[ibr-dtn] IBR DTN on Android not receiving bundles

Hello,

I am creating na application that uses IBR-DTN and testing using 2 cellphones. However, though both cellphones have installed the exact same application, when I click to send the DTN packet only one manages to receive. For example, cellphone A sends dtn packet to B and B receives, when B sends a packet to A, A doesn't receive. I've checked that A and B really send their packages, the problem seems to be on the reception. Does anyone know what might be causing it?

Thanks in advance, Guilherme Rolim
