The latest firmware update for BleuIO, version 2.7.3, brings a suite of new functionalities and commands designed to enhance the performance and user experience of this Bluetooth Low Energy (BLE) USB dongle. With continuous firmware updates, BleuIO ensures that users can develop BLE applications quickly and efficiently. Here’s a detailed look at what the new update offers:

New Functionalities in v2.7.3

1. Bonded Device Connectivity Improvement:
   • A new command has been introduced to scan for and connect to bonded devices, even if these devices are using a Private Random Resolvable Address. This improvement ensures that devices can maintain secure connections and improve overall reliability in various use cases.
2. Toggle Resolved Addresses in Scan Results:
   • Users now have the option to toggle on or off the display of resolved addresses in scan results. This feature can be activated when using the AT+GAPSCAN command, providing greater control over the information displayed during device scans.
3. Index-based Connection Command:
   • The AT+GAPCONNECT command has been enhanced to allow the use of an index from scan results obtained via the AT+GAPSCAN command. This simplifies the connection process by removing the need to input the full MAC address.
4. Verbose Mode Index Display:
   • A new command allows users to toggle on or off the display of indexes from AT+GAPSCAN scan results in verbose mode. This feature is particularly useful for developers who need detailed scan information for debugging and development purposes.

New Commands Added

1. AT+CONNECTBOND:
   • This command facilitates connection with already bonded devices, even if these devices are advertising using a Private Random Resolvable Address. It streamlines the reconnection process and enhances device management.
2. ATSRA:
   • This command enables the display of resolved addresses in the scan results. It is a useful tool for users who need to view detailed addressing information during device scans.
3. ATSIV:
   • This command allows users to show indexes in the verbose mode scan results. It provides an additional layer of information that can be crucial for in-depth analysis and debugging.

The v2.7.3 firmware update for BleuIO brings significant enhancements that improve both connectivity and usability. By adding new commands and functionalities, BleuIO continues to support developers in creating robust and efficient BLE applications. Whether you’re working on a new project or maintaining an existing application, these updates offer valuable tools and improvements to streamline your development process.
