What is this?
DJ 4G Hub is a local-first macOS console app for controlling compatible first-generation DJI 4G modules over USB. It lets you check device status, send/receive SMS, manage eSIM profiles, monitor network traffic, and run AT debugging commands, without modifying the module's firmware.

The release bundle already ships libusb, so no Go, Node.js, or Homebrew install is required.

Current releases only target Apple Silicon; an Intel Mac build is still unverified, and iPhone/iPad support is just a planned roadmap item. The extra USB modes (usbnet=2/3) are also still experimental.

It's a one-click tool that only activates the module's USB network-card mode, without needing the full DJ 4G Hub console.
