Subject: Support Required – BLE_Audio_PBP_Sink Auracast Receiver Not Visible on Mobile
Hi Team,
I am currently working on the Auracast project using the STM32WBA55G-DK1 board.
In this setup, the board is configured as the receiver side (Sink). After building and flashing, the board is expected to appear as AURACAST SINK STM32Auracast1, 2, 3, etc.
The project code location I am using is:
/home/engineer/Music/STM32CubeWBA/Projects/STM32WBA55G-DK1/Applications/BLE/BLE_Audio_PBP_Sink
I have also tested with the following smartphones that support BLE Audio / Auracast: but not able to see device information related to receiver side device in phone
Google Pixel: Pixel 7 / 7 Pro, Pixel 8 / 8 Pro, Pixel 9 / 9 Pro / 9 Pro XL / 9 Pro Fold
OnePlus: OnePlus 11, 12, 13
Issue Observed
After building and flashing the board, I am not able to see or connect to the advertising device from the mobile phone.
Verified with different Android versions and Bluetooth versions.
Enabled BLE Audio Auracast configuration in phone settings.
Despite this, the board does not appear in scanning.

Request
Could you please help confirm:
If any code modifications are required to enable advertising/discovery?
Whether any configuration changes are needed on the STM32WBA55G board for Auracast Sink visibility?
If there are additional flags or features that need to be enabled in the project configuration?
Your guidance on resolving this issue will be very helpful.
Thanks & Regards,
Jeevan MV
