Hi,
I got an M5Fire and a QR-Code Scanner with the Atom Lite. I want to send the results of the QR scanner to the M5Fire via UART, and I connect them with a Grove cable via Port C on the M5Fire (which I bought last week).

I can make it work, BUT

1. it only works when I download it via UIFLOW, I can not test it live from UIFlow, because then it runs into an error
2. The setup to make it work is different from what I would expect (Tx and Rx have to be switched).

You can see the screenshot attached, which makes it work:

If I run it "live", I get the following error though:
Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.

Which I saw being attributed to the pins being used otherwise.

Can anyone help me shed some light on that?

Thank you so much

I had the same problem, it seems like on S3, the libraries are not extended that far. I was struggling though with the touch count. When I touch the screen, it increases to 1, and even after a 10sec sleep, and a "touch update", it still shows 1 for another two iterations, until it goes back to 0.

With this, it's kind of not usable for me unfortunately. I will have to wait for the next proper version I assume?

I am struggling slightly with using the NeoHex with my CoreS3 in UIFlow 2.0. I can get it to work with the normal RGB unit, as apparently no RGB LED units are available.

However, I can not adjust brightness and it's awfully bright

Hmm, so that means I can not use any of Grove connectors for this? I tried with the other hint provided about alternatives, but don't get it to work... Sounds like I need to sent back the Fire and get another M5Stack Core version?
