Hey,
my problem looks very similar to yours. Basically I am using DemoApp (from samples) and trying to send data from co-ordinator to sensorEB. I have added out cluster command on coordnator and incluster for sensorEB. It show bind successful, but when coordinator sends the packet, it comes out with error (I am yet to sniff). I checked -DPOLL_RATE variable and it is set to 1000. I dont know what am I missing. ??
