What do you think?

https://github.com/kotobuki/http-server-block-for-uiflow

I have the exact problem: Chrome 107.0.5304.110 on Fedora 35. All buttons in the UI (label, button, line, etc) are nonfunctional as well as the "load", "save" etc buttons. UIFlow is completely unusable with Chrome. I can reproduce this in Konqueror also.

The buttons seem to work in Firefox though.

Hello @slow-moose

which UIFlow firmware version is running on your M5Core2?

I can use ESPNow blocks from the UIFlow online version 1.10.8 just fine on my M5Core2 running UIFlow firmware 1.10.8.

You can use M5Burner from here to update the UIFlow firmware on your M5Core2.

Thanks
Felix

This looks like a running issues with google chrome as its happening (or not happening as is the case) with other sites that download files.

I have same problem , after some time EspNow recieve callback block returns duplicate message.
Uiflow 1.10.7 , firmware m5 tough 1.10.6

Hello @mchott

in my experience a data SIM (for smartphones, LTE routers, etc.) is not good enough for NB-IoT. You will need a SIM card specifically for NB-IoT plus the NB-IoT service needs to be offered by the provider in your region.

@teastain I try to be helpful!

I managed to solve this issue with this custom block

@isamalatby Do you have a new device or second hand device?

I learned that the browser does connect to the Core2 by WiFi and the IDE connects using USB.
