There are 2 signs that you’re in upload mode:
- The single blinking blue LED on the Smart Inventor Board
- A flashing red or pulsing yellow LED on the Bluetooth board (both actually work!).
If the LED on the Bluetooth board isn’t pulsing yellow or flashing red, press the tiny black button next to the light to see if you can cycle it into either the pulsing yellow or flashing red.
Are the LEDs on the Smart Inventor board pulsing towards the middle instead of a single one blinking? Sometimes hitting the taller circular black reset button right next to the DIP switch will kick it into upload mode. Or, you can disconnect all power from the board, disconnect the CoDrone battery, plug everything back in, and then try again.
Make sure to check the video to see exactly what upload mode looks like!
You’re in upload mode now! You’ll get to know this mode really well, since you need to use it any time you want to upload a program to your remote.
