GRCalibration is a Goodix proprietary Bluetooth calibration tool to calibrate the crystal frequency offset for GR551x/GR5405 SoCs and PLT. By controlling the clock signal of the target device, it enables the target device to generate single carrier signals that can be analyzed with a spectrum analyzer to observe frequency offset. This capability allows precise adjustment of the XO-Offset, ensuring accurate calibration to meet specified Bluetooth frequency requirements.
Supports connection via UART.
Supports crystal calibration for PLT and GR551x/GR5405 SoCs.
Enables single carrier signals on the target device for calibration.
Persists calibration values into NVDS, eFuse, or OTP.
Automatically records the date for persisting calibration values into NVDS.
