Hello, we've set up our Bittle, upgraded to OpenCat 2.0 and calibrated it. Everything works great with 'Petoi Desktop App' also. For a next step, we were thinking of using Tinkergen Codecraft-PC2.0 but I have a few questions about that: 1) Do we have to downgrade to OpenCat 1.0 to use Tinkergen Codecraft w/ Bittle ? 2) When programs are Uploaded to Bittle from Codecraft, how can they be executed? For example, can they be added to "Newbility" and later be callable through serial commands? Thank you, --Mike
