"""
Shows how to receive a file over OBEX.
"""
import lightblue
# bind the socket, and advertise an OBEX service
sock = lightblue.socket()
try:
sock.bind(("", 0)) # bind to 0 to bind to a dynamically assigned channel
lightblue.advertise("LightBlue example OBEX service", sock, lightblue.OBEX)
# Receive a file and save it as MyFile.txt.
# This will wait and block until a file is received.
print "Waiting to receive file on channel %d..." % sock.getsockname()[1]
lightblue.obex.recvfile(sock, "MyFile.txt")
finally:
sock.close()
print "Saved received file to MyFile.txt!"
# Please note:
#
# To use a file through this example, the other device must send the file to
# the correct channel. E.g. if this example prints "Waiting to receive file on
# channel 5..." the remote device must send the file specifically to channel 5.
#
# * But what if you can't specify a channel or service?
#
# If you can send a file to a specific channel - e.g. by using
# lightblue.obex.sendfile(), as the send_file.py example does - then you
# should be fine.
#
# But, if you're just using the system's default OBEX file-sending tool on
# the other device (e.g. "Send file..." from the Bluetooth drop-down menu on
# Mac OS X, or "Send ... Via Bluetooth" on Series 60 phones), it may only
# allow you to choose a device to send the file to, without choosing a
# specific channel or service on the device. In this case, the tool is
# probably just choosing the first available OBEX service on the device.
#
# So if you switch off all other related services, this example's service
# should automatically receive all OBEX files. E.g. if you're running this
# example on Mac OS X, go to the System Preferences' Bluetooth panel: on
# Mac OS X 10.4, go to the "Sharing" tab, and uncheck the "On" checkboxes for
# the "Bluetooth File Transfer" and "Bluetooth File Exchange" services.
# On Mac OS X 10.3, go to the "File Exchange" tab, and for "When receiving
# items", select "Refuse all", and uncheck "Allow other devices to browse
# files on this computer".
