| Use Case | Why the Driver is Required | |----------|----------------------------| | | DJI Assistant 2 sends large firmware binaries to the drone via bulk transfer. | | Onboard SDK development | Direct sending of control commands (velocity, attitude, gimbal angles) from a PC to the flight controller. | | Real-time log streaming | Dumping internal flight logs, sensor data, or debug information at high speed. | | Simulation/HIL | Hardware-in-the-loop (HIL) simulation where the PC acts as a ground station. | | Payload integration | Configuring or controlling third-party RTK modules, sprayers, or industrial sensors. |
In USB architecture, "bulk transfer" is a data transmission mode used for large amounts of data that must be accurate, but are not time-critical. Unlike "isochronous transfers" used for real-time audio or video streaming, bulk transfers prioritize data integrity. This makes it perfect for: The "Bulk" interface refers to a specific type
: This is the primary package for Windows users to ensure all DJI USB interfaces are recognized. You can find it on the DJI Download Center under the "Other" or "Software" category.
Connect directly to a USB 3.0 port on the motherboard (rear USB ports on desktops), not a USB hub.
