Using Preloaded Code

On first boot, Bittle will be running simple pre-loaded code that lets you test the functions with the supplied remote control. After you use Codecraft or other programs to upload your own code, the pre-loaded code will be overwritten, however if you need to use pre-loaded code again, you flash it again, by using Calibrate Servos extension in Codecraft.
In order to re-flash pre-loaded code to BIttle after it was overwritten by user code, open Codecraft.
Then choose Bittle as device, click on Add Extension and choose Calibrate Servos extension. Place the setup-loop and Flash factory code blocks in the Script area and click on Upload.
