CSR BlueSuite is a Windows-based collection of service and engineering tools for CSR (now Qualcomm) Bluetooth chipsets. It includes utilities such as PSTool (for reading and editing PSKeys), BlueFlash (firmware flashing), DFUWizard (device firmware updates), and BlueTest (RF testing and calibration). The suite enables tasks like changing a device’s Bluetooth address (BD_ADDR), adjusting radio and audio parameters, updating firmware, gathering diagnostics, and recovering unresponsive devices via USB-SPI or UART connections.
Designed for OEMs, repair technicians, and advanced hobbyists working on CSR-based headsets, speakers, and USB dongles, BlueSuite typically requires a compatible USB-SPI interface and corresponding drivers. Because it operates at a low level, incorrect changes can render a device inoperable, so it should be used with care.
