BTD400

Having experienced a couple of Class 2 devices which lost connection with just my hand or a coffee table in the way, it was great to find this device can easily go effortlessly through an internal brick wall. I don't think this is clear enough in the device description, but the Broadcom chip set is Class 2. I also found that I can connect to all my BT devices, phone, Palm PDA and Bluetooth audio adapter. Not the case with my previous dongles. The software was slightly problematic. I had forgotten that with the Widcom/Broadcom stack you must not plug in the dongle to start with or even when asked, which results in the dongle not being detectable by the software. Despite this Windows XP was perfectly happy, recognising the device in Device Manager and reporting no problems. So I had to remove the sofware and re-install, plugging the dongle in when it had all finished. Windows then completed the process and all was well. Its about time Broadcom updated the manual to reflect this problem, which has been around for years. Incidently I had downloaded the latest update from the Broadcom website, but found it impossible to use this at the outset, because it expected the dongle to be installed already. So I used the version 5.6.0.7700 on the supplied CD. I am still on this which surprisingly is a bit clunky, so should perhaps upgrade. However not knowing what the latest version is like puts me off. However this issue shouldn't put anyone off the device which always has a good solid connection to many devices.

Great and works like a charm. I want to write this review though for a simple reason. Basically this device just like any other bluetooth usb adapter will suffer from interference from USB3 devices. I had no idea this was possible or existed but it does. Google the subject and you will get confirmation. It took me a long time to work this out and there isn't that much knowledge on this subject it seems so I thought its really worth confirming this here for others. What this means is that if you plug this adapter into the front of your computer and next to it have a usb3 socket and then sometimes plug something into that which works at usb3 speed (say just a simple usb flash memory stick) you will probably find that your devices powered by this usb bluetooth adapter suddenly degrade massively in performance. I use my adapter solely now for a quality MS mouse and it works 100% of the time until I plug a usb3 flash stick in next door to it. This problem is worst when the usb3 device is very close to the source transmitter of your bluetooth signal (ie this device). If you have a few ports on the front of a PC case or next to each other on a laptop obviosuly the problem is as worse as it can be as the devices are right next to each other. To get around the problem and to carry on using my fast usb3 flash stick without making my mouse inoperable I purchased a usb extension cable and now plug my bluetooth adapter into the end of that, about a meter away from the location on the front of the PC hidden behind my monitor where it used to reside. So to confirm, if you have this problem, the cause is an inherent issue between USB3 and bluetooth. Leave a comment why not if this helped you!

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.

Never tested on Windows/Mac as not interested in that. I purchased this for the purpose of getting my bluetooth aukey earphones working with Teams and Zoom on Ubuntu 22.04. Simple plug and play for Ubuntu(?). Well ubuntu 22.04 found the adapter without issue. Connecting my earphones to it - no problem. I had to go in and change the sound setting to be aukey for speakers and mic. first test: played iplayer thru firefox - no sound. even though the sound bar was telling me that sound was being played by iplayed I could not hear it. Played around with all the sounds setting - yes the test worked I could hear the drip/bark test sound. iplayer nope. 2rd test - the self test with TEAMS. - could not get to hear the self test and mic never recorded anything. checked in the sounds tab in ubuntu - I could hear the drip/bark etc 3rd test - tried zoom. setup a meeting with my iphone as the other user. Could never hear any sound from the aukey earphones and mic sound was not heard on my iphone. - checked the sounds tab in ubuntu - I could hear the drip/bark etc 4th test - played a movie thru vlc. Had to select correct source on vlc - this worked Summary - never got the mic to work. Only got the sound to work with vlc and not zoom or teams. I repeated the above tests with another set of bluetooth earphones and got the same results. So it wasnt the earphones. I did not test the file transfer. I did get it to pair with an iphone/ipad but did no more testing than that. For my needs - this bluetooth dongle fails. I returned it and purchased a usb headphone.

Te duur voor wat het maar is. Kocht daarna een bluetooth dongle van €15 en die werkt even goed, ook onder linux.

working great off the box on my ubuntu linux

Nach 4 Versuchen (Hama, CSL, ...) nun endlich ein Dongle, der Folgendes auf Anhieb macht: - einstecken in Windows 8.1 PC und selbstständige Installation (Bluetooth Icon erscheint in der Taskleiste) - Koppeln mit Dualshock 4 Controller klappt problemlos (PS Button und Share-Button gedrückt halten, bis Controller weiß blinkt) - das DS4Tool 1.2.2 erkennt den Controller sofort. yay. Endlich gediegen vom Sofa über PC und Beamer daddeln!

Su PC, ho connesso mouse e tastiera bluetooth in un baleno. Purtroppo, a me serve sul nas, un Qnap tvs-673: ebbene, funziona con l'audio, ma non con mouse e tastiera. Questo perché Qnap non supporta l'emulazione HID bluetooth via software. Pertanto, il prodotto è validissimo se collegato a un dispositivo con supporto al bluetooth via HID. Ottimo come sempre il servizio Amazon.

Tenía mis dudas porque nunca había usado un adaptador bluetooth o un producto de la marca Kinivo, pero ha superado mis expectativas. Lo uso con mis auriculares August EP650B y la conexión es excelente, nunca se corta o se retrasa y puede incluso cambiar de habitación sin interrupciones. Buena relación calidad/precio. Instalación sencilla y bastante rápida.
