It's the Bluetooth HCI protocol. You can download the manual at https://www.bluetooth.com/specifications/adopted-specifications. Press "Core Version 5.0" to download the current version (5). If you check out Vol 2 Part E chapter 7, you will see all kind of packets. The ACL data packets depend on what kind of data it is (higher layer specification). For example GATT, you will find the documentation in Vol 3 Part G.
