Problems with the simultaneous operation of the mouse + bluetooth 4.0 headphones. How to decide?

Question

Bluetooth

Good afternoon,
Today I was surprised to find that the bandwidth of bluetooth 4.0 is not enough for the simultaneous operation of the keyboard + mouse + headphones (although I suspected yes).
I tried to connect to Nokia 8 with 5.0 and it works fine there.
Actually the question is that I did not find any 4.2 or 5.0 adapters, only network cards on aliexpress, which are not credible.
Several questions at once:

• Is it possible to use multiple blue tooth 4.0 adapters on 1 PC (win10)?
  
• Is it possible to buy a 5.0 adapter/network card (and where?)?
  
• I did not find real numbers of 4.2 adapters, as well as their availability. 4.2 will fit?
  

Answer 1

Hello everyone, after more than a year I found a solution to this problem!
In my case, the problem was the background from the motherboard, which jammed the signal. I discovered the problem after buying a new motherboard with built-in 5 bluetooth and a completely similar problem and .. macbook with the same problem.
When connecting a whistle through a usb extension cable or corny into the front connector of the system unit, I get the perfect work of 3 devices at once.
This solution works accordingly for all devices, including macbook.

Answer 3

How I solved the problem (besides turning off the microphone, changing the burst mode and sample rate): On the taskbar in the tray of hidden icons, right-click on the bluetooth icon, select open options. In the Bluetooth settings, select COM ports, add. You choose outgoing, in the port devices you specify your bluetooth earpiece. After you add empty on entering. In the device manager, under Bluetooth + High speed Adapter \ properties \ power management \ uncheck the box to turn off.
You need to connect headphones first, then a mouse (after checking the sound in the headphones), otherwise the COM ports will get confused.
For more fine-tuning, then go to Device Manager \ COM and LPT Ports \ select the assigned port \ right mouse button \ properties \ port settings \ and set your preferred settings (it is recommended to change if something does not suit you)
