struct.unpack issue and no connection for a longer time

[techn0tr0ll]

hey there

i'm using your repo to control my nuki lock via bluetooth, which basically works quite good via your test commands `python . --unlock' but if i want to run the server, there are some issues...

Just want to mention, that the server itself is alive and i can talk to the endpoints like '/info' but nothing else, because i need the nuki_id for the api calls , which cannot be retrieved until now.

Do you have any idea?
