@jsellers Awesome! Let us know if you have any other questions!

@kat,
One more thing I would try is double checking the battery is fully charged and that your propellers are free of any hair or obstructions. If you have crashed the drone many times before sometimes the motor connections weaken. You can set up a time here and we can come up with a solution!

@jsellers ,
Hm..Snap! should have prompted you to install a driver. Did you complete step 2 of this lesson? Without installing the driver you will not be able to connect to your CoDrone via USB. If you have already done so let me know so I can set up a call for further support

@MLC1 ,
Do you mind replying with a more detailed description of your issue? Any videos or screenshots can help us diagnose the problem and resolve it

Hi @kat,
Are you flying in a dark room or over a surface that is very reflective? Your CoDrone will drift and have trouble taking off because the optical flow sensors on the bottom will not work well. Another quick fix I would try is switching two motors on opposite sides in the direction where the CoDrone is drifting. For example, if the CoDrone is drifting to the right, swap out a motor on the left with one on the right. Make sure you double check propeller orientation as well! If you continue to experience problems let me know and we can set up a call

@rcase35 It may the case that you need to continue to connect to that port if you are on a desktop computer. Keep me updated!

Hi @rcase35 ,
Since you are using Windows there is a way to check which COM port the device is connected to. Navigate to your Control Panel >Devices and Printers> Device Manager. From the menu, select the "Ports" drop-down menu and look for the correct port. It will never be on COM1 so it should the other available port. Once you have this information you can open the port manually in the code. For example, if your BLE board shows up on COM3:

drone.pair(drone.Nearest, 'COM3')

It seems like your connection worked before. Did you ever change the USB cable or try plugging it in a different USB port?

Hi @mntrunner ,
Could you attach a screenshot or a video of the issue?
In the meantime, you can try the following:

• Install the Chrome app instead of the native app
• If you are on Mac, you may need to install the Legacy version of the driver twice.
• Double check that the BLE light is flashing red and your CoDrone back light is flashing green before you attempt to pair

Let me know if any of these solve the issue.

@Shawnpike25 ,
The app is Petrone and you can find it on PlayStore and App Store!

@athang ,
It looks like your SmartInventor board is having a problem and you will need to send it back for a repair. I will have someone email you so that it can be arranged
When you get your new board, make sure you also update your CoDrone library. It seems like you have an old version. In Arduino, go to Sketch>Include Library>Manage Libraries...

Search for CoDrone and make sure to click "Update" to the most recent version.
