I have found these 'dev-ttyHS99.device' and 'hciattach.service' in your repo.
What are these for?
Do I need them?
If yes, where from I can get the '/usr/sbin/hciattach' program/script what the mentioned in the 'hciattach.service'? I didn't find 'hciattach' on the phone either in your repo.
Thank you.
