Error in UART communication between Uno & Nano


#21

no worries about the “delay()” :wink:
I didn’t want to push you, was just curious and can totally understand that you concentrated on 0.24.


#22



xod will try now in new version


#23

receive

Ok, so the first script is for Arduino to send bytes. Not sure what the second script is for?

Now for a simple XOD patch to check if anything is received. Just set the read-bytes patch to poll continuously.

You should be seeing 4Ch and 48h alternately in the watcher. You will also need to modify the soft-uart patch and swap the tx and rx arguments passed to _serial. I mentioned that in a previous post.
