I have a Logitech mouse that I can map the buttons with an app when in Light Speed mode, but my wireless Akko keyboard requires the cable to be plugged in to be able to remap the keys. Since the dongle is called “receiver”, I kinda assume it can only receive signals but cannot send them, but that doesn’t seem to be the case with the Logitech dongles.
Many of the wireless devices I’ve had the dongle was really just a Bluetooth adaptor, but the Logitech ones seems to vary.
I managed to find this article on Logitech’s site which lists all the devices except the 27Mhz ones as “bi-directional” so I’d guess that the name “receiver” may be deceptive in this case and that these are actually transceivers that both send and receive signals.
