Pager Nagger

WARNING! DANGER!

This script is known to cause the wiping of data on webOS devices and may leave you with a non-functional device that may require the use of webOS Doctor to fully recover from. In short, sqlite is designed for one user per database. Accessing PalmDatabase.db3 in sqlite3 while Luna is running will eventually create a conflict where both Luna and this script attempt to access this database at the same time. When this happens, Luna will assume that its database is corrupt, delete it, recreate it, reset the "first use" status flag, and reboot.

Members of the community are currently investigating a better solution that works using the standard webOS application / service architecture. In the mean time, this script is considered to be dangerous.

You have been warned.

Re: warning

I'm not entirely convinced the crash related to the nagger. My nagger is/was a daemon written in C that did pretty much the exact same thing as the shellscript (but also checked the email address of the 6245 SMS). I have attached a crashlog to this page.

Original Document HEAD

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

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).

Acknowledgments

Thanks to Sargun for the tracking script which inspired the layout of the code, as well as started me looking at the databases.

This is great thanks!!
