Linux and Paper Pro request + testing

Hey, great work!

I'd love to help test this for support on Linux hosts, and with paper pro.
I have both, will test here report back :)

For instructions, suggest using venv instead on modern linux systems:

python3 -m venv venv                                                          
source venv/bin/activate
pip install -r requirements.txt

Requirements install just fine on Ubuntu 24.04, program launches fine

Also nice that your app supports ssh key instead of password, if the password section is just left blank

Works great on the paper pro!
Paired just fine with my Keychron K9P-H3

However, after power cycle, now failing to connect.
Even re-using your app, still unfortunately fails to connect:

BTW the app also seems to disconnect after a few minutes, is this expected? It always reconnects fine.

Restarting the keyboard still allows for re-connection, after about ~15 seconds of pairing process.
It seems to be an issue with restarting the Remarkable that breaks the pairing process.

SSH into the Remarkable, and following along with bluetoothctl showed that the keyboard was not yet "trust"-ed.
This seems to help, but still hit or miss.

These are the notes I have on bluetooth in general:

modprobe btnxpuart
bluetoothctl show

bluetoothctl
power on
scan on
pair <mac>
connect <mac>
trust <mac>

SSH forcing a reboot seems to help sometimes as well, but again not consistently...
