This example shows how change the power mode from ON to minimum functionality
Required Materials
1 x Waspmote
1 x battery
1 x 3G + GPS module
Notes
-This example must be mastered by those users who want increase battery life reducing the power consumption of the 3G module
- 3G module must be powered with a battery
- When 3G is in use, interrupts can't be used
