Bluetooth LE Audio Revolutionizes Wireless Audio
Colin Ramrattan - Salvo Bonina - STMicroelectronics - Watch Now - Duration: 34:26
Explore Bluetooth® LE Audio with Auracast™ & STMicroelectronics’ STM32WBA MCU solution. Auracast™ enables audio broadcast capabilities to Bluetooth LE devices and opens new use cases such as shared audio experiences and assistive listening.
The AN5928 is already published at st.com:

Thank you
What distance can be achieved with BLE ?
Hi Davek,
in an open field in line-of-sight using the 1Mbit PHY you can achieve a few hundreds of meters, while using the long-range mode you can even go over a kilometer.
What are the difference in memory usage (RAM and FLASH) between the full and the basic BLE stack ?
Hello Nathan,
Regarding the ram and flash usage, there is an update coming to :
AN5928 which is your reference document for both stacks.
Today we have the following as a guideline but subject to change as fixes and improvements are implemented:
Basicstack_Beacon application: Flash: 116Kbyte, SRAM 14.3Kbyte
Fullstack_Beacon P2P Server application: Flash: 226Kbyte, SRAM 24.1Kbyte
What is the typical audio latency?
In LE Audio the latency is <30ms
very nice
When is AN5928 expected to be released?
