[SOLVED] RTC alarm script stopped working

Hi

I have the following scripts to wake up the pc and play music in /usr/local/bin

alarmset

#!/bin/bash
#/usr/local/bin

if [ -v 1 ]; then
        echo "" >> /dev/null
else
        echo 'Enter a time for the alarm in the format "MM-DD-YYYY HHMM". See -h for help.'
        exit
fi

if [ $1 == "-h" ]; then
        echo 'Set the alarm for when the computer wakes up from sleep and plays music. Enter "MM-DD-YYYY HHMM" to set the alarm. Time format is 24-hour.'
        echo ''
        echo 'See if an alarm is with "--when".'
        echo 'Reset an alarm with "--reset".'
        exit
fi

if [ $1 == "--when" ]; then
        sudo alarmsetpermission --returnalarmdate
        exit
fi

if [ $1 == "--reset" ]; then
        sudo alarmsetpermission --reset
        echo "No alarm set"
        exit
fi

It has been working flawlessly for waking me up in the morning to my big enjoyment. After a recent update, it has stopped working.

The alarm will work if I set it to a couple of hours in the future, but if I set it to a time i.e. 12 hours in the future, it will not work. The pc will crash and can't manually wake up the machine and have to do a hard reset.

I am not sure, but I don't think that alarmtimer.0.auto was in /sys/class/rtc/rtc0 before:

ls /sys/class/rtc/rtc0
alarmtimer.0.auto  date  dev  device  hctosys  max_user_freq  name  power  since_epoch  subsystem  time  uevent  wakealarm

I don't know how to debug it. Maybe someone knows what the problem is?

Best regards,

Adam

EDIT:

Wrong code in initial post for alarmsetpermission

SOLUTION:

I have grub-customizer installed. I opened grub-customizer, it said that new scripts were detected, pressed save, rebooted and now the pc can sleep for extended periods. Didn't do this when the pc was initially updated.

Re: [SOLVED] RTC alarm script stopped working

The code just echoes the date for the RTC wake up in epoch time to /sys/class/rtc/rtc0/wakealarm.

My last update before my most recent update was 2 - 3 months ago and I changed the bios battery in the meantime. It worked fine after this, also, there is power to the pc at all times. I updated a couple of days ago and around the same time the bios got flashed, but I think it worked normally after this and the RTC is set to managed by OS as default in the bios + RTC wakes up correctly when it is set to a short time frame, so I don't think that it is a hardware problem.

EDIT:

For the music to start playing after the RTC has waken the computer up, the variables must be saved to the disk. So it does this in alarmsetplay, but doesn't use them here:

if [[ $(date '+%s') -gt $(date '+%s' -d "$1/$2/$3 $4:$5") ]]; then

So this should be changed to:

if [[ $(date '+%s') -gt $(date '+%s' -d "$date1/$date2/$date3 $time1:$time2") ]]; then

Doesn't explain why the pc goes into a hardlock when it presumably goes back to sleep when there is no music playing. I will try it now for tomorrow.

EDIT:

The problem is related to a recent update or an error with the bios, and not the script I am using. If the pc goes to sleep for a longer period of time, i.e. >1 hour, it cannot wake up and a hard reset has to be done.

Will probably have to reinstall and reset the bios at some point to get it working.
