FireflyApi2

1.Overview

FireflyApi2 provides some system interfaces and encapsulates the
functional interface that users need, so that users can use the
system's common interfaces in an easy and simple way. This document is
only a brief description of the interface. For specific use, please
refer to Source code of FireflyApi2Demo.

 page to view and download the latest firmware. At the same time, you
can also synchronize the SDK to the latest submission. The specific
steps are as follows: first, select the corresponding

wiki

, then find the synchronized method in the Android "Development"->
"Build the Android Firmware".

1. Set a scheduled startup

   Function：public void setSchedulePowerOn(int id, boolean enabled, long alarm_time)
   Description：Specify the UTC time, set the scheduled startup, only once without repetition
   Parameters：id  Timed boot ID
   　　　　　　enabled  true(on)/false(off)
   　　　　　　alarm_time  Startup time (UTC time)
   Example：
   //Set start up in one minute, id is 11002
   mFireflyApi2.setSchedulePowerOn(11002,true,System.currentTimeMillis()+60);
   //Cancel operation with ID 11002
   mFireflyApi2.setSchedulePowerOn(11002,false,0);

2. Set a scheduled shutdown

   Function：public void setSchedulePowerOff(int id, boolean enabled, long alarm_time)
   Description：Specify the UTC time, set the scheduled shutdown, only once without repetition
   Parameters：id Scheduled shutdown ID
   　　　　　　enabled true(on)/false(off)
   　　　　　　alarm_time Shutdown time (UTC time)
   Example：
   //Set shutdown after 1 minute, id is 11001
   mFireflyApi2.setPowerOffAlarm(11001, true,System.currentTimeMillis()+60);
   //Cancel operation with ID 11001
   mFireflyApi2.setPowerOffAlarm(11001, false,0);

3. Set a scheduled reboot

   Function：public void setSchedulePowerReboot(int id, boolean enabled, long alarm_time)
   Description：Specify the UTC time, set the scheduled reboot, only once without repetition
   Parameters：id  Scheduled reboot ID
   　　　　　　enabled  true(on)/false(off)
   　　　　　　alarm_time  Reboot time (UTC time)
   Example：
   //Set reboot after 1 minute, id  is 11003
   mFireflyApi2.setSchedulePowerReboot(11003, true,System.currentTimeMillis()+60);
   //Cancel operation with ID 11003
   mFireflyApi2.setSchedulePowerReboot(11003, false,0);

If the above functions do not meet your needs, you can use the
interface to achieve the desired functions through the programming.
This interface is only the most basic scheduled task function, it is
controlled on/off by the incoming ID.

It is invalid after reboot and needs to be manually reset
