We’re excited to announce the latest firmware update for the BleuIO Bluetooth Low Energy USB dongle: Firmware Version 2.7.5. This update introduces valuable new features and optimizations designed to improve usability and functionality. Here’s an in-depth look at what’s new and improved with this release.

Key Features and Improvements in v2.7.5

New Command: ATSAT

With version 2.7.5, BleuIO introduces a new command, ATSAT, which allows users to view the device address type—indicating whether the address is public or private—within scan results. This functionality is particularly useful for users looking to distinguish between public and private address types during Bluetooth scanning. When enabled, ATSAT will display:

• [1] for private addresses
• [0] for public addresses The ATSAT command works seamlessly with the AT+FINDSCANDATA and AT+SCANTARGET commands, which display the address type in scan results. Additionally, AT+GAPSCAN now always shows the device address type, ensuring that users have visibility into the address type for more effective management of scanned devices.

Expanded Bonded Device Capacity

In a significant enhancement to the device’s bonding functionality, this update expands the number of bonded devices that BleuIO can store from 8 to 16. Previously, when the bonding capacity reached the limit of 8 devices, new bonding was not possible until the user manually removed one or all existing bonded devices using the AT+GAPUNPAIR command. With the updated firmware, BleuIO can now store bonding information for up to 16 devices, simplifying the management of Bluetooth connections.

Automatic Removal of Oldest Bonded Devices:

When the 16-device limit is reached, BleuIO will now automatically remove the oldest bonded device that is not currently connected. Given that BleuIO supports a maximum of 8 simultaneous connections, there will always be at least 8 devices in the list that are not actively connected. This new functionality ensures users can always establish a new bond without the need to manually manage bonded devices, thereby improving convenience and user experience.
