Establishing Connection with Central Device
The Bluetooth Low Energy connectivity is added to the application that is used to connect with the
Bluetooth Low Energy central. The first step is about the management of Bluetooth connection with a
central device. When using ATBTLC1000 device, this process is managed by dedicated API function calls
associated with ATBTLC1000 events handling.
The interaction between Host MCU, ATBTLC1000 and Bluetooth Low Energy central during connection
establishment is as follows:
Figure 3-1. Establishing Connection with Central Device
On host MCU side, the management of the Bluetooth connection is performed through three main steps.
1.
GAP callback registration
2.
Advertisement configuration
3.
ATBTLC1000 event handling
In the existing project main routine, the integration of these steps are highlighted in red in the following
flowchart.
