We’re happy to announce the release of BleuIO Firmware v2.7.9.70. This update focuses on improving stability and reliability when scanning and connecting to Bluetooth devices.

We recommend all BleuIO users update to the latest firmware to ensure the best performance and the most reliable Bluetooth Low Energy experience.

What’s New in v2.7.9.70

This release includes important bug fixes that improve device behavior during scanning and connection processes.

Fixed Duplicate Scan Results

In previous firmware versions, there were cases where the same Bluetooth device could appear twice in scan results. This could sometimes make it harder to interpret scan outputs or manage discovered devices.

With v2.7.9.70, this issue has been resolved, ensuring scan results are now displayed correctly and consistently.

Improved MTU Exchange Reliability

Another improvement addresses a situation where the MTU exchange was not always triggered after establishing a connection.

MTU exchange is important because it determines the maximum size of data packets transferred between BLE devices. With this fix, the MTU negotiation process is now reliably triggered during connection, improving data transfer stability.
