Version 0.9.3 is a maintenance and integration release focused on simplifying buzzer support by moving audio playback to the standalone WLED Buzzer Usermod.
Highlights
- Removed the internal iDotMatrix buzzer backend.
- Added optional integration with the external WLED Buzzer Usermod.
- Removed iDotMatrix-specific buzzer GPIO, Active/Passive type, polarity, LEDC and timing configuration.
- Added a single Buzzer → Enable option to the iDotMatrix settings.
- The option is available when the external Buzzer Usermod is installed.
- Without the Buzzer Usermod, iDotMatrix continues to compile and run normally with buzzer support disabled.
- Added external buzzer feedback for:
- BLE connection
- BLE disconnection
- Countdown completion
- Alarm
- Program / Schedule
- Silent Alarm and Program / Schedule configurations remain silent when requested by the protocol.
External Buzzer integration
Buzzer support now requires the standalone WLED Buzzer Usermod.
The integration is optional and does not create a hard build dependency:
- Buzzer Usermod installed: buzzer integration is available.
- Buzzer Usermod not installed: iDotMatrix works normally and the Buzzer option remains disabled.
