STM32WB55 BLE Unexpected Event

[ezza23]

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?

Can you give more details about your exact configurations to reproduce this behavior.

Best Regards.

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.
