I also tried changing the following settings:

frame_buffer_count: 2 frame_buffer_location: dram

and

priority: 1000

lowered resolution to 320X240.
and

External_Clock frequency: 8MHz

All without success.

Hello @mb

M5Atom Matrix has a dedicated USB-Serial chip which is not affected by the ESP32 reset and thus is keeping the serial connection alive.

In contrast the ESP32S3 inside M5AtomS3 Lite has USB built-in (and doesn't need a dedicated USB-Serial chip). The 'downside' being what you observe - resetting ESP32S3 also resets the USB connection.

Thanks
Felix

The r-relay-unit looks promising. But how do I get power to the controller (M5 Atom, etc)?

thanks,

@kkkkkk Maybe, you can try M5stickC-plus

Hi, you can click the link to know more about it

Then probably the fact that Atom S3 currently supports only tiny subset of UIFlow features should be made clearer in the product description. I bought an Atom Matrix for a DIY watering project, was fairly impressed with the device (and the whole M5Stack concept) and decided that small local display for current humidity etc would be even better. So I bought the new AtomS3 (described as supporting UIFlow development platform) and currently can't connect it neither to my Watering sensors nor the MQTT data collection server. I will switch my development back to the Matrix and will be looking forward to switch it again when the features I need will be supported in UIFlow 2
