The Xbee Module is connected to a microcontroller, and it configures and associates correctly with other devices.
I setup the Xbee Module to Sleep Mode 1 (ATSM1) correctly, and then drive the Pin 9 (Sleep_RQ) HIGH to enter sleep mode. The Xbee Module enters Sleep Mode (indicated by Pin 13 = LOW), but the current consumption only goes from about ~50mA to about 27mA. If I drive the RESET pin LOW (pin 5), then the current goes to what the datasheet speceifies (<10uA for SM=1). However, I don’t want to reset the Xbee Module, to avoid forced reassociations.
The question is:
- What needs to be done to reduce the current consumption in Sleep Mode to ~10uA, without having to keep the Xbee Module in Reset?
