Sleep feature
The recommended approach is to use one of the available sleep configurations such as the Pin Sleep
feature (SM=1) or sleeping through MicroPython (xbee.sleep_now()). When the module has gone to
sleep and the SLEEP pin (pin 13) is low, power may safely be removed.
1. Initiate sleep: Assert SLEEP_RQ
2. Wait for sleep state to be entered: SLEEP pin (pin 13) low.
3. Power off the device.
Airplane mode
Change the XBee configuration to use Airplane mode (AM=1). This puts the XBee into a safe state for
shutdown.
1. Set AM=1.
2. Apply configuration change.
3. Wait 30 seconds to allow time for shutdown to occur.
4. Power off the device.
