The Egg Ache Institute's bluetooth sign-in

Recently the entire Institute of the laboratory to the people to adopt a mobile phone Bluetooth check-in mechanism, everyone needs to install an app on the phone, and then manually click the check-in and leave button to count each person's daily work time, it is a anti-human design, in the spirit of just hacking for fun, ARP sniffing the mobile phone sent to the packet, learned that and the server is through the TCP communication, but also get the format of the packet, so started to write scripts, to achieve automatic registration.

The code is as follows, implemented with a PHP socket:
