My sequence is :
My coordinator and my end device are ON (turn on). My end device work with a battery (3V).
When I press the switch (end device) the LED of coordintor turn on. And after the end device enters in sleep mode.
After that I turn off my coordinator. If I press my switch, the of coordinator turn off. It's normal.
But my end device don't enter in sleep mode. Why my end device don't enter in sleep mode when my coordintor is turn off ?
