Introduction
The Heart Rate Sensor & Running Speed and Cadence Sensor Relay (HRS RSCS Relay) example demonstrates how to apply GR5xx System-on-Chips (SoCs) in scenarios with multi-roles (Peripheral and Central) and multi-connections, to enable functions of an HRS RSCS Relay device. The HRS RSCS Relay device can serve as both a collector and a sensor.
- Collector
As a GATT Client, the HRS RSCS Relay device receives measurement data from heart rate sensor as well as running speed and cadence sensor.
- Sensor
As a GATT Server, the HRS RSCS Relay device sends the received data to other collectors, such as GRToolbox, a Bluetooth Low Energy (Bluetooth LE) debugging App for GR5xx SoCs.
This document introduces how to use and verify an HRS RSCS Relay example in the GR5xx Software Development Kit (SDK).
