Hi,

I tried uploading code to the CoDrone Pro remote, and I receive an error message with feedback that says "the selected serial port does not exist or your board is not connected".

I checked the following items with a few run-through to make sure that the steps of connection are correct and I was not missing anything.

• Switch 1 is Up, Switch 2 & 3 are Down
• Pressed the "Reset" button under the switches and bluetooth button before upload. I see solid red light under Power, blinking blue light on Led 18, and blinking yellow light above Bluetooth button (sometimes can be blinking red).
• Selected the correct board (Rokit-SmartInventor-mega32_v2) and the port
• Used different USB ports and computer systems (Windows & Mac)

I still run into the same issue. I have copied the detailed error message. Sorry about the long post.

Arduino: 1.8.5 (Windows 10), Board: "Rokit-SmartInventor-mega32_v2"

avrdude done.  Thank you.

the selected serial port 
 does not exist or your board is not connected

Please let me know if there a fix for this. Thank you!
