attendance system in pybluez
I want to write a program to help my teacher to take attendence. There are 300 students in a big room,everyone has android phone. I have matched them with my pc in win7 . when all of them seated on the classroom, import bluetooth nearby_devices = bluetooth.discover_devices(lookup_names = True) print(found %d devices % len(nearby_devices)) The function can discover all of them ? 300 bluetooth mac address? can i search for a given bluetooth mac? blue_mac=[] (i can write it in a list in advance,it is not blank,full of strings) for add in blue_mac: print(bluetooth.seacrh_given_mac) #result is true or false Is there a function to run? -- https://mail.python.org/mailman/listinfo/python-list

Re: attendance system in pybluez
in the http://homepages.ius.edu/rwisman/C490/html/PythonandBluetooth.htm *Discovery* The address and name of enabled devices within range can be discovered by other Bluetooth devices. Discovery can take some time to complete, given that radio communications is unreliable. The following displays address and name of all enabled devices nearby. from bluetooth import * print performing inquiry... *nearby_devices = discover_devices(lookup_names = True)* print found %d devices % len(nearby_devices) for name, addr in nearby_devices: print %s - %s % (addr, name) performing inquiry... found 2 devices Ray's Nokia - 00:12:D2:5A:BD:E4 Ray's MacBook - 00:1E:C2:93:DA:6F On 8/9/2014 4:53 AM, Steven D'Aprano wrote: luofeiyu wrote: I want to write a program to help my teacher to take attendence.

I have matched them with my pc in win7 . when all of them seated on the classroom, As soon as I learned someone was using bluetooth presence to determine I was in such a class -- I'd turn the bluetooth feature off! And if attendance was part of your grade? Actually, I agree with you and Steven that the premise that all have an android phone, with battery charge, turned on, with bluetooth enabled, is a bit dubious. At the Univesity of Delaware, students buy a 'clicker', about $20, with an ID (I presume) and a few buttons for answering pop quizzes. I can only guess that they use bluetooth, but with extremely limited function and probably no writable memory, power draw is minimal and hijacking not an issue. -- Terry Jan Reedy -- https://mail.python.org/mailman/listinfo/python-list
