For application developers on the application processor. The Qualcomm® sensing hub (QSH) client APIs provide a C++ interface that enables Linux applications to access sensor data from the QSH framework running on the low-power processor. Before writing code, see Data Model to understand the request and event message format.

QSH client API workflow

The session lifecycle for client applications: getSession(), open(), close(), setCallback(), and sendRequest(). Start here before building any sensor application.

Develop applications using the QSH client APIs

Walk through the SessionClient sample application. Covers SUID query, attribute query, and streaming call flow with annotated architecture diagrams.

Configure sensors

Configure sensors using registry files and calibration procedures for the QCS6490 platform.
