@daltonb This is very strange! I will connect you with someone who is using Arduino on Catalina on our support team to help you out. You will be receiving an email shortly with a link to set up a call. Thank you for your patience.

@daltonb Can you update Catalina to the latest release? 10.15.3? I think the previous update had an issue where you had to manually enable a lot of things and it might be blocking Arduino in the background. Hopefully this works!

@daltonb Is this an issue uploading or just compiling?
Try with a basic code such as this:

#include <CoDrone.h>
void setup() {
  // put your setup code here, to run once:
  CoDrone.begin(115200);
  CoDrone.pair(Nearest);
}

void loop() {
  // put your main code here, to run repeatedly:

}

I'm wondering if there's a mistake in the default code. Also, are you sure you are using a SmartInventor V2? There should a green sticker on your board if it is. If not, try uploading by selecting the V1 board. I know that Arduino works with Catalina so these are the last few things I would try.

@tserluca Please check your email and be ready with your computer with a microphone. Thanks!

@daltonb Hm..I'm not on Catalina but I did some research and I think I found a build that might work for you. ️ http://downloads.arduino.cc/javaide/pull_requests/arduino-PR-8976-BUILD-869-macosx.zip
Could you try this one and then let me know?

@tserluca Unfortunately, you cannot program RokitSmart with a Chromebook. You need to download the Arduino software. If you have another device, you can follow the instructions here.

@tserluca You can put another board with a third motor to control independently if you have one! As for the error, I haven't seen that error before. I compiled your code on my end and everything compiled correctly. Could you upload another code that has worked before and provide me with the OS and version that you are using?

@tserluca Sorry this got lost! This is actually a RokitSmart question Motor 1 and Motor 3 are paired so they cannot be coded independently. A screenshot of the error would be really helpful

@dmars2001 I sent some information to you. Thank you for your patience.

@nohzen Not all IR sensors will be exactly the same so that behavior is very normal. Just set different thresholds for each IR sensor for detecting objects
