KinivoUSB Bluetooth Adapter for PC BTD400 (Bluetooth 4.0 Dongle Receiver, Low Energy) - Compatible with Windows 11/10/8.1/8, Raspberry Pi, Linux, Laptop & Headphones

Works absolutely flawless on Windows 11, well worth buying if you have issues with Realtek drivers on Windows 11 like I did with multiple BT adapters.This has a Broadcom chipset.

I'd never bought, or even looked for, Bluetooth USB adaptors before buying this. I really had no idea of the likely budget or complexity of such an item. However, I'd decided to get a pair of Bluetooth headphones to pair with my new tablet, and checked to see how difficult it would be to clear my desktop area of another few wires by getting an adapter to pair them with my tower PC as well. One website I spotted had an idiot's guide to pairing Bluetooth devices to PCs, and it just so happened that the Bluetooth adapter they'd used for all their tests with phones, headphones, speakers etc was this one. It almost seemed like a given to them - why would you use anything else?Based on that, plus the lower than expected price, I ordered this.It arrived promptly and was so easy to install and pair with the headphones (and a tablet and a phone). I'm using it with Windows 10, and I've tried it plugged in to both USB2.x and USB3 sockets. It's been working with no interruptions or upsets ever since I got it. Admittedly my use has been at close range so far, so I can't comment on the strength of signal and connection. But it does exactly what I'd hoped for. Very pleased indeed.

Bought this for my old laptop running Linux ( Zorin OS 17 .3). I can now connect to my Android phone and my Bluetooth ear buds. Very pleased with this purchase

Works o.k for Windows 11. Problems with Linux. The instructions gave links to download drivers that are blocked, or contained errors. I was able to get it to work by searching for RTL8716B drivers. Even then it kept disconnecting. I eventually bought a different device which worked without issue.

Arrived a day early, and once it was plugged in there was no more to be done, having downloaded the driver from their website. As soon as you connect something for pairing, windows finds the driver and puts an icon on your desktop for any necessary configuring options applicable to the type of device connected, so you go to your desktop for one click connection & configuring options. I'm very content & happy to have this item.I am taking the opportunity to update this review after having had a unit apparently fail on me. I contacted the makers, who could not have been more helpful, with advice via e-mail. When their first sugestion didn't work. they immediately sent me a replacement post-haste.upon fitting the replacement unit, the light remained on until the drivers finished loading, and then went out. My attempts to see what I could find out from Microsoft, and other user forums revealed that Microsoft do not appear to care if you have problems with your hardware, just upgrade to the latest windows and all your problems will be solved. yeah, right......Back to the manufacturers, who sent right back a further e-mail suggestion, (basically, a full uninstall and re-install) which worked and the unit is sitting in its USB port working nicely. I have a sneaking suspicion that various windows and other third party driver updates may be playing a part in the fun & games. I was running the unit in a windows Vista PC, and could not find out anything specific about the registry settings relating to the Bluetooth software, but there are a number of very helpful websites out there who have what they claim to be the solution to a type 43 errorcode in windows (which is what windows was reporting to me as being the problem, but without any further explanation....)and offers you a free download to scan your system. Of course, the fix requires a licence for the sum of about $100.00 USD. Soooooo helpful, the yanks........The bottom line, is that this little unit will give you great functionality, if you need it in a PC that does not have bluetooth already installed, and do so at a very acommodating price. I can also thoroughly recommend the manufacturers helpfulness if there's a problem.

The firmware is not correct for Linux or a Raspberry Pi. Don't buy this it's not what it says and it is a fair amount of work to update it, certainly do not buy it for Home Assistant by the Asus USB-BT500.

I have had bluetooth trouble on my 2015 iMac for ages first it worked intermittently then in packed up completely.Showing bluetooth not available and no bluetooth shown in system preferences.I avoided using an adapter for ages due to people reporting problems with on Mac's and if you search you find loads of people with the same problem. But this little device has done something Apple couldn't, giving fully functional bluetooth.It didn't come with much in the way of instructions just a little booklet, but it was precise and not much instruction needed.Didn't need any software or drivers just plug in and it immediately found and connected my trackpad. It also stays on when iMac goes to sleep so no problem waking from sleep and connection has been solid.It has a small flashing blue light to show it's working.I highly recommend the Kinivo BTD-400

plugged it in, had to install a bluetooth component to pc, (didnt have one installed), then boom, it connected to my hifii, no problem, although a note of caution, i havent been able to connect it to my phone, says its connected, but cant send files via bluetooth to the pc from my phone, will try and figure it out
