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!
Hi @mz !
If you are using Blockly to program CoDrone, you don't need the remote at all! You can go ahead and turn off the remote to make sure it isn't pairing to your drone first and preventing your computer from finding it. If your Macbook still can't find your CoDrone, please do the following steps and let me know what version Bluetooth you have.
Thank you!
@brennsteph You can build any track you would like and use basic driving commands found here to navigate! To learn how to use IR sensors and camera to make decisions while driving, you can follow our tutorials on Workbench. If you don't want to make your own field, you can purchase one here from us. If you are still having doubts or technical issues, use this link to set up a time and I would happy to speak with you. I hope this helps!
Hi @drone123 ,
You are correct that the sensors we have onboard for distance measuring are facing the ground. There are IR sensors in the front but they are for transmitting and receiving messages for drone "battles" and not for distance, unfortunately. You could try using the FPV camera for detecting obstacles. It is a separate module that we are no longer selling but if you could somehow get your hands on one that would be my suggestion! Although we don't offer support or tutorials, there are a few projects that I have seen on the forum that use it. Hope this helps!
@alpha You don't need to run all three functions 
You can stick with the last one only. The middle one is if you know your drone's four-digit ID. The example given uses '1234' but you can find out your drone ID by looking at the output once your drone pairs. Let me know if you have any more questions!
@alpha Try the following steps if you are having difficulty pairing:
drone.pair(port_name = 'COM3')
drone.pair('1234', 'COM3')
drone.pair(drone.Nearest, 'COM3')
Let me know if this works for you!
@mrschunsclass There was a mistake in the labeling of the battery. Sorry about that! Flip the battery in such a way so that the wire is pointing toward the back. If it's a tight fit, you can remove the dual-lock velcro and try orienting the battery vertically instead. As long as the connector reaches and nothing is puncturing the battery it will be fine. Thanks for the question!
@bmartin_ascte Hi, thanks for the great question! You can pair to any drone in the room as long as you find it's 4 digit ID, so you could design an activity or mockup scenario where you write code and send it to another drone to "hack" it. Some other activities include a drone mission where the pilots fly it to a given location and send morse code signals by programming the LEDs. There are no security settings necessarily but you can design a curriculum around this theme!
@greenestarr45 Unfortunately, we are no longer carrying those. Thank you for your inquiry.
@jy2010 Sure! Send your video to leila@robolink.com and I can take a look at it for you.
