Hi @ronbolts ,
It sounds like your CoDrone is running low on battery, but just to be sure can you attach a screenshot of your code? If you are experiencing skipping commands, try including a wait block for half a second to a second between your move commands. Let me know if this still does not resolve the issue!

@ksmith20 Make sure you always take out the battery after each attempt and plug it back in. It takes practice to get it right! Sometimes if you place CoDrone on the ground a little too early it may not work. While CoDrone is upside down, try waiting for the white flashing sequence to finish before placing CoDrone back on the floor.

@dragongod,
Please run !pip3 install matplotlib as well and it should solve your issue! We will make sure to add that to the lessons.

@armando9000 We apologize for the trouble but I am glad you could get it fixed!

@thang123 Sorry to hear that! Our team would like to schedule a call with you to see the cause of the issue and try and resolve it. You will be receiving an email shortly to the email associated with your forum account. Thank you for your patience.

Hi @armando9000 ,
The black 4-pin connector is supposed to be crossed in that way. I understand it can look misleading!
For your 3-pin colored connector, that is definitely incorrect and it may damage your board if you power it on. Thank you for bringing this to our attention! I will contact you shortly to your email associated with your forum account so that we may get a replacement out to you.

Hi @PimV ,
I can clear that up for you! I have found the best way is to press and hold the button while holding it right-side-up, waiting for the eyes to turn blue, then turning it upside down. Once you see the flashing white pattern in the video, you can place it right-side-up on the floor where it will take off. If it doesn't take off, keep trying to calibrate! It takes a bit of practice to get the timing right.

@adl_2020 I will contact you about getting you a new one. Please check your email associated with this forum account and you will hear from me shortly!

@adl_2020 Sorry to hear that! Can you try and power your BLE board on its own with the USB cable in our kit? If you see anything other than a red blinking LED then you may have a damaged BLE board. Could you also send a picture of your setup and BLE board? I just want to visually check for any damaged components. Thank you!

@patrick-huber Unfortunately, the latest release of Catalina is no longer compatible with our board We are currently working on updating our firmware so that it is compatible, and we will let you know once we have an update! In the meantime, you would need to downgrade Catalina to 10.14 or use a Windows machine to program the SmartInventor board with Arduino. You can also avoid using the SmartInventor board by following our tutorials for programming with Python. We apologize for the inconvenience but we are addressing the issue. Thank you!
