Hello, I am trying to set up communication from Bela to an Arduino Uno for an instrument project using the Tx/Rx pins P9_11 and P9_13. However, when I run the example Pure Data serial communication example from the dev branch, I get this error:

I've tried hooking the Tx pin up to an oscilloscope too and just get a flat 3.3V, no data. Do you have any idea what could be the issue? For reference, here is the Bela version I am running, and here is the pure data example code (I've also tried running just the transmit or receive individually and still get nothing).


Thanks in advance for any advice you may have!

No I had not. I just tried that and it seems to be working now, thanks!
