I'm thinking to buy M5Stack LTE Module (M8321), but could not find how to use it...

Does anyone has sample code for Arduino / UIflow?

@heybin It works now!! Thank you so much

Hi, I'm using M5FIRE with UIflow.
What I'm doing is sending ENV. sensor data to server.

The code I wrote works when I just run the code from RUN button on UI flow web, but does not work when I download the code on M5FIRE from download button.
Is there any possible issue and solution?
