M5Core2 no MQTT on download

simmoe

This has been published before, but it is really both obvious and a major bug. Simple to describe: MQTT never connects or works after you burned your software to the M5Core2

Hello @simmoe

not sure why you are writing that. Anyways, if your UIFlow code requires a WiFi connection and you want it to work after burning/downloading the UIFlow code, you'll need to make sure WiFi gets connected first. Try to add something like the first two statements I described in this post.

Thanks

Not sure what you are trying to say.
I have literally wrote a book on the subject and MQTT works fine.
We need more information on your issue.

You're right. Tnx. But why does my other products work WITHOUT the wifi-connection block? Have burned a variety of M5sticks/Atoms without having to use the block. If it's mandatory, why not use it in the UIFLOW examples?

Hello @simmoe

I don't know why it does work with your other products, sorry. I think the UiFlow examples are made for quick testing functionality, e.g. via using Run option, which uses the already existing WiFi connection. But yes, I agree, it probably would make sense to include them in the examples.

Thanks
