Cron doesnt run specific .py file

Question

I wrote a code in Python to change Bluetooth Low Energy information. If I write for example python beacon.py 12 12 major of BLE advertised data will be 12 and minor will be 12. When I run it using terminal is fine however in the crontab -e doesn't work. I tried running another python program (file creation) and it ran. So I am confusing with the problem anybody has any ideas?

import os
import sys

value1 = int(sys.argv[1])
value2 = int(sys.argv[2])

if (( 0 <= value1 <= 65535)and(0 <= value2 <= 65535)):
    def int_to_hex(n):
        str = "0x{:04x}".format(n)
        str = str[-4:]
        [str[i:i+2] for i in range(0, len(str), 2)]
        str = ' '.join([str[i:i+2] for i in range(0, len(str), 2)])
        str = str + ' '
        return str

    Major = int_to_hex(value1)
    Minor = int_to_hex(value2)

    print 'Major (in hex): ' + Major
    print 'Minor (in hex):' + Minor

    sudoPassword = 'raspberry'

    command = 'sudo hciconfig hci0 up'
    p = os.system('echo %s|sudo -S %s' % (sudoPassword, command))

    command = 'sudo hcitool -i hci0 cmd 0x08 0x0008 1E 02 01 1A 1A FF 75 00 02 15 E2 0A 39 F4 73 F5 4B C4 A1 2F 17 D1 AD 07 A9 61 ' + Major + Minor +'C8 00'
    p = os.system('echo %s|sudo -S %s' % (sudoPassword, command))

    command = 'sudo hciconfig hci0 leadv 3' 
    p = os.system('echo %s|sudo -S %s' % (sudoPassword, command))

    #apple: 76 (d) ->  00 4c -> 4c 00 
    #samsung: 117 (d) -> 00 75 -> 75 00

    #prefix (9 bytes)
    #uuid 16 bytes: (e20...)
    #major 2 bytes
    #minor 2 bytes
    #tx power 1 bytes   

    print 'Success!'

 else:
     print 'Please specify major and minor values to be between 0 and 65535'
