GRToolbox is a mobile APP that can scan Bluetooth LE devices, demonstrate standard profile applications, and jointly debug Profile/Service functions related to Goodix Bluetooth LE platforms, to help users quickly get started with secondary development and debug applications based on Goodix Bluetooth LE SoCs.

GRToolbox supports the following general Bluetooth LE functions:
• Scanning devices (with filter and can list devices with signal strength from the highest to the lowest)
• Showing advertising data
• Connecting to a device, setting connection parameters and MTUs, creating/removing a bond
• Discovering services, reading/writing characteristic values, and enabling/disabling notifications and indications
• Parsing Profile/Service data

GRToolbox provides a rich set of application demonstrations on Profile:
• BPM (Blood Pressure Monitor)
• CSC (Cycling Speed and Cadence)
• HRS (Heart Rate Service)
• HTM (Health Thermometer Monitor)
• RSC (Running Speed and Cadence)

GRToolbox enables users to jointly debug functions related to the following Bluetooth LE Profile/Service on a Goodix Bluetooth LE platform:
• DFU (Device Firmware Update)
• PCS (Power Consumption Profile)
• PPK (Power Profile Kit)
• RELAY (Heart Rate Sensor & Running Speed and Cadence Sensor Relay)
• THS (Throughput Service)
• UART (Universal Asynchronous Receiver/Transmitter)
