We are excited to announce the release of BleuIO firmware v2.7.9.11, now available for all users. This update focuses on improving reliability and accuracy by addressing several important bugs identified in previous versions. Whether you are building BLE applications or integrating BleuIO into larger IoT systems, this release ensures a smoother and more dependable development experience.

Key Fixes in v2.7.9.11

Correct BLE Version Reporting
Previously, certain BLE sniffers would incorrectly report the BleuIO dongle as supporting Bluetooth 4.2 instead of Bluetooth 5.0. This bug has now been fixed, ensuring accurate version reporting and alignment with the dongle’s full Bluetooth 5.0 capabilities.

Cleaner Advertising & Scan Response Data
Default advertising and scan response data sometimes contained extra unknown Extended Inquiry Response (EIR) elements. These unnecessary data entries could lead to confusion when testing or deploying. With this fix, developers can now rely on clean and precise advertising packets, making it easier to design reliable BLE applications.

Accurate Preview of Advertising Data
When setting custom advertising or scan response data using AT commands, the preview did not always match the actual values set. This issue has been resolved, giving developers more confidence when configuring advertising parameters for projects such as BLE beacons.

Duplicate Handle Reports Eliminated
In some cases, the AT+NOTI and AT+INDI commands could return duplicate handles. This caused unnecessary repetition and clutter in test logs. With this update, handle reporting is streamlined, making service and characteristic testing more efficient and easier to interpret.

At BleuIO, we continuously refine our firmware to give developers a faster, more stable environment for building and testing Bluetooth Low Energy solutions. Each improvement—no matter how small—saves time in debugging, reduces misinterpretations, and ultimately accelerates your path from prototype to production.

If you are already using BleuIO, we recommend upgrading to the latest firmware to benefit from these bug fixes. For those new to the platform, you can get started by visiting our Getting Started Guide.
