Hello @ajb2k3

I took a look on your UIFlow handbook for some examples on serial communication.

I found this:
0_1680074762436_101c0ef1-393b-4e13-9081-d0d4be3f153c-image.png

It seems the code is almost the same than the one generated for me by UIFlow.

The imported libraries are the same than the ones I have in my code:
from m5stack import
from m5ui import
from uiflow import

On the example provided by my reader's provider; they import this library: " #include <SoftwareSerial.h>"

https://wiki.seeedstudio.com/Grove-125KHz_RFID_Reader/#play-with-arduino

But I think this is the implémentation for Arduino and I guess the equivalent UIFlow libraries are loaded through this:
from m5stack import
from m5ui import
from uiflow import

Do I miss something ?

On my side I think the reader works because when I bring a RFID tag close to it; the status led of the reader lights up.
But I still receive nothing on the M5 core RX PIN

Thank you for your help
Best regards
