问题 I am writing a sleepy driver. Here any process that tries to write to the device file should sleep for 'n' number of seconds supplied by the user. Reader process should wake up all the waiting processes. Writer code : printk("Invoking interruptible_timeout for device flag[%d] = %d\n", idn, flag[idn]); long ret = wait_event_interruptible_timeout(wq[idn],flag[idn]==1,sec*HZ)/HZ; //flag[idn]=0; printk("timeout returned : %d idn = %d\n", ret, idn) printk("writer : flag[%d] = %d\n", idn, flag[idn]

问题 Can iOS receive iBeacon packet in sleep state and wake up the app? I killed an app and restarted, then kept the phone in sleep mode. The device was was in beacon region when device reboot and I kept the device screen off after reboot. My iOS app is not waking, so I suspect its not receiving iBeacon packet. I checked the system log and found that the didEnterRegion procedure is not getting called. Does app wakeup works incase of force terminated app and does iOS receive iBeacon packet in

问题 I am trying to wakeup my android app via nearby bluetooth devices. If I force close the app (in Android 8.0 and above), and when I bring my Android device near to a BLE device, can I get a callback or intent callback so that I can push a ForeGround service and make the app stay awake. I tried scanning for the BLE devices nearby but when the app is force killed, the BLE scan stops and I cannot wake up the app via BLE nearby devices. 回答1: Force stop kills application totally. It won't get FCMs,

Programmatically wake display on OSX

问题 I've managed to get the display to sleep immediately with pmset displaysleepnow in terminal, however for waking the display I've only found pmset schedule wake "12/24/2009 00:00:00" which fails to work if I try to schedule anything earlier than at least 10secs from now. Is there any way to programmatically wake the display in Cocoa? Someone has suggested IOPMAssertionDeclareUserActivity but I couldn't find any examples on this so I am struggling. I am using Swift by the way, but Objective C

问题 I need to allow WakeTimers (computer wake up from sleep/hibernation) for all power plans set on plugged in to Enabled. I tried Win32_PowerSetting but it only works on english version of Windows. I need to use .NET 2.0 Thanks for responses ! 回答1: I suspect you can do this using API calls to powrprof.dll, as well as WMI, but I haven't had the time to figure that approach out. This setting appears to be simply a boolean registry key that is located according to your current power plan: HKEY

how to wakeup android phone from sleep?

How to wakeup android phone from sleep (suspend to mem) programmably? I don't want to acquire any wakelock, which means the phone goes into "real" sleep with the cpu disabled. I guess I can use some kind of RTC (real time clock) mechanism? Does anyone have any examples? Thanks. In order to let the Activity wake up the device and not require a password/swipe, you only need to add a few flags. To get that, include to your code: this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
