when I send data to sleeping End Device from Coordinator，the following situation has occurred.
0x735C is the sleeping end device,the 0xABBA is a router node .0xABBA should send data after the 0x735C data request,but 0xABBA is send data directly.0x735C is sleeping now ,so it cannot receive 0xABBA data.
When the above happens，I restart all devices ，but it's the same as before.
How to fix it ??? What happened in this situation???
Please help me !!!
