Introduction
The Heart Rate Sensor & Running Speed and Cadence Sensor Relay (HRS RSCS Relay) example demonstrates how to apply GR55xx 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 LE debugging App for GR55xx SoCs).
This document introduces how to use and verify an HRS RSCS Relay example in the GR55xx SDK.
