xBee communication problem

0,0 and 0,1 are lousy addresses. Use something else.

0,0 means broadcast to the world, which is NOT what you want to do.

  addr64.setMsb(0x0013a200);
  addr64.setLsb(0x41255DB2);

Why are you telling the coordinator to talk to this address, when you say that that is not the address of the end device?
