Solved! RF keyboard to Galaxy S9+ possible

May 2, 2018
Is there a method to connect an old 2.4 GHz RF keyboard to the S9+?

Specifically, we have an Adesso WKB-3000 that we used to use with a mini computer. Dongle and computer are long gone. After reading about the capability of plugging a USB keyboard into the S9+, I thought I'd give this board a try.

The keyboard is RF to its dongle. Can I point the phone to this in some manner, a generic app that would mimic the original dongle? It would be easiest to just buy a modern BT keyboard, but sometimes you just want to try a thing.
