Description
I'm using a RAK 4631 with a RAK 19003 carrier board. I want a super loud buzzer alert for incoming messages. I'm using the unused Tx pin on the RAK 19003, which maps to GPIO 19. In the External Notification module, I have configured the pin using buzzer_gpio, with a nag_timeout of 60 seconds and an output_ms of 1000 ms.
The buzzer sounds but does not stop after 1000 ms. It simply continues to ring until I depress a user button connected to the Rx pin (GPIO pin 20). The buzzer sounds until the nag_timeout is reached. In the past, using a RAK 19007 board, it behaved as expected.
Oscilloscope shows a clean signal. I don't see any serial data or anything weird.
Configuring the device using the buzzer_gpio and enabling use_pwm it seems to work but there is hesitation between ringtones.
