@verdicchio Hi there,
I answered on the other thread about why you cannot pair. I also wanted to clear up that there are two Blockly coding platforms, one for CoDrone Lite/Pro and one for CoDrone Mini. Make sure you select the right one that matches with your product.

@verdicchio If you have tried to pair to CoDrone using Blockly without any device connected then it is likely that your device is not enabled with BLE (Bluetooth Low Energy). Since we have phased out Snap! and we are solely using our web-based coding software, you will need to have a BLE enabled device. Most recent laptops and Chromebooks will not be an issue but desktop computers and older laptops will not work.

Another update here! Snap! has been phased out so you will find our Block coding on Blockly, a web-based coding platform. If you want to see our lessons for all of the languages, check out our Basecamp website.

Hi, everyone!
I just wanted to update everyone on the new way to program CoDrone with Chromebooks. At the moment, Blockly programming with a Chromebook. Snap! has been phased out and we only use our web platform that runs on Chrome. Codebender is working on adding our board to their Arduino web editor, but in the meantime, there will be no text-based coding available on Chromebooks.

@sbrels4d CoDrone relies on the optical flow sensor and height sensors for its position. If you have some highly reflective floors or are flying in a dark room, it might be difficult for the drone to stabilize. If you have labeled the bottom of the drones, make sure nothing is obstructing the opening where the sensors are. Let us know if you have any questions! Feel free to attach pictures of the bottom of your drones and the classroom.

@aada2019 The input will correspond to how much battery power is provided to the motors. We do not have information on the exact voltage or rpm.

Hi @aada2019 ,
There is no way to individually control motor speeds aside from the functions on our documentation page. The speeds will vary as it is affected by any disturbances in order to maintain its direction.

@jacksonpope2 I am not sure what you are referring to. The Rokit and CoDrone board are the same but the libraries are different. You can definitely program the board with both libraries but the Rokit library will not be able to program the drone.

@jacksonpope2 To use CoDrone Lite, you will need to program it with either Blockly or Python. You are probably seeing that error because it's not receiving any commands so it disconnects automatically. Check out our coding lessons to get started with CoDrone!

@lexbot2-0 We will be emailing you to send out a replacement board. Thank you for your patience!

@jacksonpope2 If you are trying to program in Blockly, you do not need to connect the Bluetooth board to the computer. Doing so will cause the pairing to fail. If you are trying to pair with Python, try installing the driver found in this lesson. Hope this helps!

@sbrels4d CoDrone Lite is not able to do flips, but CoDrone Mini can do flips with Blockly and Python. The "Master" tab should have been removed. Thank you for pointing that out!

@efraim-fleisher We will email you about getting you a replacement. Thank you for letting us know!

@hmeenen For Blockly programming with CoDrone Pro/Lite, you do not need the Bluetooth board to be connected to the device. Make sure the Bluetooth board is off and disconnected so the drone does not pair to it. Try pairing again on Blockly with the battery in the CoDrone only. Hope this helps!

@digdeeper
Thanks for letting us know! We will look into it as soon as possible.

@vangj We have not tested any other battery with CoDrone Mini so we can't recommend anything other than the CoDrone Mini battery. Some things to be aware of if you choose to try another battery with a higher discharge rate (35C vs 30C):

• The center of mass may be affected which will affect the flight and stability of the drone
• Battery polarities vary and it may not match the polarity of the drone battery

@timmytomate
Some things to note about the camera:

1. Using the camera draws a significant amount of power, almost the same amount as using the motors.
2. Importing the camera takes a long time so I would try to run that only once at the top of the notebook in its own cell.
3. You can use a smaller resolution frame to speed up detection time. Here are some examples of changing the resolution from our docs page.
4. Overall, the main disadvantage is that the camera drains battery really fast and uses a lot of ram/memory on the Pi Zero. Turning it off whenever possible by calling camera.close() will help save battery.

@vangj For now, please include set_trim() in every program to make sure the trim values are set. Have you tried larger values yet? Every now and then we encounter a drone that needs pretty high trim values (above 50). If more than one drone is experiencing these problems, let us know so we can schedule a call with you.

Hello @haziq ,

I responded here as well but we do not support RokitBrick with Zumi. In the other thread, I posted instructions for using block coding with Zumi. Lessons will be coming soon this month!
