Close Other Roasting Software

Computer SetupReviewed 2026-10-19

Summary

Many USB, serial, Bluetooth, and device-driver connections can be used by only one app at a time. If another roasting app is already connected, Rostoc may not be able to read the machine. Rostoc then says Port Busy, on Windows and on a Mac. On a Mac, a program that uses the port without locking it can still let it open, and the machine then reads as Device Not Responding: close other roasting software in that case too. For an Aillio Bullet, Rostoc names the app when it can — for example RoastTime Is Open — and waits: it connects by itself once the app is closed.

Steps

  1. Close Artisan, Cropster, vendor software, or any other app connected to the machine.
  2. Unplug and reconnect the USB device or restart the machine connection mode if needed.
  3. Open Rostoc and connect again. For an Aillio Bullet that Rostoc is waiting for, there is nothing to click: it connects by itself once the other app is closed.
  4. If the device still fails, submit a ticket with the machine model and error.
