STM32WB55 BLE Unexpected Event

ezza23 · ‎2024-07-04

I got the STM32W55 MCU.

We keep receiving an event from the stack:

Event type: 0xff -->

HCI_VENDOR_SPECIFIC_DEBUG_EVT_CODE

Event e-code: 0x04

/* ACI_HAL_END_OF_RADIO_ACTIVITY_EVENT code */
#define ACI_HAL_END_OF_RADIO_ACTIVITY_VSEVT_CODE          0x0004U

We receive it in an infinite loop.

Can you please advice?

Hello @ezza23

Hi Ezza,

This event is triggered because most probably in your code you registered to receive radio_activity_event ( By default it is the case in ST code example)

To register to radio activity event, I suppose you have a call to aci_hal_set_radio_activity_mask()

This command allow to define radio activity report you want to receive.

If you don't want to receive such report ( ACI_HAL_END_OF_RADIO_ACTIVITY_VSEVT_CODE). You simply need to remove call to aci_hal_set_radio_activity_mask().

Best Regards.
