Overview

Power Manager monitors Power IR key events and reacts to power state changes.
It dispatches Power Mode Change events to IARM-Bus.
All listeners should release resources when entering POWER OFF/STANDBY state and re-acquire them when entering POWER ON state.
Power manager sends these events to other applications
IARM_BUS_PWRMGR_EVENT_MODECHANGED
IARM_BUS_PWRMGR_EVENT_DEEPSLEEP_TIMEOUT
The Event Data contains
current power state - IARM_Bus_PWRMgr_PowerState_t curState;
new power state and - IARM_Bus_PWRMgr_PowerState_t newState;
Timeout - unsigned int timeout;
Power manager publishes four RPC Methods:
SetPowerState
GetPowerState
WareHouseReset
SetDeepSleepTimeOut

Events

IARM_BUS_PWRMGR_EVENT_DEEPSLEEP_TIMEOUT

Event to notify deep sleep timeout
Deep sleep timeout is set by “IARM_BUS_PWRMGR_API_SetDeepSleepTimeOut” API after which this event will be broadcast.

IARM_BUS_PWRMgr_DeepSleepTimeout_EventData_t param;
param.timeout = deep_sleep_delay_in_seconds;
IARM_Bus_BroadcastEvent( IARM_BUS_PWRMGR_NAME,
IARM_BUS_PWRMGR_EVENT_DEEPSLEEP_TIMEOUT,
(void*)&param, sizeof(param));

IARM_BUS_PWRMGR_EVENT_MODECHANGED

Event to notify power mode change.
This event is broadcast in case of power state change. Along with the current power state and new state, this event is broadcast. This event can be handled by the application.

IARM_Bus_PWRMgr_EventData_t param;
param.data.state.curState = curState;
param.data.state.newState = newState;
IARM_Bus_BroadcastEvent( IARM_BUS_PWRMGR_NAME,
IARM_BUS_PWRMGR_EVENT_MODECHANGED,
(void *)&param, sizeof(param));

RPC Methods

IARM_BUS_PWRMGR_API_SetPowerState

Sets the power state of the device
Used to set a new power state to the device.
The power state can be ON, OFF, STANDBY, STANDBYLIGHT-SLEEP or STANDBY-DEEP-SLEEP

IARM_Bus_PWRMgr_SetPowerState_Param_t param;
param.newState = IARM_BUS_PWRMGR_POWERSTATE_ON
IARM_Bus_Call(IARM_BUS_PWRMGR_NAME,
IARM_BUS_PWRMGR_API_SetPowerState,
(void *)&param, sizeof(param));

IARM_BUS_PWRMGR_API_GetPowerState

This API is used to retrieve the current power state of the box.

IARM_Bus_PWRMgr_GetPowerState_Param_t param;
IARM_Bus_Call(IARM_BUS_PWRMGR_NAME,
IARM_BUS_PWRMGR_API_GetPowerState,
(void *)&param, sizeof(param));

IARM_BUS_PWRMGR_API_WareHouseReset

This API is used to reset the box to warehouse state.

IARM_Bus_Call(IARM_BUS_PWRMGR_NAME,
IARM_BUS_PWRMGR_API_WareHouseReset, NULL, 0);

IARM_BUS_PWRMGR_API_SetDeepSleepTimeOut

This API is used to sets the timeout for deep sleep

IARM_Bus_PWRMgr_SetDeepSleepTimeOut_Param_t param;
param.timeout = timeOut;
IARM_Bus_Call(IARM_BUS_PWRMGR_NAME,
IARM_BUS_PWRMGR_API_SetDeepSleepTimeOut,
(void *)&param, sizeof(param));
