If you’re experiencing a hung Raspberry Pi that requires an automatic reboot, you can implement an auto reboot solution to address the issue. By setting up an auto reboot script, you can ensure that your Raspberry Pi restarts itself whenever it encounters a hang or becomes unresponsive.

To configure the auto reboot functionality, you can create a script that periodically checks the system’s responsiveness and triggers a reboot if needed. This script can be scheduled to run at regular intervals using the cron scheduler, which is available in most Linux-based operating systems, including Raspbian.

Here’s a step-by-step guide to help you set up the auto reboot script on your Raspberry Pi:

1. Access your Raspberry Pi either through the terminal or remotely via SSH.
2. Create a new script file using a text editor of your choice. For example, you can use the nano editor with the following command:

Copy codesudo nano autoreboot.sh

3. Inside the script file, add the following lines:

bashCopy code#!/bin/bash
if ! ping -c 1 google.com &> /dev/null; then
  sudo reboot
fi

This script utilizes the ping command to check if the Raspberry Pi can connect to google.com. If the ping fails, indicating a lack of internet connectivity, the script triggers a reboot.

4. Save the script file and exit the text editor.
5. Make the script file executable by running the following command:

bashCopy codesudo chmod +x autoreboot.sh

6. Test the script by manually running it with the following command:

bashCopy codesudo ./autoreboot.sh

If the script detects a lack of internet connectivity, it should initiate a reboot of the Raspberry Pi.

7. Once you have confirmed that the script works correctly, you can schedule it to run automatically using the cron scheduler. Open the cron table for editing:

Copy codesudo crontab -e

8. In the cron table, add the following line to schedule the script to run periodically, such as every 5 minutes:

javascriptCopy code*/5 * * * * /path/to/autoreboot.sh

Make sure to replace /path/to/autoreboot.sh with the actual path to your script file.

9. Save the cron table and exit the text editor.

By following these steps, you will have set up the auto reboot functionality for your Raspberry Pi. The script will periodically check the internet connectivity and automatically reboot the Raspberry Pi if it detects a hang or unresponsive state.

Keep in mind that auto rebooting can be a temporary solution for addressing system hangs, but it’s crucial to investigate the root cause of the issue to ensure long-term stability and reliability.
