Help Testing FreeOTP + Jelling

Hello Fedoraland!

I recently blogged about an effort to improve multi-factor
authentication with OTPs by sending the OTP code from your phone to
your computer directly using Bluetooth. The full story can be read

However, I'm unable to get Jelling for Linux to work on Fedora at all
with my devices. I'm very keen to see if anyone is able to get it to
work with their combination of devices. Can you help?

Testing instructions are available here in the upstream repo:

If I can get this working on at least one combination of devices, I'd
like to bring it to Fedora ASAP. So your help testing is invaluable!
