The docs (https://ultimatehackingkeyboard.com/manuals/dongle) suggest that once you start up Agent and plug in the dongle, you should just be able to pair the keyboard directly. But when I followed these instructions, it prompted my to plug the keyboard in via USB-C cable. It then prompted me to pair the device, but when I disconnected the cable, it no longer worked. I tried switching connections back and forth with no luck.
I’m wondering if this is related to this issue which I also ran into with BLE pairing: BLE pairing on v14.0.0
The connection to the dongle no longer worked. The keyboard only works when connected over USB. While connected, I could see that the connection to the dongle was created and showed up in the set of listed connection options, but when I tried switching to that connection, the computer with the dongle connected was not responding to it at all.
I linked to that related post as it appears this and similar issues are occuring for others with firmware v14.0.0. I can’t use the dongle or BLE at all with my keyboard. Only usb seems to work. I have not tried reverting the firmware version yet as I had trouble just getting v14 installed on both halves in the first place.
I’m frankly frustrated as this keyboard seems very much not ready for general use, which was not at all obvious on the site.
