Hello @rs-dp
The encrypted advertising require the use of the ACI_HAL_EAD_ENCRYPT_DECRYP command for encryption and decryption. And according to the AN5270 HAL command table, this command is supported only using the stm32wb5x_BLE_Stack_full_extended_fw. That’s why we can’t use the stm32wb5x_BLE_Stack_full_fw.
Best Regards.
