Hi Matheus,
again, I'm replying in public (cc: ibr-dtn(a)ibr.cs.tu-bs.de). Please do
so, too, since I won't be able to reply the next two weeks...
Maybe you should have at first a look at the DTN architecure. In order
to transmit data, you need to define on which interfaces nodes will be
able to exchange data. These are the "convergence layers".
What you will need in your ibrdtnd.conf is something like this, for all
embedded platforms:
-----------------------
#routing:
# use prophet/epidemic/flodding instead of
# "default" to be able to transmit bundles from
# the banana pi to the raspberry via BB
routing = prophet
#could be lo, to allow connections only from the loopback interface
#api_interface is used to define where applications connect to
#the local dtnd
api_interface = any
#which interfaces to use
net_interfaces = wlan0 wlan1
#wireless interface wlan0:
net_wlan0_type = tcp #we want to use TCP as protocol
net_wlan0_interface = wlan0 #listen on interface wlan0
net_wlan0_port = 4556 #with port 4556 (default)
#wireless interface wlan1:
net_wlan1_type = tcp #we want to use TCP as protocol
net_wlan1_interface = wlan1 #listen on interface eth0
net_wlan1_port = 4556 #with port 4556 (default)
-----------------------
This part of the config file could be used on the embeded platforms,
maybe you have to adjust the interfaces for the node with internet.
Best regards and good luck,
Stephan
