Works well.
Effective Bluetooth transmitter. Easy to use if you read the instructions. My laptop Bluetooth was terrible. I was using it to transmit sound to a stereo 5 feet away and the audio was terrible. Using this transmitter the audio quality slip great and Im even using it to also support a Bluetooth mouse at the same time with no noticeable lag. Very happy with the purchase.

I am happy to report that everything is working perfectly
Note: This is for the DG40S model, as I bought this for use on a Windows 7 PC. My goal was to find a USB Bluetooth adapter that would allow my PS4 DualShock 4 to connect to my PC without the need for DS4Windows software. Also note that the DG40SA being sold here is clearly advertised as not being compatible with Windows 7, so I didn’t try that one.I am happy to report that everything is working perfectly! Though, as described here and on Avantree’s site, this adapter is NOT exactly plug and play when used with Windows 7 (it apparently is with Windows 10), but it’s close enough! Very simple to get working. Just go to their support site, click the DG40S icon, then look for the link labeled “Latest Driver for Windows 7.” Before you click it, take note that there are also many useful support links here, in case you run into problems. When ready, click the Windows 7 driver link, and you’ll see another new list of more helpful links, many of them with videos outlining the simple step-by-step install process. YOU MUST WATCH A VIDEO OR TWO HERE! It will only take a few minutes, promise. BUT WATCH BEFORE YOU INSTALL! Lol. It’s just a series of left/right/double clicks that are required, takes no more than 2 minutes, but since their interface is so artistically done in a 1982 programming style, you’ll save time if you just watch a vid first. NOTE: ALL STEPS OUTLINED IN THE VIDEOS REGARDING CONNECTION (key words: ALL TWO OR THREE STEPS) MUST BE DONE WHILE THE DUALSHOCK CONTROLLER IS IN PAIRING MODE! To enable this, hold down the center PS button and the Share button AT THE SAME TIME, for a few seconds, until the DualShock’s light starts flashing. This means it’s searching for Bluetooth devices to pair with. You might have to re-enter it into pairing mode if the lights stop flashing. Anyway, before you know it, your DualShock 4 will be connected – with great range, too. Has been working flawlessly after hours of gaming!As it turns out, I needed tech support for something I goofed up on (all that was needed was a restart of a couple things that I somehow missed). I called their support number (conveniently displayed on the main screen of their driver software after installation), and was almost immediately set up with the next tier of tech support via a live, screen-sharing conference! They sent me a link via email that directed me to download the Chrome extension called GoToMeeting Pro Screensharing. Pretty slick/legit extension, nice interface. Also had the ability for me to select specific windows for screensharing, or to just enable the sharing of my entire screen. Anyhow, a couple people on the phone walked me through a couple steps I somehow goofed up on (follow the steps above and you’ll be fine, lol). They were super helpful and kind. Pretty amazing customer service, some of the best I’ve experienced from any company, no joke.Anyhow, if you’re using this with Steam, make sure you follow online guides how to do it. Also ridiculously simple, just open up Steam, enter Big Picture Mode, click the settings gear button –> controller settings, then make sure the “PS4 Configuration Support” box is checked. You might have to restart Steam, or restart the controller’s Bluetooth connection, but yeah still simple in the end, I was just in idiot mode for a few minutes there…Hope this helps!

So far so good
I recently bought a new bluetooth headset for my work from home job. Turns out the application we use to make calls doesnât like bluetooth very much. I kept randomly losing connection and having to open and close the application repeatedly throughout the day. I came across this usb dongle and wanted to see if it would help having something plugged directly into the computer rather than a wireless connection. At first, it didnât seem like it was going to work. The driver installed on its own, but I couldnât get my work computer to recognize the usb. The security measures on my work computer were just not having it. But after I couldnât get it to connect initially, I left everything plugged in, turned off the headset, and went to bed. By the time I woke up the next day and logged in, I decided to try one last time. Low and behold, the usb lit up blue and everything has been working wonderfully since. If you are having issues with your computer or device recognizing the dongle, try to let it marinate overnight before sending it back lol

This works great: here’s how to get it working on a fussy old laptop
I really *needed* a satellite keyboard for my standing desk. But I had nothing but trouble with my built-in bluetooth…maybe because my laptop dates from 2014, even though it is Win10 now.So this Avantree dongle rescued me.Connecting to this dongle would be easy on a plug-n-play Windows 10 modern PC, but since I am not a geek, and my laptop thinks it has bluetooth but it doesn’t, I had some problems. (Or maybe–per my husband–I just have problems.) Anyway, Avantree was fast to help and guide me through it in no time.The following is what I *think* I did to make it work. IIRC. WIMN.1 Turn off PC’s native bluetooth, if any (Start menu> Settings>Devices)2 Download BlueSoleil software from Avantree DG40S product website and install it on PC. (Don’t accidentally somehow install it twice or the rest won’t work properly and you will have to uninstall both BlueSoleil bluetooth drivers in the Device Manager and try again. Like me.) 3 Right-click the zig-zag bluetooth icon in the system tray (lower right) and select “Display Classic View.” The BlueSoleil window opens.4 Left-click once on the orange globe. That should show the name of your PC in a message box AND in yellow text at the bottom left of the window (such as, “MyPCname: 7 services”).5 Plug the Avantree bluetooth dongle into your PC’s USB port.6 Set your bluetooth-capable device (for me, a keyboard) to pairing mode (see your device/keyboard info for how).7 Double-click the orange globe to search for available bluetooth devices. An icon for your device and its name (“Keyboard”) appears somewhere around the orange globe.8 Right-click on your device icon and select “Pair.” 9 A “PassKey” message box appears showing a 6 or 8 digit number. Type exactly that number on your device (keyboard) and click Enter. (Be accurate but fast: it only gives you a short time to do it.)10 Wait for a message that says “Paired.”11 Right-click again on your device icon and select “Search Services.” Wait for a message that says something like “DeviceName > 1 Services” in yellow text at the bottom left of the window.12 Double-click on the small highlighted icon along the top of the BlueSoleil window that corresponds to your newly-paired device. (For me it was the mouse icon, which represents user interface devices like a keyboard.) This causes an actual connection to be made to your newly-paired device (to my keyboard). You see a ray appear in the BlueSoleil window going from the orange globe (PC) to your device. That means your device (keyboard) is connected (just pairing isn’t enough).BlueSoleil should remember what’s paired during normal use and reconnect automatically. If your device is disconnected, right-click the bluetooth icon in your system tray (it should live there), open BlueSoleil in Classic View, select your device icon, and then double-click the proper icon along the top to reconnect (like the mouse, for a user interface). Doesn’t take long.You can now use your bluetooth device. Your device talks to the Avantree dongle, the dongle talks to the BlueSoleil driver (software), and BlueSoleil talks to your PC. Everybody works together. (Try that in politics.)

Works with Linux
Using Xubuntu 22.04 with XFCE and it was plug and play. On XFCE there is a nice widget that pops up in the Indicator plugin.

Je cherchais une clé USB bluetooth afin de connecter mon nouveau casque audio Sony WH-CH700N, ainsi que mes enceintes Edifier R1700BT sur mes PC dépourvus de ce type de connectivité.J’ai pu testé la clé sur mes 4 PC :- Windows 10 Home 64 bits (PC fixe sur mesure)- Windows 10 Pro 64 bits (PC fixe sur mesure)- Windows 7 Familial 64 bits (Asus X53SD-SX1053V)- Windows 7 Starter 32 bits (Asus EeePC 1001PX)Détection de la clé ultra-rapide sur Windows 10. Détection du casque tout aussi rapide.Sur Windows 7, détection un peu plus lente mais tout aussi efficace.J’ai pu testé mon casque dans l’autre pièce, à plus de 10m, sans problème.Pas de déconnexion jusqu’à présent, ni de grésillement du son ou autre.Le seul soucis constaté est sur le logiciel multimedia Kodi. Mais, j’ignore si cela vient du logiciel, de la clé ou du casque car tout fonctionne très bien pour le reste (sons du bureau, VLC, Firefox, Opera…). Je ne pense donc pas que ce soit la clé.Bref, pour le moment la clé respecte ses promesses pour un prix correct.Je ferai une mise à jour du commentaire si des problèmes de fiabilité apparaissent avec le temps. Sinon, considérez que tout est OK. :-)Je recommande.

L’adattatore USB bluetooth della Avantree corrisponde esattamente a quanto descritto nella pagina Amazon di vendita: è piccolissimo, ha un minuscolo led che ne indica il funzionamento, si configura da solo non appena inserito nella porta USB (io lo utilizzo con Windows 10 64 bit, ma laddove dovessero sorgere problemi è presente un cd con appositi driver) e garantisce una connessione bluetooth pressoché immediata con altri dispositivi (personalmente l’ho provato con uno smartphone e delle cuffie e l’accoppiamento è stato velocissimo).Unico neo: nella descrizione si parla di range operativo di 20 metri, ma sopra i 10/15 la connessione inizia ad essere instabile, ma forse ciò è dovuto alla presenza di un muro di separazione tra una camera e l’altra.La consegna è stata velocissima: ordine effettuato il lunedì nel primo pomeriggio e arrivato il giorno successivo intorno alle 11, davvero eccezionale.Quindi ottimo prodotto, consigliato!!!
