I bought this controller https://www.amazon.de/...075YBP8LT/
he works on the switch so far without problems
on the pc this can also be used by cable
weis a random as I can use the synonymous with bluetooth or with the magic ns without cable s.PC?
To my knowledge, the Nintendo Switch uses normal Bluetooth technology.
The controller could also run with Bluetooth dongle on the PC. The manufacturer does not officially support this.
Since you already have the controller, I would grab someone with some reasonably current laptop with the same operating system as your PC, since there's usually a Bluetooth receiver built-in. On the laptop would first test whether the controller is also recognized by cable (to rule out misdiagnosis) and then try a pairing via Bluetooth.
If it works, I would get a USB Bluetooth dongle for the PC that has the same specification as the notebook's Bluetooth and then hope it works again. Even then it is still possible that the next Windows update or upgrade destroys the whole thing again.
It is also possible to program your own Bluetooth stack, which allows operation and specific communication features of the Nintendo Switch on the PC and specifically adapts the coupling process. This, however, exceeds my abilities and probably yours too.
I already have a USB Bluetooth dongle
the problem there's the controller is not found in windows via bluetooth
As I read, the controller is only found on the switch, if you had previously connected it with a USB cable.
Therefore, I'm afraid that there's a special login process that is not implemented on the PC.
I thank you anyway
