Goodix presents GR5526 software development kit (SDK) to help GR5526 series users boost their efficiency in project evaluation and development. GR5526 SDK supports full functionality of Bluetooth Low Energy (Bluetooth LE) Protocol Stack (Bluetooth 5.3), and provides a complete set of peripheral drivers, as well as various library files. It includes a rich set of reference files and examples on Bluetooth LE device roles, GATT profiles/services, peripheral APP drivers, libraries, OTA, DTM, power consumption, FreeRTOS, and LVGL.
GR5526 SDK supports automatic power consumption management and provides multiple low power modes, so that the GR5526 SoCs can run with ultra low power consumption. The SDK also ensures firmware security, by providing firmware encryption and download.
GR5526 SDK facilitates fast project evaluation and development, supporting popular IDEs: Keil, IAR and GCC. It includes essential tools, such as GProgrammer for PC-based download and programming, GRUart and GRDirect Test Mode Tool for PC-based serial port debugging, and GRToolbox for mobile debugging.
To evaluate a development project, users can work with GR5526 Starter Kit. GR5526 SDK provides examples that can run on GR5526 Starter Kit for various scenarios.

GR5526 Starter Kit
GR5526 Starter Kit (GR5526 SK) is a Goodix proprietary platform that helps users quickly get started with project evaluation, development, debugging, and performance verification when GR5526 series SoCs are used.
Read MoreBluetooth: Fixed the disconnection issues in Bluetooth LE multi-connection scenarios in sleep status; resolved memory exceptions in advertising scenarios; optimized the MAC address de-duplication algorithm.
Peripheral: Optimized driver defects of modules including I2C, ADC, QSPI, and RTC.
System: Optimized ultra deep sleep mode, improved the slow clock calibration strategy, and resolved firmware upgrade failures during encryption and signature verification.
IDE: Upgraded the version of IAR (> 9.40.1+), and resolved exceptions in Keil caused by .sct files in encrypted scenarios.
Added display examples for LVGL V8.31, and fixed bugs related to LVGL display rendering.
Removed the tools folder (containing GRToolbox, GRUart, GProgrammer, and GRDirect Test Mode Tool) in SDK. Users can download the tools from Goodix official website "Software Resources".
