A power state transition will trigger an event via the Event Queue UAPI so any application specific power logic can be added.
Additionally, there is a callback when preparing to ender Full Off mode for application specific shutdown preparation.
Power Management Type
To verify the power management transitions to different states it is important to select right power management type, either
power measurement via voltage or by state of charge. By default, it's set to
POWER_MEAS_TYPE_SOC i.e., 1. For more details refer UAPI document Section 21.4 Power Management Type.
typedef enum
{
POWER_MEAS_TYPE_VOLTAGE = 0,
POWER_MEAS_TYPE_SOC
} power_meas_type_enum;
AT+PWRMEAS=< power_meas_type_enum> Queries and selects between voltage or state-of-charge-based power
management.
Manual Power States
If desired the power UAPI can be set into a manual mode allowing for power state transitions to be triggered manually via AT
command for API call. Manual power mode must be enabled before this feature will work. Once in manual mode, all automatic
state changes are disabled, and only manual state change requests will cause state transitions.
1. To enable the manual transitions:
AT+PWRMANUAL=<manual_mode_enabled>
0 = Disable, 1 = Enable
For more details refer UAPI document section 21.3 Manual Power State Mode.
2. To make power transitions manually:
typedef enum
{
POWER_STATE_NORMAL_OPERATION = 0, POWER_STATE_PARTIAL_SUSPEND,
POWER_STATE_FULL_SUSPENDED, POWER_STATE_FULL_OFF,
POWER_STATE_FACTORY
} power_state;
AT+PWRSTATE=<power_state>, [<delay_minutes>]
NOTE: [<delay_minutes>] valid only when transitioning to Full Off Mode.
For more details refer UAPI document section 21.2 Power State API.
Power Notifications
A variety of power notifications can be enabled including low voltage, Nordic MCU Temperature, transmitter temperature,
battery pack temperature, and power state transitions. These settings and their thresholds can be enabled through the Config
UAPI. For more details refer UAPI document section 21.15 POWER EVENT NOTIFY SETTINGS.
