Flipper Zero Firmware Release 0.93

Flipper Zero is a multi-tool designed for penetration testers and tech enthusiasts. It resembles a toy but packs powerful features for hacking various digital devices and systems. These include exploring radio protocols, bypassing access controls, and interacting with hardware. 

Flipper Zero is open-source, allowing for customization and extension according to your needs.

This information introduces Flipper Zero Firmware Release 0.93, a recent update for Flipper Zero. There’s likely more to discover about this release’s specific features and improvements.

Flipper Zero Firmware Release 0.93 – Core Functionality – BLE (Bluetooth Low Energy)

Flipper Zero Firmware release 0.93 brings improvements to BLE functionality:

• Upgrade to radio stack release 1.17.3: This upgrade likely improves BLE communication’s overall stability and performance.
• Improved compatibility with older iOS versions for BLE HID means Flipper Zero’s BLE HID (Human Interface Device) functionality should work better with older iPhones and iPads.

I couldn’t find details on the specific improvements in radio stack release 1.17.3, but you can check the Flipper Zero release notes for more information.

Flipper Zero Firmware Release 0.93 – New Features and Improvements

Notifications

• Enhanced handling of always-on backlight override: This suggests better control over the backlight behavior when notifications are displayed. Previously, the backlight might have stayed on continuously even if you had set it to turn off after a period of inactivity.
• With this improvement, notifications likely no longer prevent the backlight from turning off as intended.

GUI (Graphical User Interface)

• Improvements to HEX keyboard UI: The update likely introduces refinements to how hexadecimal data is displayed and interacted with on Flipper Zero’s user interface. This could involve easier input, editing, or visualization of hexadecimal values.

For specific details on the GUI and notification changes, it’s best to refer to the official Flipper Zero release notes:

These notes might mention the exact UI improvements or how the backlight handling for notifications has been changed.

FuriHal (Hardware Abstraction Layer)

• Various CCID (Chip Card Interface Device) enhancements: This indicates improvements related to how Flipper Zero interacts with chip cards. CCID is a standard that allows devices to communicate with smart cards and similar devices. The update might improve compatibility with a wider range of chip cards or enhance their functionality when used with the Flipper Zero Firmware.

Unfortunately, the available information doesn’t provide specific details on these CCID enhancements. You can check the Flipper Zero documentation or forums for more information on how these changes might impact your use of chip cards with the Flipper Zero.

Documentation

• Guide for Sub-GHz bin raw file format: This is a documented addition in Firmware 0.93. The Sub-GHz functionality of the Flipper Zero deals with low-frequency radio signals used in various devices like key fobs, garage door openers, and some RFID systems. The new guide likely explains creating and using “.sub” files containing raw signal data for these Sub-GHz protocols.

This documentation should be helpful for advanced users who want to explore sending and receiving custom radio signals unsupported by Flipper Zero’s built-in protocols.

Other Areas (based on available information)

• System improvements: The update likely includes bug fixes and general performance enhancements for Flipper Zero’s core system.
• Build system improvements are likely behind-the-scenes changes that improve the building and deployment of new firmware versions for Flipper Zero.

Unfortunately, without more details, it’s difficult to specify the exact changes in these areas. You can check the Flipper Zero Firmware community forums or changelogs for discussions or mentions of these improvements.

Conclusion

Flipper Zero Firmware release 0.93 brings various improvements across different functionalities. Notably, the update enhances BLE compatibility with older iOS devices and offers better control over backlight behavior during notifications.

The update also includes improvements to the user interface for hexadecimal data handling and introduces documentation for the Sub-GHz bin raw file format.

While some areas, like system and build system improvements, lack specifics, this firmware update seems to solidify Flipper Zero’s capabilities for pen testers and tech enthusiasts.
