The BleuIO Bluetooth Low Energy (BLE) USB dongle continues to set the standard for BLE application development with its latest firmware update, version 2.7.2. This update brings significant enhancements, focusing on security features and critical bug fixes, making it an essential upgrade for developers and users of BleuIO.

Key Enhancements in Firmware 2.7.2

Enhanced Security with Authentication and Encryption Permissions

One of the most notable additions in this update is the introduction of Authentication and Encryption Permission support for Custom Service attributes. This feature is a major step forward in ensuring secure BLE communications. The permissions framework allows the server (BleuIO) to determine the client’s access level to characteristic or descriptor values based on the need for an authenticated and/or encrypted connection. This means that sensitive data can now be protected more robustly, ensuring that only authorized clients can read from or write to specific attributes.

Bug Fixes and Stability Improvements

The 2.7.2 firmware update also addresses several bugs that were affecting the reliability and performance of the BleuIO dongle. Here are the key fixes:

1. AT+GETBOND Command Bug Fixes:
   • Incorrect MAC Addresses: Previously, the AT+GETBOND command occasionally returned incorrect MAC addresses. This issue has now been resolved, ensuring accurate reporting of bonded device addresses.
   • Removal of Address Type: The address type part of the MAC address, which was always returned as PUBLIC_ADDRESS (0) and not stored with the bonding information, has been removed. This simplification helps in reducing confusion and potential errors in handling bonded device information.
2. AT+GAPSCAN Command Stability:
   • The command AT+GAPSCAN= with an empty argument previously caused the device to reset unexpectedly. This bug has been fixed, ensuring stable and predictable behavior when scanning for devices.
3. Connection Initiation Fixes:
   • The update resolves issues where attempting to initiate a connection using AT+GAPCONNECT while also advertising led to unpredictable behavior, such as being unable to connect or scan properly. This fix enhances the overall stability and reliability of establishing BLE connections.

For developers and users of the BleuIO dongle, updating to firmware version 2.7.2 is highly recommended. The new security features ensure that your BLE applications can enforce stringent access controls, protecting sensitive data. The bug fixes improve the overall functionality and reliability of the device, reducing the likelihood of encountering errors during development and deployment.

BleuIO, has recently unveiled its latest offering: Python Library v1.3.1. This release brings a range of improvements and features, including support for the SUOTA (Software Updates Over The Air) commands introduced in BleuIO firmware version 2.4.0. Additionally, it addresses a bug that affected MacOS users, making the library more robust and user-friendly.

Support for SUOTA Commands:

One of the standout features of BleuIO’s Python Library v1.3.1 is its support for SUOTA commands. SUOTA, which stands for Software Updates Over The Air, is a critical feature for any BLE device. It allows users to update firmware wirelessly, eliminating the need for physical connections or manual updates. With this library update, developers working with BleuIO now have a powerful tool at their disposal to streamline firmware updates for their BLE devices. Whether it’s fixing bugs or adding new features, the ability to update firmware over the air provides flexibility and convenience, ultimately enhancing the user experience.

Bug Fix for MacOS Users:

The new Python library also includes a significant bug fix for MacOS users. Previously, there was an issue where serial responses were sometimes returned in two parts instead of one when using the library on MacOS. This inconsistency could lead to compatibility problems and hinder the development process. BleuIO has promptly addressed this issue, ensuring that the library can now handle serial responses that come in multiple parts. This improvement guarantees a smoother experience for MacOS users and eliminates a common frustration during development.

The Python Library v1.3.1 by BleuIO is readily available for developers on the Python Package Index (PyPI). You can access and download the library from the following link: BleuIO Python Library on PyPI. This convenient accessibility ensures that developers can easily integrate the library into their projects and start benefiting from the new features and bug fixes immediately.

BlueIO, a prominent player in the Bluetooth industry, has recently unveiled its firmware version v2.3.1. This update comes packed with exciting additions and crucial bug fixes, promising a more seamless and efficient Bluetooth experience.

Enhanced Features:

AT+SCANFILTER Upgrade: One of the standout features of the v2.3.1 firmware update is the enhancement made to the AT+SCANFILTER functionality. Previously, this feature only filtered based on UUID, but now, it has been extended to include “Service Data – 128-bit UUID” and “Service Data – 16-bit UUID” packets. This means that when filtering devices, you can now fine-tune your criteria even further, ensuring that only the most relevant devices are detected. This added flexibility is a significant boon for developers and users alike, enabling a more tailored Bluetooth experience.

Critical Bug Fixes:

SPS Message Recognition: Before the v2.3.1 update, some users may have encountered a frustrating issue where the dongle failed to recognize SPS (Serial Port Service) messages correctly. This problem stemmed from the system incorrectly handling messages due to a different handle, resulting in an improper display format that did not align with previous firmware versions. However, with the diligent efforts of the BlueIO team, this bug has been decisively squashed. Now, SPS messages are correctly recognized and displayed in a consistent manner, eliminating the confusion and inconvenience experienced by users.

AT+GETCONN Bonded Device Display: Another critical bug addressed in this firmware update relates to the AT+GETCONN command. Previously, when users attempted to reconnect with previously bonded or paired devices, these devices would not show up as bonded or paired during the reconnection process. This inconsistency could lead to unnecessary complications and frustration for users. Thankfully, BlueIO has rectified this issue in v2.3.1. Now, when you reconnect with your trusted devices, they will correctly appear as bonded or paired, streamlining the reconnection process and ensuring a smoother user experience.

Be sure to update your BlueIO firmware to v2.3.1 to take full advantage of these improvements and enjoy a more hassle-free Bluetooth experience.
