Review: Best bluetooth adapter in the market. - Today i have got the chance to use it as it was delivered to me in the morning. And one word which comes in my mind after using it is fabulous. I am using windows 10 and the product works like a charm. I was in doubt earlier that whether it would support windows 10 completely or not but now i realise that i haven't done anything wrong in purchasing it. Believe me guys it detects immediately my soundpeats QY7 bluetooth earphone which i also purchased from desertcart and i have connected few phones also and it is working fully with each and every bluetooth enabled device. The sound is transmitting fluently from my computer to the earphone and the clarity is as perfect as if i am using a wired headphone. So those who are willing to purchase a bluetooth adapter i would say that it is the best in the market. Go blindly and purchase it. You won't regret. The packaging was also good. Prompt delivery by the seller. Thanks.

## Questions & Answers

**Q: Will this device mow my grass?**
A: While it may mow the grass what I'd really like for it to do is give a strong, consistent signal.  To identify the specific item it is pairing to and not just to phone 1, phone 2, etc.  To make pairing to my computer easy so one doesn't have to go to the control panel every time and turn off this or that in order to use the headset.  Does it do any of that???

**Q: does this work on linux**
A: This was a little tricky but not too bad.. you have to get a file and you may have to modify the last part like i did had to
First i install blueman via sudo apt-get install blueman
sudo wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd -O /lib/firmware/brcm/BCM20702A0-0a5c-21e8.hcd
sudo wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd -O /lib/firmware/fw-0a5c_21e8.hcd
sudo modprobe -r btusb
Still was not working...so i ran command dmesg in terminal and looked at the failure message . It was very close but mine said it could not find BCM20702A1-0a5c-21e8.hcd (notice the top A0-0a5c-21e8.hcd) so i ran a symbolic link to fw-0a5c_21e8.hcd.

sudo ln -s /lib/firmware/fw-0a5c_21e8.hcd /lib/firmware/brcm/BCM20702A1-0a5c-21e8.hcd
After this i was able to get the bluetooth manager to add the new bluetooth speaker

**Q: How many devices can it support at a time? Can I send/receive files via bluetooth while using my bluetooth mouse using the same bluetooth adapter?**
A: Dear Raymond, Thank you for your questions regarding our BTD-400 Bluetooth Adapter. The BTD-400 can be connected to any number of devices. In your specific set up, you should be able to send/receive files and use your mouse as the profiles use by each device within Bluetooth are different.Please contact us at support@kinivo.com if you have any additional questions.

**Q: Can I use this dongle to link to a bluetooth headset, for music? Here is the product I'm thinking of http://www.amazon.com/LG-Electronics-HBS-700W-Wir**
A: I use this dongle on my computer with an LG 730 bluetooth headset and it works great on music, videos and streaming Netflix. Ive not had an issue with playing anything.

### ⭐⭐⭐⭐ Excellent Bluetooth Adapter
*by V***H on 19 January 2017*

Make - The look of the product and the feel of the plastic on top is good... not cheap, compared to other Bluetooth dongles. Range - Its standard as they have mentioned in its features.(My Experience 6 meters for portable sound bar in straight line after that sound is crackly...for mobiles n headphones its good to go upto 10mtrs.) Price - Its worth the price this sites offer.(Rs.649 on amazon) Compatibility - If you are looking for dongle that runs good on windows 10 then this device does it. I had one dongle earlier running on windows 10 and connected portable sound bar to the system, after few mins. sound use to go blank all of a sudden, then I had to do few tricks to again listen to music, thought of changing the dongle and found this one, I ordered and plugged the device in USB 3.0 jack and since then all Bluetooth devices connect to the dongle in an instant, without any driver installation on windows 10 it connects just good... I would recommend It.
