Is it possible to wake up XBee end device with input (high) from sensor? According to documentation:
"When the device asserts (high) Sleep_RQ, it finishes any transmit or receive operations and enters a low power state."
But in my case i need inverse logic. Sensor (e.g motion sensor) setting it's control pin to high when motion detected.
It is not possible to invert the logic of the XBee itself. But of course you can connect an inverter (NOT gate) to the pin. This can be as simple as a transistor and two resistors, but if you want to save energy, have a look at the CMOS inverter type or special low power components.
