Describe the bug
A Bluetooth connect timeout occurs on the RAK4631 immediately when the RAK18001 Buzzer Module (Jiangsu MLT-5020) is plugged in. The issue happens regardless of which slot (A, B, C, or D) the buzzer is connected to.
To Reproduce
- Flash RAK4631 with firmware variant: companion_radio-v1.16.0-59efd86e.
- Plug the RAK18001 Buzzer Module into any slot of the WisBlock Base board.
- Power on the device and attempt to connect via Bluetooth.
- Connection fails with a Bluetooth timeout. (App 1.47.0 Android, also tried with IOS)
Hardware & Software Configuration:
- Board: RAK4631 Core + RAK19007 Base Board (or equivalent)
- Module: RAK18001 Buzzer Module (Jiangsu MLT-5020)
- Firmware Version: RAK_4631_companion_radio-v1.16.0-59efd86e
Additional context
The timeout persists across all available hardware slots, suggesting a potential GPIO/PWM pin assignment conflict in the companion_radio compilation or a power stability issue triggered by the buzzer initialization.
