Bluetooth Low Energy Service

Silfi Bluetooth is divided into two parts: one is the Bluetooth LE (BLE) service, which provides standard Bluetooth LE APIs and enhanced services for user development; the other is a fully tested BLE 5.2 protocol stack with host and controller components.

The BLE service runs on HCPU or LCPU. It provides standard Generic Access Profile (GAP) APIs. It also provides a series of sibles BLE services to help users easily develop GATT services, clients, and GAP. Additionally, the Bluetooth LE service provides multiple GATT-based services. The BLE protocol stack runs on the Bluetooth stack core (LCPU), and HCPU can communicate with the BLE service through inter-core communication mechanisms such as hardware mailbox.

BLE Service Configuration

Users can enable the Bluetooth LE service using the menuconfig tool. Configuration is typically saved in C header files. By default, the configuration is saved as rtconfig.h.

The following example shows flags defined in a project header file:

#define BSP_BLE_SIBLES

After configuration is complete, users need to include the header file in all source code that requires access to data services. Users can also use menuconfig to enable BLE services.
