I did some further reading and I made a wrong assumption based on what
I know about wifi. bluetooth doesn't stay on one channel but hops over
the 79 channels at 1600 hops per second. The higher protocol versions
thereby prefer the channels with less interference. So normally
interference shouldn't be a problem. And as far as I can find the same
goes for the RF dongles. So one dongle in stead of two should be
better. Also I found that Bluetooth in general suffers more from
interference then the RF based mice and keyboards. Third I found that
a close by USB-3 cable often gives interference on Bluetooth. So if
your mouse/keyboard dongle was in a usb-3 port?? It could be it wasn't
the dongle but the usb.
