Uploading Programs to the Remote

Connect your Bluetooth board to your Smart Inventor Board with the 4 pin connector. Next, connect your Bluetooth board to your computer with the micro USB cable.

Get your Smart Inventor Board in upload mode by flipping DIP switch 1 on. DIP switches 2 and 3 should still be off. Next, hit the reset button (below the DIP switches). After a few seconds, a single blue LED should start blinking.

There are 2 signs that you’re in upload mode:

1. The single blinking blue LED on the Smart Inventor Board
2. 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.

YES! You can upload code now! Open up Arduino and go to Tools > Board to select your board. It should match the version that’s on the front of your Smart Inventor Board. For example, if you have Smart Inventor Board V2, your board should be Rokit-Smartinventor-mega32_v2.

Note: If you have a newer version of Arduino, the board may install inside of Tools > Board > Arduino AVR Boards.

The COM port is related to which USB slot on your computer the controller is connected to, and how many USB devices have been plugged into the machine prior. Each new device is assigned a new COM port number. To check which port you’re connected to, go to Tools > Port. For most users, your COM port may be the only one that shows up, or you’ll see a COM1 and another COM port number! If you’re on a Mac, your port will most likely be SLAB_USBtoUART. Just as a warning: COM1 is never the correct port.

Can’t remember which board or port you’re on? Check the bottom lefthand corner of Arduino, and it will have your board and port in order! For example, if you have Smart Inventor Board V2 and you’re on COM 4, you’ll see something like Rokit SmartInventor-mega32_v2 on COM 4.

Ready to upload a code? In Arduino, go to File > Examples > CoDrone > Control > FlightController to upload the default flight controller program. Click the upload button (arrow pointing right) to start the upload. If everything goes well, the bottom console should say “Done uploading.”

After you’re finished, don’t forget to exit upload mode by flipping DIP switch 1 back to the off position.

Good luck and happy coding!
