# mass-blue is a bluetooth mass-sending tool for files of any kind.
# It's useful for commercials or mass-deploying software.
#
# It uses hcitool to search for devices, then uses sdptool to get the correct
# channel and then does an OBEX Object Push. The ussp-push tool does not always
# get the correct channel on a "Sony Ericsson K610" and maybe others; I have no idea why.
#
# You can use the "list" functions (-o/-F) to only send a file once to every user;
# which I strongly suggest! Bombing really doesn't make sense.
#
# The script was successfully tested with an SGH-i300 and an K610.
