The is a specialized communication channel. It leverages the USB "Bulk Transfer" mode. In USB terminology, bulk transfers are designed for transferring large amounts of data where data integrity is critical, but exact timing is less so (compared to Isochronous transfers).

Most users connect their phone to the remote controller via USB. By default, this connection uses standard Android debugging bridges or networking protocols. These protocols are "conversational"—they require a lot of back-and-forth handshaking. While great for general internet browsing or file transfers, they are inefficient for streaming high-bandwidth video and telemetry data simultaneously.

For developers looking to squeeze every ounce of performance out of the DJI Mobile SDK (MSDK) or Payload SDK (PSDK), understanding the Bulk Interface is not just optional; it is essential.
This is where the comes into play.
If you are building a mission-critical application, don't settle for standard network connections. Dive into the DJI SDK documentation, implement the Bulk Interface handling, and give your users the high-performance experience they expect. Are you developing a custom integration with DJI hardware? Let us know in the comments what challenges you are facing with the SDK!
