Goodix presents GR533x software development kit (SDK) to help GR533x series users boost their efficiency in project evaluation and development. GR533x SDK supports full functionality of 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 Mesh.
GR533x SDK supports automatic power consumption management and provides multiple low power modes, so that the GR533x SoCs can run with ultra-low power consumption.
GR533x SDK streamlines 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 GR5331 Starter Kit. GR533x SDK provides relevant examples that can be directly run on the GR5331 Starter Kit Board.

GR5331 Starter Kit
GR5331 Starter Kit (GR5331 SK) is a Goodix proprietary platform that helps users quickly get started with project evaluation, development, debugging, and performance verification for GR533x series SoCs.
Read MoreBluetooth: Supported LCP 1 kHz, optimized the approaches for handling abnormal data packets, fixed the disconnection issue caused by parameter update at Bluetooth LE 2M PHY, resolved memory exceptions in advertising scenarios, optimized the MAC address de-duplication algorithm, and improved multi-connection stability.
Peripheral: Modified driver defects of the UART and I2C modules, and improved the ADC calibration strategy.
System: Resolved wakeup exceptions in ultra deep sleep mode, improved XO stability during chip boot, resolved SRAM data retention exceptions in low temperature conditions, optimized ESD performance, and improved the slow clock calibration strategy.
IDE: Upgraded IAR IDE (V9.40.1 and later versions required).
