Thanks!

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

Hello @arkieguy

if you use an M5Stack 5 / 13 should work.

However if you use an M5Core2 you'll need to change the DIP switches in the COM.GPS to 16 / 17. The reason for that is that the Arduino code for M5Core2 uses GPIO 13 / 14 which translate to 16 / 17 in the module.

from Arduino example for M5Stack:

Serial2.begin(9600, SERIAL_8N1, 5, 13);

from Arduino example for M5Core2:

Serial2.begin(9600, SERIAL_8N1, 13, 14);

Please also check this GPIO comparison sheet I've put together a while ago.

Thanks
Felix
