This program shows how to set different low power states in XBee-802.15.4 modules * Pin Hibernate (SM = 1): XBee is put to sleep and is wake up by setting a pin high and low * Pin Hibernate (SM = 2): The same as before, but more consumption and faster wake up
Required Materials
1 x Waspmote PRO
1 x Battery
1 x MiniUSB wire
1 x XBee-802.15.4 module
Notes
- The battery has to be connected.
- This example can be executed in Waspmote v12 and Waspmote v15
Code
