Category: BleuIO firmware updates

We’re excited to announce the release of BleuIO Pro Firmware v1.0.4.14, bringing enhanced control, improved security, and extended functionality to your Bluetooth development experience. This update focuses on giving users more flexibility in automation while keeping sensitive configurations protected.

New: Password Protection for AUTOEXEC List

One of the most significant updates in this release is the ability to lock the AUTOEXEC list with a password.

The AUTOEXEC list allows you to automate commands that run when the device powers on. In previous versions, anyone with access to the device could read, modify, or delete these commands.

With the new password feature, you can now secure your automation scripts by setting a password that prevents unauthorized access or changes.

• Once a password is set, the list is locked — meaning it cannot be viewed or modified without entering the correct password.
• The password persists through power cycles, ensuring protection even after the device restarts.
• Updating the firmware to a different version will clear the password, allowing you to reset it if needed.

This feature is especially useful for developers deploying BleuIO Pro in environments where multiple users might interact with the device, ensuring that sensitive setup scripts remain intact.

Extended Wait Time for AT+WAIT Command

Another improvement is the extended maximum wait time for the AT+WAIT command.
Previously limited to 60 seconds, the command can now wait up to 1 hour (3600 seconds) — matching the functionality of the BleuIO (SSD005).

This enhancement provides more flexibility for time-sensitive applications or scenarios that require extended delays between command executions, such as long data collection intervals or connection monitoring.

New Commands Added

To support the new password-protection functionality, several new AT commands have been introduced:

1. AT+SETAUTOEXECPWD

Used to create or set a password for the AUTOEXEC list.
If a password already exists, you’ll need to provide the old one before setting a new one.

2. AT+ENTERAUTOEXECPWD

Allows you to enter the password when prompted to access or modify the AUTOEXEC list.

3. AT+CLRAUTOEXECPWD

Used to clear or remove an existing password.
To do so, the correct password must be entered first — adding an extra layer of protection.

These commands make it easy to manage your device’s security without complicating the user experience.

Bug Fixes and Improvements

• Fixed an issue in verbose mode where some error codes and error messages did not match.
  This update ensures more accurate debugging information and smoother development workflows.

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.

BleuIO, a leading Bluetooth Low Energy (BLE) USB dongle, continues to evolve with its latest firmware updates —version 2.7.8 for BleuIO and version 1.0.3 for BleuIO Pro. This new release builds upon the Auto Execution feature introduced in our previous firmware release by adding a powerful Auto Execution Loop, allowing users to automate repetitive tasks seamlessly. With this enhancement, developers can set up loops in the AUTOEXEC list, enabling continuous execution of commands without manual intervention.

What is Auto Execution Loop?

The Auto Execution feature allows users to store and run AT commands automatically upon startup, making BLE development faster and more efficient. With the new Auto Execution Loop, you can now create loops within the AUTOEXEC list, All auto-execute commands between the loop start and loop end will continue running indefinitely until manually stopped by clearing the auto-execute list using AT+CLRAUTOEXEC.

This feature is particularly useful for scenarios where continuous execution of BLE tasks is required, such as:

• Beacon advertising with dynamic data updates
• Changing BLE characteristics periodically
• Automated device-to-device communication
• Repeating sensor data transmission

How to Use the Auto Execution Loop

Setting up a loop in the AUTOEXEC list is simple and requires only a few steps:

1. (Optional) Add any commands that should run once before the loop starts using AT+AUTOEXEC=*command*.
2. Define the start of the loop using AT+AUTOEXECLOOP=START.
3. Add the commands that should execute repeatedly with AT+AUTOEXEC=*command*.
4. Mark the end of the loop using AT+AUTOEXECLOOP=END.
5. Restart the BleuIO dongle to see the commands execute automatically on startup. Alternatively, plug it into any power source, like a power bank or USB adapter, and let it run autonomously.

To clear the AUTOEXEC list and stop an ongoing loop, simply use AT+CLRAUTOEXEC. This ensures that any active command sequence is halted.

Real-World Use Cases

1. Dynamic BLE Beacon

Start-up: Disables scan response message and starts advertising.

In loop: Sets the advertising name in advertising data to ‘BleuIO’, waits 10 seconds, sets advertising name to ‘CAT’, waits 10 seconds.

Test: Scan the dongle to see the name change every 10 seconds.

Commands:

AT+AUTOEXEC=AT+ADVRESP=00
AT+AUTOEXEC=AT+ADVSTART
AT+AUTOEXECLOOP=START
AT+AUTOEXEC=AT+ADVDATA=04:09:42:6C:65:75:49:4F  // Name: BleuIO
AT+AUTOEXEC=AT+WAIT=10
AT+AUTOEXEC=AT+ADVDATA=04:09:43:41:54  // Name: CAT
AT+AUTOEXEC=AT+WAIT=10
AT+AUTOEXECLOOP=END

2. BLE Peripheral with Notify Characteristic

Start-up: Creates a custom service with a characteristic with the notify property. Starts advertising.

In loop: Changes the characteristic value to ‘First Value’, waits 10 seconds, changes the value to ‘Second Value’, waits 10 seconds.

Test: Connect to the dongle and subscribe to the notification characteristic to see it toggle between the two values every 10 seconds.

Commands:

AT+AUTOEXEC=AT+CUSTOMSERVICE=0=UUID=72013640-2f23-49bb-8edd-6636969a2545
AT+AUTOEXEC=AT+CUSTOMSERVICE=1=UUID=72013641-2f23-49bb-8edd-6636969a2545
AT+AUTOEXEC=AT+CUSTOMSERVICE=1=PROP=RWN
AT+AUTOEXEC=AT+CUSTOMSERVICE=1=PERM=RW
AT+AUTOEXEC=AT+CUSTOMSERVICE=1=LEN=20
AT+AUTOEXEC=AT+CUSTOMSERVICE=1=VALUE=Value
AT+AUTOEXEC=AT+CUSTOMSERVICESTART
AT+AUTOEXEC=AT+ADVSTART
AT+AUTOEXECLOOP=START
AT+AUTOEXEC=AT+CUSTOMSERVICE=1=VALUE=First Value
AT+AUTOEXEC=AT+WAIT=10
AT+AUTOEXEC=AT+CUSTOMSERVICE=1=VALUE=Second Value
AT+AUTOEXEC=AT+WAIT=10
AT+AUTOEXECLOOP=END

3. Device-to-Device Communication

Start-up: Enables verbose mode.

In loop: Connects to another dongle, waits 10 seconds to ensure connection, sends an SPS message ‘HELLO’, waits 10 seconds before disconnecting, then waits 60 seconds.

Test: Set up a second dongle to advertise and run AT+GETMAC on it to obtain the MAC address. Use that address in the first dongle’s AUTOEXEC list when adding the AT+GAPCONNECT command. Monitor the terminal on the second dongle to see the first dongle connecting and sending ‘HELLO’ every minute.

Commands:

AT+AUTOEXEC=ATV1
AT+AUTOEXECLOOP=START
AT+AUTOEXEC=AT+GAPCONNECT=[0]*MAC_ADDRESS*
AT+AUTOEXEC=AT+WAIT=10
AT+AUTOEXEC=AT+SPSSEND=HELLO
AT+AUTOEXEC=AT+WAIT=10
AT+AUTOEXEC=AT+GAPDISCONNECT
AT+AUTOEXEC=AT+WAIT=60
