We are pleased to announce the release of firmware v2.7.9.51 for the BleuIO SSD005. This update focuses heavily on improving overall stability and strengthening the firmware’s ability to handle complex Bluetooth Low Energy operations. The result is a smoother, more reliable experience for developers and users working with demanding BLE environments.

Stability Improvements

This version delivers significant enhancements to the firmware’s internal handling of data-intensive operations. As BLE devices continue to grow in complexity, the dongle must process larger amounts of information quickly and without interruption. The new update refines these processes, reducing the risk of unexpected behavior and ensuring that the dongle performs more consistently during everyday use.

Improved Handling of Large Service and Characteristic Discoveries

A key focus of this release was resolving an issue that could cause the dongle to reboot when discovering a large number of services and characteristics. Devices with extensive GATT profiles place additional strain on the system, and the previous firmware could occasionally become overwhelmed. Version 2.7.9.51 addresses this problem by improving how these discoveries are managed, resulting in a far more reliable interaction with complex peripherals.

Strengthened Internal Checks for Scan Results and Notifications

The update also refines several internal validation mechanisms. Earlier versions, under specific conditions, could trigger a sudden reboot while viewing scan results or handling incoming notifications. These checks have now been reinforced, allowing the dongle to operate more securely even when managing rapid or high-volume BLE traffic.

Fixes for Write Operations and Notification Configuration

Two commonly used AT commands received important stability fixes in this release. The AT+GATTCWRITEWRB command, used for write operations, previously encountered rare cases where insufficient validation could lead to an unexpected reboot. Similarly, the command for setting notifications, AT+SETNOTI, has been improved to ensure stable behavior when enabling or adjusting notification settings. These corrections help ensure dependable communication between the dongle and connected devices, particularly in applications that rely heavily on write requests and real-time notifications.

A More Resilient Platform for Developers

Firmware v2.7.9.51 marks another meaningful step toward making the SSD005 dongle a highly dependable tool for BLE development. By addressing edge-case stability issues and strengthening how the dongle handles large or rapidly changing data sets, this update offers a more resilient foundation for both prototyping and production-level applications.

How to Update

The new firmware is available for download on the BleuIO support website. We encourage all users to upgrade to this version to take advantage of the improved stability and robustness it provides.
