Pager Nagger

I use my phone as a pager when I'm on-call at work. The Pre's notification tone is way too short and quiet to wake me up. Here's a script that will nag you by playing a .wav file every minute while you have unread messages. The latest version also vibrates and blinks the LEDs.

Prerequisites

• Root access
• Crond enabled

Script code

#!/bin/sh

SOUND=/media/internal/ringtones/pager.wav
LIGHT=1
BUZZ=1

check() {
        cmd='SELECT summary FROM com_palm_messaging_data_ChatThread WHERE unreadCount > 0 AND type = "SMS" AND summary != "";'
        output=$(echo $cmd|sqlite3 /var/luna/data/dbdata/PalmDatabase.db3 2> /dev/null) || return 0
        if [ -n "$output" ] ; then
                return 1
        fi
}

play() {
        x=0
        until [ "$x" = 4 ] ; do
                aplay -q "$SOUND" &
                y=1
		if [ "$BUZZ" = 1 ] ; then
			/usr/bin/luna-send -n 1 palm://com.palm.vibrate/vibrate {\"period\":1,\"duration\":1000\} > /dev/null 2>&1
			z=10

	                sleep 60
               		check
                	if [ "$?" = 1 ] ; then
                        	x=$((x + 1))

        done

if [ ! -f "$SOUND" ] ; then
        SOUND=/usr/palm/sounds/alert.wav

check || play

Installation

1. Copy a .wav file to /media/internal/ringtones/pager.wav (or to the ringtones directory in USB mode).

mkdir -p /opt/scripts

1. Copy the script to /opt/scripts/pager.

chmod +x /opt/scripts/pager
rootfs_open -w

1. Add the following line to /etc/cron/crontabs/root:

*/5 * * * * /opt/scripts/pager

Remember to copy a .wav file to /media/internal/ringtones/pager.wav.

To Do/Bugs

As the message is marked read in the database when it is closed, the sound will continue to play every minute until the messaging app is closed (or until that chat card is closed if you've done the Create a new card for each conversation mod).
