## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Superb product but maybe overpriced.....
*by N***B on 23 April 2025*

We bought this in 2014 for Rs.599. It used to be on my Windows 8 all-in-one desktop. Now, as the bluetooth option has completely disappeared without a trace from my laptop, I'm using this and it's perfectly fine now. But, it costed Rs.600, 11 years ago!😁

### ⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Only dongle that works perfectly with an Xbox One Bluetooth controller
*by H***I on 10 March 2019*

Long story short: buy this if you want a headache-free experience with a Xbox One Controller.Practically every bluetooth dongle listed on Amazon uses Qualcomm's CSR8510A chip - with drivers last updated in 2012. Now, the date wouldn't be much of an issue if the damned chip worked with an Xbox One Controller - the latest one that has bluetooth built-in. I tried two different cheap models, and both struggled to get connected to the controller, and would NEVER reconnect - necessitating a full disconnect and re-pairing. Painful.This dongle uses Broadcom's BCM20702 chip, and it works flawlessly with the Xbox One controller (with Windows' default drivers). I'm also using a Logitech K480 keyboard simultaneously and everything works A-OK. Connecting was fast, and everything reconnects in what feels like a second. This is ~4X as expensive, but that's totally worth it, because the alternative just doesn't work properly.
