?k=USB+2.0+extension+cable+A+male+to+A+female). ## Setting it up 1. **Plug the adapter in with the PC connected to the internet.** Windows downloads the driver automatically. If the PC is offline the first time, the adapter shows up as an unrecognised device. This is the most common reason for "the adapter did not work". 2. **Mount the adapter** as described in [Where to put the adapter](#where-to-put-the-adapter). 3. **Switch your sensors on.** Velogic Studio scans for them automatically. See [Bluetooth Overview](/section-02-using-velogic-studio/bluetooth-overview.md), or [gebioMized saddle pressure mat integration](/section-02-using-velogic-studio/gebiomized-integration.md) for the mat. Any spare USB port will do. If you have a USB 2.0 port (usually black rather than blue), use it, but getting the adapter away from the computer matters far more than which port you pick. Windows uses one Bluetooth radio at a time, and will usually select a plug-in USB adapter automatically. If you need to force it, disable the built-in adapter in Device Manager: expand **Bluetooth**, right-click the built-in adapter, choose **Disable device**. ## Getting help If sensors still will not connect, contact us at with the make and model of your adapter, where you have mounted it, and a description of the problem. For sensor-specific troubleshooting, see [Bluetooth Overview](/section-02-using-velogic-studio/bluetooth-overview.md) for heart rate, power and cadence, or [gebioMized saddle pressure mat integration](/section-02-using-velogic-studio/gebiomized-integration.md) for the mat. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.velogicfit.com/section-02-using-velogic-studio/bluetooth-adapter.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
