@Solla-topee, Hi there.

 

Maybe I didn't explained it correctly, I have a Asus Laptop at work with built-in Bluetooth and my Samsung connects there without problems, in my PC at home is where I have the problem, I bought the UB4A adapter and installed it without problems (and yes, the blue icon appears) but only the PC recognizes the smartphone, it's kind of weird because the smartphone is listed on the Bluetooth devices but if I try to connect the other way around (Smartphone to PC) I get the message "impossible to connect"...that doesn't happens on my laptop, the connection appears active on both devices (I also have a smartwatch and at work the smartphone has the two devices listed as connected).

 

I'll try to take some screenshots of the connection on the smartphone on both machines so you'll understand it better.

 

Thanks for the reply.

@Solla-topee , Hello again.

 

Let's see if we can finally figure this out...

 

I'll start by the Laptop specs I use at work (I upgraded it a bit):

 

• Asus K550JK with Windows 10 Pro x64
• Intel Quad-Core i7-4710HQ@2.5GHz (Turbo up to 3.5GHz)
• 12GB DDR3@1600Mhz
• 1TB SATA III Samsung SSD
• HD Graphics 4600 + NVIDIA GTX850M 2GB
• Wireless 802.11ac + Bluetooth 4.0 (Dual band)
• LAN 10/100/1000 Mbps
• and more....

 

And my home PC specs (bought it 1 year ago):

 

• Chip7 Do it v6.2 Limited Edition with Windows 10 Pro x64
• Intel Octa-Core i7-9700K@3.60Ghz (overclocked and reconfigured, all 8 cores running@4.9Ghz)
• Asus Z390-Plus TUFF Gaming Mobo
• Asus Nvidia RTX 2060 6GB O.C. TUFF Gaming
• 16GB DDR4@3200MHz ADATA CL16 XPG RGB SPECTRIX 
• 512GB Mv.2 ADATA SX8200 SSD
• 480GB SATA III Kingston A400 SSD
• LAN 10/100/1000 Mbps
• and more (no built-in WiFi or Bluetooth, but I already have a Asus WiFi card with an antenna to install)....

 

My Smartphone it's a standard 2019 Samsung Galaxy A7 DS (SM-A750FN) with 4GB/64GB and Android 10.

 

Well, now the screenshots...this is my Samsung display showing the paired and connected Bluetooth devices on my Laptop at work (MIGUELABREU-PC and the HUAWEI WATCH), the language it's in Portuguese but I think it's easy to identify the respective status on-screen (Portuguese text "ligado"=turned on and "ligado para chamadas"=turned on for calls):

 

 

 

This is my Samsung display showing the Bluetooth devices on my PC at home (MADLABS01) with the UB4A adapter (Portuguese text "impossível ligar"=impossible to connect):

 

 

BUT...if you go to the Windows Definitions and check for paired Bluetooth devices, this will show up:

 

 

Even on the old Control Panel on "Devices and Printers" it shows up paired:

 

 

It's really strange...I sent the Samsung screenshots I took using the UB4A Bluetooth adapter connection with my PC at home and it works, so how come on the smartphone side it won't assume that is paired up and connected?? It seems it's working well on sending/receiving data but it won't establish a connection for the telephone calls or SMS notifications an text...

 

Stranger, on the Asus Laptop (with built-in Bluetooth, exactly the same version, v4.0) everything works wonderfully, if I want I can use the Laptop camera and microphone to receive/make calls or videocalls and use the keyboard to write SMS, it just doesn't make any sense why the UB4A adapter is not working in the same way!

 

Two days ago I noticed on Device Manager that I had two devices that required further installation with a question mark icon, both related with the adapter! one device had "SMS/MMS" indication and the other had "Ic_Service" so I went to the properties and copied the hardware Vendor/ID, then I googled it and found the missing drivers! I installed them and both device errors disappeared, a new device appeared under the Bluetooth expansion menu and on the properties but it still won't work as it should! (today after I turned off and turned on again the computer, the "Ic_Service" device error appeared again on Device Manager...witch didn't happened when I just did a reboot when I installed the drivers).

 

Resuming...what the hell is happening with this adapter?? In the "Quick Guide" manual it says the adapter is a "Plug and Play" device and that it doesn't needs any kind of extra drivers installation (except for Windows 7, if I'm not mistaken)...so, whats the problem here?? A six year old laptop detects everything and a one year new PC has problems with an USB/Bluetooth adapter that is practically new??

 

I really need help on solving this "situation"... 

 

 

Thanks in advance!

@Solla-topee . Hi there.

 

 

Thanks for the tip regarding the mail, I did received that mail you mentioned but it went straight to my SPAM folder and I didn't noticed it...anyway, I already replied it (I just hope it isn't too late).

 

 

Regarding the issue....I've tried everything...unpaired everything, disconnected everything, deleted the device history connections and retried to do everything from the start...I keep getting the same kind of "response", the UB4A USB Bluetooth adaptor is recognized and installed without issues, the PC does recognize the the smartphone and it does pair with it but the only thing I can do it's send and receive files between devices, if I try to initiate or do anything from the smartphone side regarding calls or whatever I keep getting the same message "impossible to connect" (and in Device Manager there are two devices popup as not recognized, I guess it has something to do with the communications protocols between the smartphone and the PC because on the laptop those two devices do not show up as unrecognized)....

 

I need a break to put things on perspective...I've been a little busy at work (I'm a IT Tech and I spend all day around computers so when I get at home I try to "switch off" a bit) but I'll try to manage my time and compile some more info regarding the unrecognized devices and the Microsoft App situation regarding the calls and text messages.

 

This situation it will be followed up by mail from now on or should I keep posting my responses here anyway?

 

 

Cheers!

@Mike80 I am also using samsung mobile and faced the same issue like unable to send the files /pics/videos from mobile to PC(Win10). But Mobile device has been successfully paired successfully in PC but unable to connect via phone.

 

But i just found one solution, it may help to you. 

 

I've noticed in WIN10 settings. 

 

1) Goto - Settings

2) Click - Devices( Bluetooth & Other options) -Hope you already pair the mobile devices in PC using ADD Bluetooth or other devices option. Technically, you mobile is already paired with PC ( As per my knowledge)

3) In the same page - under "Related Settings" - You can see " Send or receive files via bluetooth" option

4)Click - " Send or receive files via bluetooth" - Also click the option called "Receive files" . Once click the "Receive files" option , you are able to send the files from mobile to PC.

 

It may looks like lengthy process. But it is working fine for me.

 

If anyone knows any other process, let me know.

 

 

Thanks!!

 

 

@sriktm, hi there.

 

I never had a problem in sending or receiving files between the two devices, for that I just go to the Bluetooth icon on the task bar, click over it with the mouse's right button and select "send file" or "receive file" (another way to do it is just choosing to share a document or a photo on a app and selecting "share to another device", this way also works).

 

My main problem was that I couldn't get to connect my smartphone to the PC to make calls like I do on my laptop at work that has built in Bluetooth. My Samsung smartphone did paired up with my PC but it wouldn't connect to make calls inspite me having the Microsoft app installed on the phone and it being associated with my windows account. After sometime I just gave up...

 

But two weeks ago or so Microsoft released an update to the Windows "Your Phone" app, and suddenly everything started to work correctly! Now, if I wish so, I can make calls on my PC using my Headset (or make video calls using a camera) as I already did on my laptop at work (I don't know if you have this kind of setup but you can also reply to text messages, see notifications, manage pictures and so on, all on your monitor!).

 

Cheers!
