Firmware or RoasTime driver issues - READ THIS

Please note that you can only use one version of the Roastime software at any given time. If you choose to switch from the current version to the legacy version, or vice versa, you will have to uninstall and reinstall the drivers.
Unfortunately we cannot make this any easier at this moment. We do however encourage users to stick with the most current version, as there are new releases every week. For any special feature requests, we would love to hear them.

Please start by updating to firmware version 448

Problem: After updating the firmware, the Bullet is no longer starts up:
Why is this happening: Something went wrong during the update process. We are investigating why this is happening to some users.
Solution: Please use this guide on how to solve this problem.

Problem: After updating to V448 I cannot connect to the legacy RoasTime ( anymore
Why is this happening: Aillio now have our own USB international ID which only we can use. This new ID is implemented in the new firmware, thus needing a driver update.
Solution: Re-install the USB drivers. Go here to download the USB drivers again. Look on page 31 of the manual on how to re-install the drivers.

Problem: After using the new RoasTime 2.0.X I cannot connect to the legacy RoasTime ( anymore.
Why is this happening: When you install RoasTime 2.0.X, new windows drivers are automatically installed for you and these override the old drivers.
Solution: Uninstall the new drivers and windows should roll back to the old ones by opening device manager then selecting Universal Serial Bus devices. Right click the Aillio LTD-Bullet and choose “Uninstall device”

Then tick off “Delete the driver software for this device”, then click “Uninstall”

Now, unplug the bullet, plug it back in look in the device manage again. If the Aillio LTD still shows up under the “Universal Serial Bus devices” then repeat the above two steps once more.
Finally the Aillio should be found under the libUSB-win32 devices as shown below:

Problem: I imported my json files from the legacy RoasTime to the new RoasTime 2.0.X but not all profiles are shown correctly or some temperatures are not correct
Why is this happening: You may have incorrectly imported the json files found in the Aillio folder. Please export the roast profiles first, then import the folder containing the exported profiles.
Solution: Open the legacy RoasTime. Right click on the list of profiles and select “Export all profiles”. A new folder is created named Exported and these files should be dragged into the new RoasTime.

Problem: I imported my json files from the correct Exported folder but my data is incorrect
Why is this happening: Bugs and unforseen weird old profiles may not import correctly.
Solution: Try importing the json files again using RoasTime 2.0.6 This newest version should improve the importing part.
