We are happy to announce the release of BleuIO firmware v2.7.9.6.
This update brings an important new feature designed to make your device more secure: password protection for the AUTOEXEC list.

With this functionality, you can lock your AUTOEXEC list using a password. Once locked, no one can read, modify, or delete the commands inside unless they enter the correct password. The password will remain active even after power cycles, ensuring your setup stays protected. Please note that updating the firmware to a different version will clear the password.

What’s New in v2.7.9.6

Added Functionality

• Ability to lock the AUTOEXEC list with a password.
• Password protection persists through power cycles.
• Updating firmware to another version will clear the password.

New Commands

We’ve introduced three new AT commands to manage this feature:

1. AT+SETAUTOEXECPWD
   • Create or change a password for the AUTOEXEC list.Requires the old password if you want to change it.Maximum length: 255 ASCII characters.
   Example: AT+SETAUTOEXECPWD=my_password
2. AT+ENTERAUTOEXECPWD
   • Used to enter the password when prompted.Grants access to locked commands.
3. AT+CLRAUTOEXECPWD
   • Clears the existing password (requires entering the password first).Returns the AUTOEXEC list to an unprotected state.

How to Use the New Feature

The recommended way to use this functionality is:

1. Add commands to your AUTOEXEC list as usual.
2. Lock the list by setting a password with AT+SETAUTOEXECPWD.
3. If you need to make changes later:
   • Use AT+CLRAUTOEXECPWD to remove the password.
   • Modify your AUTOEXEC list.
   • Lock it again using AT+SETAUTOEXECPWD.

When a password is set, the following commands will require authentication first:

• AT+CLRAUTOEXECPWD
• AT+SETAUTOEXECPWD
• AT+AUTOEXEC
• AT+AUTOEXECLOOP
• AT+CLRAUTOEXEC

Why This Matters

The AUTOEXEC list is a powerful tool that allows you to automate commands when your BleuIO dongle starts up. By adding password protection, you ensure that only authorized users can view or change these startup configurations. This is especially important in production environments where security and stability are critical.
