This little dongle worked on the first try!

This little dongle worked on the first try! ### ⭐⭐⭐⭐ Works like a charm (once you update the driver) *by J***P on July 2, 2018* Had to update the driver on device manager once that happened worked like a charm with my cycleops on zwift and rouvy ### ⭐⭐⭐⭐⭐ A BT dongle for programmers... *by M***N on July 29, 2014* If you're not a programmer, then this isn't the Bluetooth dongle you are looking for - however, if you are, and you do anything indepth with Bluetooth 4.0 LE, then this is the best money you'll ever spend. Unlike normal BT dongles, when this is installed in your computer, it shows up using the SPP (serial port) driver, and is accessible only via that - you're not going to be using your mouse with it. The first thing you'll want to do is download the SDK from their site (which you need to create an account for, which is lame, and only because this product is so awesome do I not ding them a star for this). Once it's installed, the real treat is their GUI tool - with this you can connect to bluetooth devices, view their GATT, read and write to specific UUID's - basically anything you'd want to do as a host. You can also configure it to act as a device, but I haven't needed to do that, so I can't speak to how it works, but based on the host side, it's probably great. For my purposes, I'm using it to access HRM devices on Windows 7 (thanks MS for not including all the BT profiles, talk about lame) - and for that I use their native C API. It's VERY different than any other API's I've used before (and I've used alot), and a bit clunky to work with - but it's really geared more towards embedded devices I suspect. Either way, you can quickly get something working in a few hours, and from there the sky's the limit. A very unique device, and an exceptional value. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/7050816-bluetooth-802-15-1-modules-ble-usb-dongle-4-0](https://www.desertcart.co.uk/products/7050816-bluetooth-802-15-1-modules-ble-usb-dongle-4-0) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
