I bought a CSR V4.0 Dongle for my PC which runs Window 10 64 bit system. I've manged to hook my new Bluetooth capable 3.0 mouse and it runs very well. My problem is I have a Penna Key board with 4.3 Bluetooth, which won't connect. What am I doing wrong? I suspect I may've bought the wrong type of Dongle

Mouse = Bluetooth 3.0


Dongle = Bluetooth 4.0


Keyboard = Bluetooth 4.3 (or do you actually mean 4.2)


While backward compatibility, e.g., 4.0 supports 3.0/2.0/1.0, is incredibly common I have yet to see forward compatibility, e.g. 4.0 supports 4.3, exist.  Sometimes, and this appears to be one of them, it need not be a major release number difference to cause issues with compatibility.


The dongle (or internal card) to which all peripherals will be paired should always be running the Bluetooth protocol that is at least as recent as the one run by the peripheral with the most recent protocol.
