Trouble with sending serial data from Arduino to Max

Henry Mills's icon

I'm trying to get Max to read serial data that's being sent from an Adafruit Circuit Playground Bluefruit(connected via USB), but Max doesn't seem to be reading anything. I've attached a picture of the patch I'm using. It's borrowed from somewhere else on the internet, but I'm not seeing any posts about this issue past 2016, so I was hoping someone would be able to offer some help or just tell me if this even works anymore.

Here's the arduino code and serial output as well:

I'm having the same issue and haven't found much help on the topic. Using the suggestion above to enable dtr didn't change anything for me. Do you happen to be using a Mac running Ventura? For me that is where I've had issues reading serial data from arduinos into Max. But with macOS 11.3 it works fine.

@ MJ
if you looked at the screnshot, it would have told you that this is windows machine ....
nothing to do with Mac - arduino problms.
That boards use nRF52840 chip which works over serial port
only if on enables DTR.

Hi, I tried enabling DTR and it works now. Thanks!
