The bundle protocol requires that the clocks of all nodes are in sync and have a valid timestamp (> 2000-01-01 00:00:00). Fix that and it will work.
Is there a limit in how big are the data packets?
Yes. The protocol limits the size to 2^64 bytes. Additional your platform may limit the file sizes on 32-bit systems this is usually 2^32 byte.
Furthermore, is there any more extended tutorial where the parameters of the configuration file and how to change them according to our needs, are explained in more detail?
There exists the configuration file for the standard dtnd without the UCI wrapper for OpenWrt. This file shows more details on the settings, but does not match to /etc/config/ibrdtn. https://github.com/ibrdtn/ibrdtn/blob/master/ibrdtn/daemon/etc/ibrdtnd.conf
In any case you should first know what you want and then check the configuration options to achieve it.
