def set_packet_timeout (address, timeout):
n = round (timeout / <NUM_LIT>)<EOL>write_flush_timeout (address, n)<EOL>
Adjusts the ACL flush timeout for the ACL connection to the specified
device.  This means that all L2CAP and RFCOMM data being sent to that
device will be dropped if not acknowledged in timeout milliseconds (maximum
1280).  A timeout of 0 means to never drop packets.

Since this affects all Bluetooth connections to that device, and not just
those initiated by this process or PyBluez, a call to this method requires
superuser privileges.

You must have an active connection to the specified device before invoking
this method
