BLE general description
The BLE block is a master/slave processor, compliant with Bluetooth specification 5.2
standard.
It integrates a 2.4 GHz RF transceiver and a powerful Cortex®-M0+ core, on which a
complete power-optimized stack for Bluetooth Low Energy protocol runs, providing
master / slave role support
GAP: central, peripheral, observer or broadcaster roles
ATT/GATT: client and server
SM: privacy, authentication and authorization
L2CAP
Link layer: AES-128 encryption and decryption
MSv63013V2
Note: UFQFPN48: VSS through exposed pad, and VSSRF pin must be connected to ground plane
