ZEXMTE Bluetooth Adapter for PC 5.1, Long Range USB Bluetooth Adapter 328FT/ 100M Bluetooth Dongle 5.1 EDR, Bluetooth Adapter for PC Windows 11/10/8/7-Bluetooth USB Adapter for Computer/Laptop

Immediately shows up in home assistant. Connects to my Airthings Wave Radon.The Bluetooth built into the NUC I use for home assistant stops working after a few weeks and needs a system reset. Hopefully this fixes that.Update: 2 months solid so far without any connection dropout.

I have a 5 year old HP Envy desk computer that came with a built-in bluetooth/WiFi adapter. I was getting about 10 feet of scratchy range on my bluetooth headphones so I bought this adapter. Installation was easy but making it work was a challenge. At first I disabled the driver and native bluetooth adapter and installed this one and the new driver and it worked... until I rebooted. The old adapter and driver reinstalled, conflicted with this one and I had no or unreliable connection. I almost returned this adapter in frustration.However, I took a deep breath and opened my computer case and went looking for something that might be the built-in. Behind the hard drive and CD drive I found it, a WLAN chip with 2 antenna wires attached. I removed the chip from it's socket and restarted the computer. NO bluetooth (and no WiFi). I plugged in the adapter, installed the driver from the CD and rebooted and my bluetooth devices started working. I can now walk outside, 50 ft away, and still have sound on my bluetooth earphones. I no longer have WiFi but I do have hard wired ethernet so I don't need it. If you need WiFi, be sure to purchase an adapter that has both.So, in my case I had to physically disconnect my built in radio before I could get this adapter to work. I suspect you will as well if you have one. However, I am now 5 star happy with my bluetooth!

The CD that came with it did not work, if you get this do a search for Realtek Bluetooth 5.0 Adapter RTL8671B on google, Or search for "peteristhegreat realtech" that driver worked, but it took a lot of effort to find the driver.

Works with Home Assistant and has great range. There's a sensor 20-30 feet away on the other side of the house from where the Home Assistant hardware is and it never has an issue maintaining the connection.

Terrible. This is a poorly made and presented product.It claims to work with Windows 7.The product I received came with a CDROM disc with software. That's useless in 2023.The paper instructions makes no mention of where to download any software.I determined the product was BT-505, did a Google search for a driver, and downloaded what was hopefully the correct software.The software installed a device called "Realtek Bluetooth 5.0"which is not what I paid for.This device is supposed to be Bluetooth 5.1The software didn't install correctly, with some new devices saying "this can't start".I thought about un-installing the software but there's no listing for this product in the list of "Installed Programs".I tried re-installing the software and it won't let me. It says "There are unauthorized Bluetooth adapters in your system"and then "Realtek Bluetooth" is not installed in your system.Ridiculous.I tried pairing with my headphones. It doesn't work.So in conclusion, this product is worse than the Bluetooth that is in-built to my laptop.I haven't seen a computer accessory this bad in a long time.

Swapped out an old BT4 dongle (with internal antenna) to this BT5 dongle and supplemented a 2.4GHz antenna I had lying around, and now HomeAssistant reliably gets BT beacons from anywhere in the house. This is a huge step up from the BT4 stuff I was using before. Can't recommend it enough.Even before I swapped the antenna it was fairly reliable picking up govee sensors, though the upgraded antenna does seem to have helped with range a bit (mostly due to the fact that it has an SMA cable that I used to get the antenna out away from the rack, which I think was interfering with reception a bit).

I bought this adapter to improve the range of my bluetooth for my headset, but it did not perform any better than the bluetooth radio that is already onboard my laptop.However, if you don't have bluetooth and need an adapter, it is plug and play and stupid easy to use.

I recently received a nice pair of headphones as a gift. Once I found my computer did not have Bluetooth I began researching what was available. I chose this adapter as I knew I would be walking away from the computer occasionally and felt the antenna would provide better flexibility. I plugged it in, and Windows (10) did all the rest. I'm able to go upstairs (within reason) and just about anywhere on the floor the computer is. Very happy with this product.
